hi Hans

nice sternbergia.I flowered candida for the first time last year,I bought it from Christian about 10 years ago.It was a complete dissapointment,one I think better seen in the wild which I have not done,I am always too late.

Hi Hans,
so beautiful plant and so early ! Mine will not flower that year, too little bulb. Last year my candida made seed pod and my cat cutted it with his teeth before maturity !!! I was sad and desappointed !!! Perhaps it will flower again in 2008 with more chance.

Hans, this is an interesting Sternbergia, but about S. candida: this flowered with a friend here in
Holland already in December. He told me this was because of the very warm weather in April last year.
I'll have a look in Gartenflora.

Here is Sternbergia sicula, in flower now. This form is derived from a collection made by Dr John Marr near Dodona (JRM 3186). Coming from the northern part of the species’ range it does not require a hot,  dry bake to make it flower (though it will tolerate such treatment).

Whether I cosset or neglect it, this Sternbergia always flowers for me.  Not sure why yours does not flower, nor what I can suggest to improve your chances.

Remind me next year and I will send you a couple.

Post by: Gerry Webster on September 02, 2008, 08:18:29 AM
Arthur - many thanks for the offer. Looking at your pics again I'm not sure that this is the plant that Alan gave me. Yours looks as though it might be S. greuteriana,  just coming into flower with me.

Gerry you are not alone we grow two types of Sternbergia foliage, sicula and lutea.  Mind you ours have never seen the sun since early May this year, it's now official August in this area saw  60% lesssun this year.  To think I wasted my money on sun block, we are all looking (apologies to all Scots here for spelling mistakes) peelie wallie (which I think equates to pale and interesting).

Since  is you, Shelagh, I will allow the translation of peelie wallie as : pale and interesting, though it is perhaps better as:  pale and sickly!! :P :-[

I am glad you merged the two threads, as I had missed the earlier one - altho' it did puzzle me until I got to your post.

Has Ian had a chance to look at my post.  Gerry thinks that my Sternbergia might be greuteriana, but they are not like the one in Ian's bulb log, nor like photos on Google.  Would appreciate his thoughts.

I'll draw this to Ian's attention, Art, though since we are working off a laptop at the minute, the quality of the pictures we are seeing is not up to much, so ID may be difficult!
Title: Re: Sternbergia 2008
Post by: Gerry Webster on September 02, 2008, 12:47:51 PM
Art - I wouldn't go to the stake over this identification. My S. greuteriana has quite small flowers & my guess about your plant was based on the size of the flowers in relation to the size of the pot (of course it might be a very big pot!)

Maggi - my apologies, I hadn't noticed the previous posts on Sternbergia

"What size are the flowers on Alan's plant?"

Gerry

From soil to top of flower 8.0 cms   Flower is approx 3.5 cms from the bottom of the ovary to the top of the flower.   Flower width of course varies with the amount of opening, but is generally not more than 3.0cms.

You may be right about this form of S. sicula Anthony, but I find it matters with a Cretan form of  S. lutea I grow. This needs a roasting to flower & will not perform outside in a raised S-facing bed even in my hot garden.

I thought it was only found on Crete but according to RBG Kew & Paul Christian it is also found on Karpathos. The Karpathos form  is described as having obtuse petals & being stoloniferous. My - rather miserable - form of  S. greuteriana, if it is that plant, has pointed petals  & is not stoloniferous.

Art - Yes, my plants of S. greuteriana also emerge with the leaves & on a slant. I suspect this may be the Cretan form.  I'm wondering whether yours is the Karpathos form which seems to be  both less common & superior. The key feature seems to be the presence of stolons. If your plant is not S. greuteriana it's difficult to know what it could be given the size.

I am now able to post pictures of my greuteriana, together with sicula.  Not the best photos I have ever taken, but the weather today has been atrocious and it was dificult to get flowers to open.

I am repeating my much admired sternbergia, and I think it is now obvious that it is not greuteriana - the flower is at least twice the size of greuteriana.  The flower is also about 60% the size of my sicula.

Middle two pictures are greutriana, and the last one is sicula
Title: Re: Sternbergia 2008
Post by: Gerry Webster on September 06, 2008, 10:33:10 PM
Art - I agree that your  'mystery' Sternbergia looks different to both your greuteriana & to mine. And my greuteriana looks different to yours! I'll try to post a picture when I have more flowers & less rain - in these conditions photography is virtually impossible. It would be really useful to know where Alan collected the plant & what he thinks regarding its identity.

Arthur, I am taking a break form trying to sort out our on going PC problems to catch up on the recent forum postings.
Your pot of Sternbergia sicula is beautiful whether it is true sicula I am not clear.
What I am convinced of is that most of what I have grown as sicula is at best a hybrid between sicula and lutea if not just a small narrow leaved variation of lutea.
I suspect S. sicula is like the one you show but as the best paper on Sternbergia is in German I am unable to find out the latest opinions.
I do not think that flowering with or without leaves is a reliable diagnostic as it can vary from season to season depending on temperature and moisture levels.
One thing for sure is they are all beautiful and you are lucky to flower them so well.
Hopefully I will be able to show some of mine flowering soon.

Sternbergia  greuteriana.
This was given to me some years ago by Erna & Ronald Frank. I don’t know  its origin. S. greuteriana is recorded from Crete & the Karpathos group of islands. Collected forms from Karpathos are reported to be stoloniferous & to resemble miniature forms of S. lutea. This plant is not stoloniferous &, insofar as it resembles anything, it is some forms of S. sicula. My guess, therefore, is that it may be Cretan in origin. I find it  not very free flowering &  suspect that it needs more of a summer bake than it currently receives
Title: Re: Sternbergia 2008

Title: Re: Sternbergia 2008
Post by: Gerry Webster on September 15, 2008, 02:17:06 PM
Sternbergia sicula cv. ‘Arcadian Sun’.
This form derives from a collection (C529) made by Herbert & Molly Crook in 1966 in the Peloponnese. It differs from the John Marr, Dodona  form  - posted on 1st Sept. -  in several respects; most significantly, as can be seen in this photo, it usually has two flowers on each scape rather than one

Title: Re: Sternbergia 2008
Post by: Gerry Webster on September 15, 2008, 06:00:15 PM
‘Sternbergia lutea angustifolia’ (not a currently accepted name). From a collection (MS 753) made in Crete by Mike Salmon. Plants distributed under this name are thought to be natural hybrids between S. lutea & S. sicula.
Title: Re: Sternbergia 2008
Post by: ashley on September 15, 2008, 06:38:35 PM

Title: Re: Sternbergia 2008
Post by: Gerry Webster on September 15, 2008, 09:36:01 PM
Ashley - I don't really know but I doubt it. I have the impression that these hybrid forms are quite common in the wild.  Yes, it is a nice plant & my photo doesn't do it justice (as a rank amateur I find Sternbergias difficult to photograph)  but, unfortunately, it is virused, so its future is in doubt.
Title: Re: Sternbergia 2008
Post by: Maggi Young on September 15, 2008, 10:02:14 PM
Gerry, the plant looks pretty good in the photo... is that the virused one?
You know, I am always keen to get rid of virused plants but I've been thinking about the fact that some plants seem to carry the virus without too much effect being seen to their health..... what about making a fine mexh cover for pots with "suspect" plants... very fine metal mesh, too small for aphids to pass through, fitted over pots to quarantine contents... one could still enjoy plant......anyone think this is a good idea?   Not sure if I'll run this past Ian any time soon......he gets anxious about such things :-X
Title: Re: Sternbergia 2008
Post by: Gerry Webster on September 16, 2008, 12:12:30 AM
Maggi - yes the photo is of the virused plant. Ironically, this is its best ever year as regards flowering - the flowers are a good 5cm in diameter. In earlier years the viral symptoms only showed in the leaves but this year they are  apparent in the flowers too. I'm very fond of this plant -  it is so vigorous & so attractive that my inclination is to keep it,  segregated in a different part of the garden perhaps. Maybe this is foolish? I would imagine that any mesh small enough to exclude aphids would also exclude light. Regular insecticide sprays perhaps?

Ashley - I don't really know but I doubt it. I have the impression that these hybrid forms are quite common in the wild. 

Is this not because they are just natural variations of one species, which they were considered to be for many years before a 'splitter'got hold of them
Title: Re: Sternbergia 2008
Post by: Gerry Webster on September 16, 2008, 09:20:57 AM
Tony - You may well be right, but on the basis of my, admittedly very limited, experience I incline to the view of the 'splitters'. From a horticultural point of view the plants I grow as S. sicula  are quite distinct from those I grow as S. lutea. However, I've just recalled the situation with Bulbocodiums,  so perhaps, botanically, I should join the 'lumpers'? Incidentally, the RBG Kew  checklist regards 'sicula' as a subspecies of S. lutea.
Title: Re: Sternbergia 2008
Post by: Tony Willis on September 16, 2008, 10:09:38 AM
I think the problem with plants in cultivation is that people tend to dig up the better looking ones or ones with obvious differences to the norm.I cynically do not believe that wonderful plants in cultivation miraculously appear spontaneously from a random pinch of seed from the wild. This was always still on a special form of the plant from the previous year having survived the ravages of winter.

There is a huge clump of sternbergia growing in the dirt outside the cemetery gates in Milas, Turkey.I am going in four weeks  and if in flower will take some pictures and make some very amateur observations.
Title: Re: Sternbergia 2008
Post by: Gerry Webster on September 16, 2008, 01:01:47 PM
Tony - I think you are probably correct. However,  I think it's useful (if nothing else) to make distinctions for horticultural purposes even where  there are no distinctions of botanical/taxonomic significance.
I look forward to seeing your pics from Milas - let's hope they are in flower.

Hi,

Just now I write on this post, because I would like to see my  plants to bloom, to can show them here.
I like very much these plants, but have no experience with them. All I know is from the bulbs I have, they start grow the leaves in autumn, but from to year to now, no signs of flowers. Sometimes I wonder if they are realy Sternbergia or another plant ::) The leaves are just like the S. lutea, but don's know more.
By now it should already be the time to flower here, wright? :'(

Cris & David - Sternbergias need to be well-fed & to be kept hot & dry during the summer in order to flower well - probably hotter & drier than you think is good for them. In my garden S. lutea is later than other species.

David - During the Summer I keep potted Sternbergias  in full sun, plunged in sand  in a S. facing lean-to frame. No water at all. When I first tried this (in despair) I thought it would be certain death but they love it & flower like mad.
Title: Re: Sternbergia 2008

I agree with Gerry when he says that Sternbergia require hot dry conditions in the summer - and yes, hotter than you might think sensible.  Unlike Cyclamen graecum, where we were told to bake them to get good flowering - only to find they do need damp at the roots that should continue to grow - Sternbergias can be baked as the roots do not continue to grow.

Every one of my pots has flowered.   :)

Not sure what happened here - possibly I bought some bulbs at a plant sale that were incorrectly labelled.

Certainly not Sternbergia, and it will be interesting to see if they are peshmenii or reginae-olgae.  I think it was a bargain even though not what I thought I had bought.   :) ;) :)

Well Art, at least you got something  worth having. A few weeks ago I bought a packet of  Sternbergia lutea in a garden centre with the intention of trying them in the open garden. The leaves have just emerged & they are obviously & thoroughly virused. Beware garden centre Sternbergias!

Thanks Gerry and Luc,

I started last year to replace my old loamy soil with a sand/compost mix.

When I lifted some weeks ago some of the bulb baskets in order to label them I recognized a much better growths rate compared to previous loamy situation. It seems the efforts paying off!

Gerry,

A lot of treatments while dormant can create symptoms the first year that look like virus, but I don't know whether this is the case with Sternbergia.  I know that heat treatment of daffodil bulbs often gives distorted growth the first year, which is fine the following year once the plant has settled.  Given that you plants are so obviously ill, I'm wondering whether their treatment by the bulb companies may be the reason, rather than virus?  The first season is always a difficult one to be sure IS virus.  I am very aware of virus, and have destroyed plants where the symptoms have persisted, but sometimes the anomolies of the first year are never repeated.

Sternbergia identity -

I recently posted (Sept 14th, post no 34) a pic of a plant, given to me by the late Erna & Ronald Frank, which I identified as S. greuteriana. I now think this plant is more likely to be the much rarer S. pulchella from Syria. Those interested might care to look at an account by Erna  of a trip to Syria  with Manfred Koenen  in which they found S. pulchella (in AGS  Bulletin  vol 64 no 4, Dec 1996). Brian Mathew provides an  account of S. pulchella in 'The Garden' vol 118, pt 1 (Jan 1993) & my plant corresponds closely, though not exactly, to his description.

Pasche and Kerndorf stated in ' Die Gattung Sternbergia ' (2002) for Sternbergia pulchella - Flower stalk during flowering invisible, when in fruit prolonging to 1,5 -2 cm

Your plant has a distinct flower stalk which does not exist neither in a photo shown in the account mentioned above nor in the pic of the AGS article. So maybe your plant is something different than S. pulchella.
Sternbergia is a very tricky genus. There are a lot of hybrids between Sternbergia lutea, sicula and greuteriana and a correct determination at least for the smaller forms of these, is very very difficult.

Title: Re: Sternbergia 2008
Post by: Gerry Webster on September 28, 2008, 01:00:38 PM
Gerd - thanks for your note. I agree  that the identification of Sternbergias is a problem & I am by no means certain that  my plant is S. pulchella; you may be right, it could be a hybrid. In most respects it conforms to Brian Mathew's description though the  length of stem in my plant does concern me as does the relative length of the style. To my eyes the plant in Erna Frank's  photo appears to have a short stem though it is  difficult to determine from the angle of  the  photo how long it is. The photograph in 'The Garden' (by Brian Mathew) of a plant growing at Kew shows a definite stem, admittedly not as long as on my plants but my plants are growing in rather poor light. Another reason for thinking it might be S. pulchella is that it came from Erna Frank. Unfortunately I lost my original note of its identity(I was obsessed with  frits at the time to the exclusion of everything else) but most of the more unusual Mediterranean plants  grown by the Franks were from their own collections.  It would certainly be very valuable to have an English translation of the Sternbergia text you mention
Title: Re: Sternbergia 2008
Post by: Gerdk on September 28, 2008, 05:44:15 PM
Gerry,
After I posted my remarks concerning the stem I had the feeling that I was a little bit overhasty. If you have a look at some other species of Sternbergia the length could be a variable feature - why not with pulchella? A botanical diagnosis isn't always correct - especially when it was based on a single or few plants (or from 1882 in this case).

Here is an attempt of a translation of the Pasche & Kerndorf article (without personal liability) ;)

Description: Bulb 1-1.5 cm in diameter. Leaves 3-4(6), narrow linear, appearing with the flowers, canaliculate (channelled), keeled, arched downwards, bright green, , with narrow light central stripe, obtuse or slightly pointed, 7-11(15) cm long, 0,5-0,7 cm wide. Margins rough (scabrid?).
Flower stalk during flowering invisible, when in fruit prolonging to 1,5-2 cm. Flowers sessile, yellow; segments narrow linear, circa 1,5 cm long, about as long as the tube (POST 1896).
Filaments of different length. Spathe circa 0,5 cm, silvery with green margin, bifid at the apex. Fruit circa 1,5 cm long, circa 0,5 cm wide, pointed (pointy?). Seeds with elaiosom.

I hope so too Gerd! It's what I hoped after translating the Latin description of crocus. Anyhow many thanks.This description is very similar to that published by Brian Mathew & based on living material.

Post by: pehe on September 29, 2008, 12:01:00 PM
Franz, I am green of envy. Your Sternbergia meadow are outstanding!

Here in Denmark, Sternbergia needs a warm place near a wall to flower well in the open garden.
This year my Sternbergia flower very early (1-2 month earlier than normal), and surprisingly the ones in the open garden about 3 weeks before the ones under glass.
I think that is because we had a long hot and dry May followed by a rainy Juli. The bulbs must have thought that July was September.
I have seen the same effect on my Colchicum montana, Col. agrippum, Acis autumnalis, Galanthus rgo and Schizostylis coccenea but not on crocus. They flower at normal time.

1. St. sicula Dodona Gold
2. St. greuteriana
3. St. lutea
4. St. sicula graeca
5. Sternbergia wall
6. St. lutea virus?
7. St. lutea virus?
I think the last 2 has virus, but I am not sure. 5 years ago I had a large clump of lutea, which showed signs of virus (stripes on the leaves), but they performed very well with lots of flowers and increasing fast. As they performed so good, I moved them to other places in the garden(!!!), to observe them further. Now they still look healthy and flowers well, and the stripes has disappeared on some of them. So is it virus? Or is the stripes symptom of some lack of minerals?
Fortunately, all my other Sternbergia have no stripes.

Post by: Gerry Webster on September 29, 2008, 01:54:00 PM
Poul - Very nice Sternbergias. I was interested in your experience of possibly virused plants. This year I obtained some new plants of S. lutea & when the leaves emerged about 2 weeks ago they looked quite obviously virused. Now they look a nice dark green & very healthy with no virus-like markings at all. Very odd.

Title: Re: Sternbergia 2008

Cris & David - Sternbergias need to be well-fed & to be kept hot & dry during the summer in order to flower well - probably hotter & drier than you think is good for them. In my garden S. lutea is later than other species. 

Gerry, thanks, I'll follow your tips.  I'll not forget "probably hotter & drier than you think is good for them"  ;)

One question: how hard is cultivate this plant from seed? Sorry for my question of a starter, but I've never tried to sow these plants ::)

Hello from Linz, Austria!

Here are some Sternbergias from my collection. They all grow near a south facing wall and get all the heat our summer throws on them. I feed them regularly and heavily, no additional watering. I think, it is difficult to feed Sternbergias enough in pots to grow them to their full potential here.

Sternbergia lutea from Garden Centres
Sternbergia sicula from Corfu (my best collection, although I have no plants of Dodonea Gold or Arcadian Sun)
Sternbergia from Crete (I am not very sure about this, I think too big flowers for greuteriana; Sternbergias from Crete are very confusing)
Sternbergia clusiana from Turkey

Gerry, I think there could be two explanations:
1. The plants are virused, but the visibility of the virus markings change accordingly to how well the plants are feed. (Or to the age of the leaves.)
2. The plants are not virused, but due to bad weather conditions or some misfeeding (maybe lack of lime) the leaves show virus like markings. Has anyone seen that?  Or what is the sign of misfeeding on Sternbergias?

As I mentioned I have planted the suspicious Sterbergia on different locations far away from my healthy ones (even some at my summer residence), to find out if they really were virus infected or if the markings was related to the soil. Now I have looked close at them all, and I must admit that all of them still have virus markings to various degrees. Where the soil is rich in lime, the markings are almost invisible (the last two pictures in my previous post). In some years the markings are more pronounced than in other years.
My conclusion is that they have virus and that I have to discard all the suspicious ones. :(
By the way does anyone know if virus distribute via the soil or is it only from aphids?

Title: Re: Sternbergia 2008
Post by: tonyg on October 01, 2008, 08:35:30 AM
I agree with your observations about virus symtoms being 'masked' by good growing conditions.  I have observed the same in my bulb collection. 
I have not heard that virus can be transmitted through the soil (BAD news if it can) but of course we can pass it through handling infected bulbs and there has been discussion on the forum about transfer by pollinators.

Poul - I think you may be right regarding the age of the leaves. I just found a piece on the internet which states that this can be the case with bulbous irises. I'm not sure about lime - all my Sternbergias are grown in a compost which contains 40% limestone chips. They are regularly fed with a high potash fertiser.
I have one Sternbergia which is certainly virused - both the leaves &, to some extent, the flowers are marked. Nevertheless it remains very vigorous & free flowering.

I have not heard that virus can be transmitted through the soil (BAD news if it can)
Tony - I am not an expert in this field, but my understanding, in relation to snowdrop viruses, is that they can be spread in basically 3 ways viz

- through handling infected bulbs
- transmission by aphids
- transmission by nematodes in the soil

If this is the case for snowdrop (see section on Viral Disease in the 'Snowdrops' book by Bishop et al) then I would have thought there was every likelihood that it would apply equally to other plants & this seems to be borne out in the AGS publication 'Pests and Diseases of Alpine Plants' by Ellis, Entwistle & Walkey (see section on Viral Diseases - Transmission by Eelworms (Nematodes)).

For snowdrops affected by virus, which are planted in the garden, the advice is to remove the plant (avoiding hand contact by placing a plastic bag, or similar, over the plant), remove the immediately surrounding soil & safely dispose of both - timing is key here & if at all possible this should be done before the soil starts to warm up, because this is when the nematodes become active. Oh, and don't forget to wash hands & clean the garden tools afterwards!

Sorry to harp on about snowdrops, in the Sternbergia thread ::)

The third picture shows a small S. lutea, perhaps with some influence of S. greuteriana or vice-versa.
All pics from today in Erich Pasche's greenhouse.

Thanks for the pics  Gerd. I now think that my plant, initially identified as  S. greuteriana, but, for a time, thought to be S. pulchella, is, after all, S. greuteriana. These small Sternbergias (& maybe the big ones too)  were put on earth to torment us.

Gerd,
many thanks for showing us pictures of Sternbergia greuteriana of the collection of Mr. Pasche, one of the Gurus of the genus.
I grow two collections of greuterianas, but after seeing these pictures I am no longer sure about their correct identification.
The first is from Janis Ruksans without any data on their origin, the second is from Karpatos.

In his Monograph of the genus from 2002 , Pasche used the length of the filaments for distinguishing between sicula and greuteriana: 10 - 17 mm for sicula and 15-32 mm for greuteriana.
I am also not sure, if this key is right when using it on the big flowered siculas from north-west Greece; but on the other hand, these are easy to identify.

All the best from Linz

Herbert,
There are a lot of plants from Crete or the adjacent islands to the east which are
in between greuteriana and sicula/lutea. So you can have all transitions between them.
According Erich Pasche a typical greuteriana has small and narrow perianth segments with a rounded tip and long filaments.

I was questioned at the SRGC Weekend about Sternbergia identification: I could only say that most were yellow, some were large and some were small, flowering with, or without leaves, which may, or may not, have a white central stripe..... :-[..... my questioner was less than happy with my answer, but it was the best I could do!  :P :-X :-\ :'(

Sternbegia clusiana is in flower now in many localities across Israel,
usually on dry Eastern facing slops.
I took a picture this week of this particularly nice plant; big Tulip sized flower with green tips.

I grow mainly S. clusiana leaves, they are really 'spoilt' and generally just refuse to flower in any size pot.

It is easy to notice the nectar glands at the inner tip of the petals, ants are really attracted by it to than slip inside the flower and climb the anthers...very clever technique.

Post by: Gerry Webster on October 18, 2008, 10:55:31 AM
Oron - that S.clusiana is very handsome. Thanks for showing it. I've had a bulb for 10 years & never seen a flower even though it is planted out under cover. Last year there were not even leaves though the bulb is still alive. It's interesting that, even in Israel, it can be difficult to flower.

Post by: Oron Peri on October 19, 2008, 10:48:43 AM
Thanks Gerry and Dominique.

Dominique, clusiana germinate easily and grow relatively fast, in my experience it is better to plant it out in the garden in its 3ed season, in the hottest spot. they are quite hardy, some colonies get snow here.
They flower really nice if they are undisturbed in the garden.

Hans, It is from Paul Christian. He claims it is from Karpathos acquired from Bonn Botanical Garden.
I admit it looks like a sicula, but it makes offsets on stolons so I am pretty sure that it is greuteriana. I have not heard of any sicula doing that.
The width of the leaves is about 4 mm.

Mark,
You are right, I put some stones behind the Sternbergia to get a warmer micro climate.
I do not serious mean to grow Sternbergia in my kitchen garden, but these had increased very well in my rock garden (in fact too much, as my rock garden is pretty small). I therefore put them temporary on a free space in the kitchen garden until I found a better place. But time flies and now they have been there for 3 years and they are doing quite well.

Gerry,

The flowers are quite small. Here is a size rank of flowers in my garden (decreasing size):
1. S. sicula Dodona Gold
2. S. lutea
2. S. sicula graeca
4. S. greuteriana

On the first picture you see closest to the camera sicula Dodona Gold, greuteriana(the same plant as above, but a month earlier) and lutea.
It is not easy too compare sizes, but the flowers of greuteriana are clearly smaller than lutea flowers.

The other photos are the same greuteriana at different times

Poul,
This seems to be a never ending discussion. I am far from beeing an expert, especially concerning this tricky genus but it seems there is no Sternbergia lutea and also no S. greuteriana.
According the key from Kamari & Artelari S. lutea has bright glossy green leaves without a central stripe. Furthermore lutea and greuteriana both have perianth segments which are rounded at the tip while sicula has acute ones.
In my opinion the best way to identify a greuteriana is to measure the perianth segments which are (1.2)1.5 - 3 cm long and 0.2 - 0.8 cm wide.
Nevertheless I admit freely that I am growing a Sternbergia lutea for more than 10 years which is in fact sicula (never took a closer look until recently). Also I got a greuteriana whose perianth segments are only  2 mm too wide for matching the description. All species mentioned above are able to produce hybrids which eachother.

Hi Poul at all ,

Thank you for your informations to your plant .

I have supposed that your plants comes from P.Christian - I think this is one of the often commercial sources for this plants .
A bit strange for me is the number ( MK 0187 ) - as reference from B.G. Bonn is given : Koenen 21823
The plants of the firstdescription ( Kamari ) comes not from Karpathos - they are collect from eatern part of Crete .

I have never seen a stoloniferus Sternbergia -so maybe you can send us a pic of this plants if you ever repot / replant .

It is not a must that St. greuteriana is stoloniferus - it is only written :
" bulbs up tp 2,5 cm in diameter ,sometimes with stolones or bulbils ......"
on the pic of herbarmaterial is shown a normal bulb !

To plantmaterial from Karpathos :
My idea was earlier too that all material of Sternbergia what came from Karpathos must be St. greuteriana - this is definitiv wrong !
I have visit Karpathos in fall ( last year ) and I found two mountains with Sternbergia ( please look for my report ) - this plants are St. lutea or hybrids with between St. lutea and St. greuteriana or St. sicula.

I agree with Gerd that St. greuteriana must have rounded at the tips of perianths - your plant shows acute tips like St. sicula .

Before some weeks has a friend from this forum shown also a St .geuteriana ex PC and some doubts rise up in me .....

I suppose the other ( for me true ) forms of St. greuteriana comes from Crete and they are distributet more seldom so that we have now this confusing situation.

This is my private opinion after all facts which I know - a finaly judgement which plant is what is only possibly with research of the DNA .

Anyway : thats all really interesting and nice plants

This plant is stoloniferus, but unfortunately I can't show it to you.
The bulb was planted in sept. 2003. Soon after a nice roset of leaves appeared, but no flowers. In November some new Small leaves appeared about 6 cm from the original plant. That was the first sign of the stoloniferus nature. I was excited as I have never seen such a behavior before. In 2004, I moved the plant to the present place at the wall, and then I saw two small bulbs on stolons. Unfortunately I didn't take any pictures. As it is planted directly in the soil, and it performs so well with lots of flowers, I will not replant it in the near future. But when I do, I take some pictures, I promice.

What I really like by Sternbergia is their ability to withstand bad weather.
The last two weeks have been very windy with lots of rain and even some freezing nights. But the Sternbergia flowers are very rugged and they still  look great.
These lutea have just started flowering. They are offsets planted 2 years ago and grows 1 m from the wall where the motherplant have been flowering for two months! (second picture) That shows the benefit of a warm wall when growing Sternbergia in cold areas.

Most of my Sternbergias have flowered early and many flowers have been pollinated.
Even in the garden many Sternbergia set seeds.
Two years ago I got seeds from lutea, greuteriana and sicula Dodona Gold too, with the result that I now have seedlings of them all.

I was using Collins Mediterranean flowers as my field guide.  There were only two possibilities listed - lutea and sicula.  These plants were strong and not delicate, which made me think they were lutea.  However, I had never seen a Sternbergia before so I could be wrong.  The stripe you see may be light reflections on the leaves.

Hello Tom ,

thank you for your answer .

I'm far away to say for shure this is sicula or lutea or a hybrid ....Sternbergia are so confusing .

In the Sternbergia 2008 topic are pics from Arthur ( page 3 ) ....they looks for me similar to your plant .

It is really interesting that such plants grows also on Lesbos ....and not only one Crete !

Not only the stripe ( maybe a reflection ) is it why I have doubt - it is also the form of the leaves ....

Hans - I too think I can see a stripe on one leaf.  I also  agree that  these plants look rather like those posted by Arthur. However, doesn't the most recent publication argue (convincingly)  that sicula, lutea & greuteriana  are all lutea?

For what it is worth, we found Sternbergia in two locations.  Near Agiassos next to a small chapel and many clumps on the road between  Akrotiri Agios Fokas to Polichnitos.  I have to correct the date, it was 12 October 1996.

Sternbergia colchiciflora is in flower now in many parts of north Israel.
Some photos taken last week.

I have been growing this species for the last 7 years, they flower beautifully every year.....under the surface level!!!  >:( and so i get only seedpods regularly but can never enjoy visible flowers.

Oron, interesting variation with this species.
What's the difference concerning the growing conditions between your cultivated
plants and those which occure in the wild? Do you have a guess for the lack of
visible flowers with your plants?

Gerd
Title: Re: Sternbergia 2008
Post by: Oron Peri on December 05, 2008, 12:20:29 PM

Gerd,

Probably the lack of optimal conditions is the cause for this phenomenon.
in the first years I taught i missed the flowers while i was away but than i read somewhere about it...

This phenomenon occurs also in the wild, and was described allready in the 1930's by a Russian botanist.

I find some of the sternbergias to be really spoilt ans some species just refuse to set flowers if they grow in a pot.

Title: Re: Sternbergia 2008
Post by: Anthony Darby on December 05, 2008, 12:47:22 PM
For several years I have had Sternbergia colchiciflora in the alpine house in a pot. It produces seeds with no visible flowers every year. Last year I put one plant outside in a trough and it flowered. This summer the bulb must have rotted due to the damp. :'(

Thank you, Oron.
The same ugly behaviour as a lot of violets have, they build seed without
an open flower. Not bad for the plant, only for us.
Is Sternbergia pulchella occuring in Israel? It is recorded from Lebanon
and Syria.

Gerd,

S. pulchella does not grow in Israel.

From the short descriptions available [never saw a photo of it] I suspect it to be a form of S. colchiciflora.

Unfortunately the only way for me to check plants in Syria and Lebanon at the moment, would be from the bottom side of the bulbs...[if you know what i mean...]
My dream is to get there one day and find out all the plants we assume to grow there and for sure there are many surprises to be still discover.
Hopfully soon....

Oron - there is an article by Brian Mathew (with photo) on S. pulchella in 'The Garden' (Jan 1993). Brian claims that it is related to S. colchiciflora  but differs in having well-developed leaves at flowering time. He  claims that there are also small morphological differences but the chromosome number is the same - 2n = 20. He proposes retaining it as a distinct species. Given the history of Sternbergia taxonomy, it seems to me an open question whether this distinction  will survive further investigation.

Post by: Oron Peri on December 05, 2008, 03:54:05 PM
Thanks Gerry,
I will try to get a copy of the journal  you have just mentioned.

 As I said it sounded to me like a form of colchiciflora, leaves hysteranthous or synanthous in some other species gave the plant a Varietal status, I'm afraid there is too little information still  on S. pulchella.

Thanks to this marvelous forum I allready have a copy of the two articles,

The structure of the leaves is very different from those of S. colchiciflora.

Oron,
Isn't it sad that plantmaniacs cannot receive a special status? Why can't we go to all places we want to visit in search of those plants we are keen on?
I also would like to go to the Lebanon - especially for Viola libanotica - as well as Irak and Syria must be most interesting concerning  violets.
We need a special status which indicates: This is a person which is totally harmless, not interested in borders, military areas or defence works.
But I guess this will remain a dream. Nevertheless let's have a dream.

We have two species: S. colchiciflora and S. clusiana.
In the area of Jerusalem there are a few colonies of S. lutea but these where probably introduced in the past by Greek monks.

Oron,
 the latest and definate {at the moment] work on the Sternbergia is :
 Die Gattung Sternbergia WALDST.&KIT. , by Pasche E. &H. Kerndorf [2002]
 with detailed descriptions and cultural notes , as well as coloured photos of all known species , including S. schubertii , a species described in 1840 , and lost , and rediscovered in 1998 in Antalya Prov. , Turkey.
 According to this work S. pulchella is not a form of S . colchiciflora , but is nearer to S,schubertii , but larger flowered and more handsome.
 In my eyes S. clusiana is the most beautyful species ,which only flowers here after a hot and dry summer.

    Gerd ,  I too dream about visiting countries like Lebanon , Syria , Israel ,
 Turkey , Iran , etc. to see all my beloved bulbous plants in their native habitats , but as I am getting a bit long in the tooth , it will remain a dream!

This is very interesting,
Never heard about the rediscover of S. schubertii, maybe this is the 'missing link' to understand S. pulchella...

From Paul Christian's (Rare Plants) website on S. fischeriana: "Most of the stock in cultivation stems from introductions made from Kashmir where it is planted in cemeteries. It is probably not wild there, but is planted in Moslem cemeteries and is also an escape from these. The wild range is said to run from Turkey to China but makes no allowances for this".

Shure I know also this informations with Sternbergias in Kashmir -why not ?
they grows from Azerbaijan, Iran, maybe Irak ....
In Orient is it usual that this plants ( Sternbergia ) are on cementeries ..., but I have it aso seen in France !

In India ,Thailand and other coutries are often Zephyranthes -look in Ebay and there are a lot of sellers which sells Zephyranthes ( also yellow )

Quote
Referring to a trip to the Crimea:     Excellent surprise was discovering of small population (some 200-300 sq.m.) of Sternbergia colchiciflora.  It is quite rare in Crimea and Dima never before found it. Fortunately it keeps blooms open even in rainy weather. We walked all the day crossing yaila and nowhere found another one spot of it. Crimean population can to bloom underground and you can see plants only in spring when leaves and self-pollinated seedpods come out. I got report from Krasnodar district (Russia) about same. All my previous stocks originate from Turkey and they are “normal” blooming. It will be very interesting to compare those. Sternbergia colchiciflora is the single species successfully growable outside here as leaves are formed in spring only. Sternbergia candida can be grown outside here, too but it is not safe.

An article about Sternbergias forwarded to me by Ian Young was very useful for me.
During visit to Greece I was confused because couldn't identify undoubtedly Sternbergias - one clump seemed to be sicula, another lutea and between them a lot of intermediates. Greuteriana I know only by plants got from other growers and in my collection they looked different from lutea/sicula, only one of last acquisitions got under name sicula I renamed as greuteriana this autumn. But all this "carousel" with stocks as lutea angustifolia etc. now is clarified. So really possibly the best would be to regard them as garden forms of one species. Still not so certain about greuteriana but it is for too little knowledge about its variation range. Extremes of course are very different.
