Hi Hans,
can you tell us how you grow this one? I've only managed to flower it once and I wonder now if it is too hot where it is. Yours look nicely shaded.

Yes - it seems to feel like home here. :D

@ Fermi, this species and also St. fischeriana grow in difference to the other species in the (light) shadow of shrubs or stones in a heavy limesoil in my garden – cannot say if they grow in nature in the same way  as the few pictures of them taken in habitat (for example from Oleg Polunin) normally just show the flowers – but if I remember well in literature it is mentioned to grow together with Cedrus libani.

I grow S. candida, along with other sternbergias, planted out in a S facing, permanently covered bulb frame which is kept completely dry in summer.  Although a few of my plants flower regularly I would not describe them as free-flowering under these conditions & I have wondered whether a cooler situation might be better. The other sternbergias flower freely.

I recently discovered this site -

http://www.cyclamen.org/cse97Tsit.htm

which records Cyclamen Society Expeditions. It gives a clue as to how the sternbergia  grows in nature.

"97/10T

21/04/97 Mugla province. Mendes Dag, near Fethiye. Alt. 1440m. Shade: 100%; Aspect: North; Slope: 10-90°; Soil pH: 8.3; Soil type: Rich red soil over limestone. North facing cliffs and slopes thinly covered by mainly Cedrus libani. Moist soil in crevices, on ledges and under Cedar. Heavy soil, humus rich. A large population.
Cyclamen trochopteranthum growing with: Phlomis fruticosa, Quercus coccifera, Colchicum macrophyllum, Sternbergia candida, Chionodoxa forbesii, Cedrus libani, Juniperus foetidissima, Gagea sp., Corydalis ?wendelboi "

Sternbergia sicula
From a collection  made by John Marr (JRM 3186/75) at Dodona. I find this to be the most reliable form of S. sicula  that I grow.After a very poor summer, other forms from further S in the range of the species show no sign of flowering.
(unfortunately, my camera is not too good with yellow).

Great sicula, Gerry. If all these flowerbuds are formed in a bad summer, there must be a tremendous number after a good summer!

My Sternbergia under glass continue flowering.

1. Part of my bulbframe. The Scillas are shooting leaves, and the Sternbergias have flowers.
2. and 3. St. sicula from Korfu top of Pantokrator
4. and 5. St. greuteriana
6. St. lutea

Outside I have seen the first flowerbuds of sicula Dodona Gold and lutea.

Shelagh and David,

I have success with Sternbergia lutea and sicula in my garden, but they require a warm sunny place and a fertile soil to flower well.
Feeding with bone meal and sulphate of potash give good results.
The photo is from last year. The wall is south facing. Here they performs very well.

I grow them in pots too (under glass). The roots goes deep, so in general I use rather large pots. They like to be crowded, but then heavy feeding is necessary. Sometimes when I only have few bulbs I place them among 'dummy bulbs' of limestone.
Last year I have tried 11 cm pots for sicula, greuteriana and colchiciflora. (The pots you see in post #22) Until now it seems OK.

My Sternbergia under glass continue flowering.

Those are very well grown. Please describe the soil mix you use, preferably in excruciating detail so those of us who live in far away places have some chance of mixing something that works equally well.

I have for long had a nagging idea that the mix I use for pretty much everything just isn't right for Mediterranean bulbs, so I'm especially curious about pH, how gritty the mix is, what kind of grit and soil you use, nutrient levels, any additives.

PS: I am interested to see you using square pots; few gardeners do in these larger sizes. I switched to square "one gallon" pots (really 2.5 liters) roughly 20 years ago, and any round pots that come in with nursery stock are quickly recycled. I managed to get a really good deal on some hundreds of used square pots and guard them very carefully! My coldframes hold each a nice tight array of square pots 6×9, 54 pots per frame.

Friends gave me some bulbs of Sternbergia lutea a few years ago and advised me to plant in the hottest part of my garden.  In full sun they perform well every year and have to be split up every 2 - 3 years.  I give a top dressing of bone meal, if I remember.

Among all of you successful sternbergia growers, I'm curious as to the coldest zone in which the hardiest species is known to survive. 
Herbert, it seems you might have the coldest climate of those who have responded here so far - what zone are you in?

Sternbergia lutea is often offered here in fall at garden centers (but then, so are a few other things that have next to no chance of survival).  I've tried it a few times over the years, but have yet to have one survive, hence my questions.

I use basically the compost Ian Young recommend: 2 part loam, 2 part grit and one part leaf compost. As I live close to the see I have a good free supply of sea grit. It is not sharp, but has some broken shells. Grit size is 2-6 mm. (I test the drainage, and if the water not soaks fast enough I add some more grit.) To this I add some bone meal and for Sternbergia some lime. PH is about 7.5

St. lutea can survive in cold areas. I grow mine in open garden, many of them unprotected. They have survived -22 degrees without snow cover.
But the problem is flowering. If too cold there will only be leaves. To flower well, they require a hot, dry summer bake. Try them at a south facing wall.

Post by: Gerry Webster on September 09, 2009, 12:18:55 AM
I don't think the soil mix is particularly important for Sternbergias - any old bulb mix will do. What is important in my experience is good feeding & very hot conditions during dormancy (& I mean VERY HOT).  Given less than ideal conditions, some forms flower more readily than others. I find the John Marr form of S.sicula, which I pictured, to be pretty reliable & I would imagine 'Dodona Gold' to be similar since it comes from a collection made in the same area. On the other hand, S. sicula 'Arcadian Sun' - from a collection made in the Peloponnese - seems to require more heat than it in got my garden this year despite being planted out under glass in a south-facing site.
Title: Re: Sternbergia 2009
Post by: Pauli on September 09, 2009, 05:38:06 AM
Lori,

I suggest I garden around hardiness zones 5 to 6. But usually we have quite hot summers with many days around 30C - so a good summer baking is no problem for the sternbergias here.
Sicula from Corfu is in full flower, but little else noow; I think they are waiting for more rain!

all the best from Linz

One reason to regret the demise of Woolworths is that they were a good source of bulbs. They were unwittingly selling Cyclamen mirabile ( among other species) as C. hederifolium and packs of Sternbergia which were descibed as 'from Turkey'. I bought some packs of this Sternbergia lutea which have flowered well in the garden ever since.

You have a good memory Melvyn since it is many years since Woolworths were a good source of bulbs.  In my garden all the Galanthus nivalis & various forms of Chionodoxa & Crocus  came from them though I never managed to establish their dried cyclamen. Innocents that we were, it was great fun visiting the stores in Autumn to see what was new - all wild collected I fear.

I bought from Woolworths too for many years and always found their bulbs excellent but you had me rattled about stock from the wild so I looked through my tin of labels and was pleased to see they were from cultivated stock grown in Holland  :)  An enterprising manageress in the UK bought the Woolies she worked in and is adding other stores and employing the original staff - renamed it is a great success - maybe they will reintroduce a bulb section  ::)

I still have one Cyclamen mirabile bought from Woolworths, late 70s or early 80s.  I remember having one or maybe two dozen Cyclamen hederifolium, some with interesting leaves, growing in trays.  I had reasonable success getting them started in the greenhouse.  Unfortunately they all died in a severe cold spell in the winter 1983-84.  I lost most of my Cyclamen then but one of the three mirabile survived and is still lingering on.

What sternbergia is this? The bulb probably came from Avon Bulbs 15-20 years ago, disappeared, but last fall came up and flowered: a total surprise! I divided it last fall after noting that it seemed to have clumped up nicely, and this year have 10 bulbs that are flowering or in bud, and another 8 or so not flowering.

Unfortunately, I have not retained any Avon catalogs nor any record of my purchases from them.

The leaves are narrow and have a pale stripe down the middle reminiscent of Galanthus reginae-olgae.

I appreciate that its difficult to tell the size of the flowers from a photograph so I've just been to measure them. The Sternbergia sicula from Oros Idi has a petal length of 30mm and a width of 8mm whereas the S. grueteriana has a petal length of 25mm but only 4mm wide, the leaves when they emerge are much narrower on the S. grueteriana and it is generally smaller in all its parts.All of the plants photographed were growing under glass although I think they would all grow ok outside here in Surrey.

Gerry, have you tried St. lutea Autumn Gold or St. colchiciflora? They should flower in the open garden in Brighton. I have a form of lutea, which have flowered every year since 1993 in the open garden in Denmark. And I believe that the climate in Brigton is much warmer than in Denmark (climate zone 7).

Poul - I tried to get S. lutea 'Autumn Gold'  from 'Rare Plants' this year but was told that it was not available. Next year maybe. I have tried ordinary 'garden centre' S . lutea which grows but does not flower. I have very heavy clay soil - maybe this is a problem?

Gerry, I have also bought the 'garden form' of lutea and these are not floriferous in Denmark. In average 1 out of 6 bulbs flowers. I have sandy soil in my garden, where I have most of my Sternbergias. I have a summer residence too where I have planted some lutea. There the soil is heavy clay, but they grow well and flower about 2 weeks earlier.

The difference may be nothing more than differing nutrient levels. Sandy soils tend to be lean and impoverished; bulbs which require a lot of nourishment to build themselves up (most do) often do better in a nutrient-retentive clay soil.

Never one to give up easily, let me suggest that it's soil temperature that is important, and with clay soil, it needs to be dry. Damp clay won't warm up as well as dry.

How's that for a save?

The same clone of lutea (what I call 'Villa Carlotta', as I get I from there. It is similar to 'Autumn Gold') flower equal well in sandy or in clay soil. The only difference is flower time. I think that is coursed by small difference in temperature. Here is a list of my lutea from 2008:

Clone                    Soil            Flowering time     Flowers            Plant site
'Villa Carlotta'         bulb mix      26. Aug              Many               Pot in green house
'Villa Carlotta'         clay             2. Sept             Many               10 cm from S-facing wall 100 m from the coast
'Villa Carlotta'         sandy         16. Sept             Many               10 cm from S-facing wall 5 km from the coast
'Villa Carlotta'         sandy           5. Oct              Many               1 m from S-facing wall 5 km from the coast
'Villa Carlotta'         sandy          12. Oct              Many               In my open kitchen garden 5 km from the coast
'Autumn Gold'         sandy          10. Oct              Many               1 m from S-facing wall 5 km from the coast
'garden form'          sandy           1. Nov              Few                 10 cm from S-facing wall 5 km from the coast
'garden form'          sandy           8. Nov              Few                 2 m from S-facing wall 5 km from the coast

All are well feed.

Hi Poul,

They are growing in a thin terra rossa type soil over limestone. May to late August sees little rain and temperatures to 40c.
September will normally see a sharp drop ( 10c ) in average dyatime temps and a week of heavy rain. The weather brightens up again and within a week to two weeks Sternbergia colchiciflora begins to flower. Interestingly the same cues seem to bring Colchicum autumnalis and Spiranthes spiralis into flower depsite their growing in quite different habitats!

Some years ago I also found some nice green Sternbergia luteas on a similar place like that - they looked a bit dry but ok.
The next year the leaves showed virus  - I threw most away but kept some bulbs in a pot for one more year to see how they will look like - the plants flowered normal and the following year the leaves looked healthy and strong and no signs of virus were visible.
It seems good feeded Sternbergia (luteas) do not show virus in opposite to stressed plants (Zhirair mentioned something similar in Crocus).

A few posts back Poul asked for photos of virused Sternbergia. I think this plant is infected. The symptoms are clearest on the leaves but are also visible on the tepals - not as obvious in a photo.
Despite the infection, the plant remains vigorous & floriferous. Unfortunately, it is clonal & self-sterile so there is no possibility of raising virus-free plants.

It seems there are some difficulties to determinate the species mentioned above. The following pics show 3 different Sternbergia specimens, the first two were sold as S. greuteriana, the third one (from Karpathos) is very near to it at least.
The petal width is 5,5 mm (first one), 8,2 mm (second) and between 6 and 11 mm
(last).
For me no. 1 fits the description for greuteriana, but no. 2 and the smallest
in the pot of no. 3 belongs either also to it or they are some intermediates with Sternbergia sicula/lutea.

Gerd
Gerd (& Anthony) - A recent paper [EWAN GAGE & PAUL WILKIN Botanical Journal of the Linnean Society, 2008, 158, 460–469] argues that the botanical distinction between S. lutea, S.sicula, & S. greuteriana cannot be maintained & that they should all be sunk into S. lutea. The  authors suggest that the current species might be retained as horticultural cultivars.

Gerd  

Well, since many gardeners have little interest in botanical distinctions I suppose they can continue using the existing names for the time being &, of course, a number of forms in cultivation already have cultivar names. In the case of those that don't I suppose  one could use something along the lines of: Sternbergia lutea (= "S. greuteriana") or  "Sternbergia greuteriana" (= S. lutea).

Addition - I suppose one could also use geographical origin to distinguish them: 'Corfu Form', 'Cretan Form' & so on.

I have occasionally encountered Sternbergia sicula in Crete and the Peloponnese that have more than the usual number of petals and on one occasion saw a plant in the Peloponnese that was a 'double'. Since I was given this one, which was found in the Kotsifou Gorge many years ago, it has always  produced seven or eight petals.

I hesitate to call all these Sternbergias 'lutea' because they are distinctly different. What names should be used to distinguish them from each other?

If you accept that these "species" are conspecific, Sternbergia greuteriana would become Sternbergia lutea Greuteriana Group, and S. sicula would become S. lutea Sicula Group. This is how Daphne retusa is treated - it's conspecific with Daphne tangutica so technically is called Dephne tangutica Retusa Group.

Just how a group name (a horticultural category, not a botanical one) is published validly, I don't know. Perhaps someone here is sufficiently familiar with the code for horticultural nomenclature to tell us?

Cultivar names are subordinate to Group names, so you might have Sternbergia lutea Sicula Group 'Gerd's Delight'. (Using a possessive form like that may contravene the rules, however.)

Incidentally, if you peer closely at the rules regarding cultivar names, it's clear that they were devised by people speaking languages with a clear distinction between nouns (or substantives) and adjectives. I think it would be amusing to assign cultivar names using languages that take a different cut on things. Some North American Indian languages, for example, have single words where in Indo-European languages you'd have a complete sentence. Thus you could have a cultivar name with the meaning "This flower shines like the sun in the field and amazes the plant collectors." In honor of the recently passed International Pirate Talk Day, hardy-har-har, m'lads!

Gerry, thank you for the photos of virused lutea.
Here are some of mine Sternbergia in flower.

1. St. greuteriana from PC (I refuse to call it LUTEA as it is so different)
2. The same two days earlier
3. St. lutea from Villa Carlotta in Italy
4. St. lutea close up
5. St. sicula 'Dodona Gold'

By the way, my St. clusiana's have been eaten by some Narcissus fly grubs >:(, and I think some of my lutea clumps have been visited by this nasty fly too :'(. Have any of you experience with Narcissus fly and Sternbergia?

Here is one I bought as Sternbergia lutea sicula. It is very different from Ian's #2. Poul, your greuteriana from PC has very pointed tepals. I have only once seen what I would regard as a 'classic' example of greuteriana, and it had tiny flowers with rounded tips to the tepals. I have been searching for this form ever since.

Anthony - I only have one form of S. greuteriana, given to me by the late Erna Frank (probably from a Manfred Koenen collection). The shape  of the tepal tips seems to vary somewhat  on successive flowers from the same bulb - relatively pointed to relatively rounded. I should have some spare bulbs & can send you some next summer if you like.

Some post ago I mentioned that I might have a Narcissus fly attach in my Sternbergia. Unfortunately I was right.

Here is the story:
I was happy some times ago as I saw that almost all plants in a group of Sternbergia sicula 'Dodona Gold' had flower buds. Specially as this group is placed in the open garden and therefore normally not flower so well. But I got a bit worried as one of the flowerbud did not develop as rest of them. And as the leaves started to get yellow I decided the dig it up. And I was right. The bulb was hollowed by a grub. After killing the grub (I admit with pleasure) I cut of the rotten part of the bulb. As the roots looks healthy I will give it a try. I have powdered it with sulphur and replanted it in almost dry compost too see if it can survive.

1. The plant with typical signs of a Narcissus fly attach: Undeveloped flower and yellow tipped leaves.
2. The bulb with the grub visible inside.
3. The nasty little devil!
4. The hollow bulb.

Now I am very worried about my Galanthus Reginae Olgae, as they are the preferred target in my garden.

I wish you have avoided any Narcissus fly attach!

Luc - 'Dodona Gold' is said to grow & flower outside if conditions are favourable (i.e., hot). Based on my own experience with other Sternbergias in a fairly hot garden in Brighton I am a little sceptical & would be inclined to lift them when dormant & store them like tulips.
I don't grow this form but it is obtainable from Paul Christian (Rare Plants) & comes from one of his own own collections (with Antoine Hoog) made in 1987.

Yes they performs good outside, specially if they are placed where they can get lots of sun. Luc, I can send you some bulbs in June/July, when I am replanting. If you can't wait until then, you can still buy them at Paul Christian (rareplants).

They get bone dry in the greenhouse, and as I had a chameleon wandering around inside, I had the door closed this year. The windows are screened and open automatically. In previous years flowers seem to have stayed below ground as I find mature seed pods later on.

Title: Re: Sternbergia 2009
Post by: Rodger Whitlock on October 03, 2009, 04:53:36 PM
. . . flowering below soil is depending the enviromental conditions . . .

There are cold adapted bulbs that, if given insufficient winter chilling, do not elongate their scapes properly. Erythronium grandiflorum is one. I have a few bulbs of this originally collected as seedlings on Mt. Prevost (http://maps.google.com/?ie=UTF8&ll=48.832549,-123.765707&spn=0.012543,0.027552&t=p&z=15) just outside Duncan, BC, where it grows on cold north-facing slopes at a relatively low altitude. In my garden, they are planted in a shaded bed to the north of my house where they get minimal sun and none at all in winter. Unfortunately, our winters are usually not cold enough so they usually don't floweer at all or in a very unsatisfactory way - unlike those shown in this photograph taken in Colorado (http://www.fs.fed.us/wildflowers/regions/rockymountain/WestElkScenicByway/images/erythronium-grandiflorum-lg.jpg).

Soil temperature would seem to be the key, then, but I can't say if your little sternbergias are too warm or too cool.

Chris - it seems to vary according to form (or 'species', if you prefer). Here S. greuteriana has been producing a succession of flowers over nearly 4 weeks. S. lutea angustifolia from Crete produced a second set of flowers - it usually does despite its virus infection. Last year S.sicula 'Arcadian Sun' also produced a second set of flowers - it didn't flower at all this year

Yes, the anthers are relatively large on Tony's (Melvyn's) plant but this does not seem to be a consistent feature - they are not so on my own plant, for example (posted somewhere above). Moreover, relative anther size does not seem to have been used previously as a basis for distinguishing species. I await with interest the BD's discussion - but I will take a lot of convincing that these plants should be distinguished botanically.
Title: Re: Sternbergia 2009

Perhaps not so much a question of "larger" anthers  but longer, and held differently at full maturity- which is a diagnostic feature in, for instance, narcissus.
The BD's other point is also a recognised diagnostic, which seems to have been overlooked thus far!

And all we're talking about here is the visible differences for us to visually discern the species.  They may be all kinds of different underneath, hence the differentiation into species by botanists.  Going to the alien analogy etc.... if someone looked liked us but had a completely different internal structure, it would be classified as a different species, even though visually it appeared the same on the outside.

Hristo, my best garden site for Sternbergia is this south facing wall. Close to this wall lutea, sicula and greuteriana flowering is reliable even after a cold and wet summer, but as little as 1 m from the wall you only get rich flowering after a warm summer. Another experience is that flowering is not so rich the first couple of years after planting. It seems they like to be undisturbed and get congested before real good flowering occurs.

But I have a problem with this site. A big oak (which I would like to keep) take more and more of the sun in this bed, so in near future I will have to find a new home for my Sternbergias. I have planed to make a new rock bed in the open garden, but unfortunately there is no wall. Instead I will make a warm place at the base of some big stones facing south.

To all Sternbergia friends: If you have some photos or description of such a bed, I will be very glad if you could post them as an inspiration. Thanks!

Maggi I can now confirm at 10.50pm that I have both subspecies

openfloweratnightii and closedfloweratnightii both from the same batch of seed.

I am now wondering if there is any significance in the way the leaves rotate on different plants. On some the leaf tips are turned clockwise and on others counterclockwise? This is clearly visible on different collections.

So would that mean you may eventually end with both openfloweratnightii and closedfloweratnightii with formas clockwiseiana and counterclockwiseiana?  Could you then give a varietal name to one of the night open ones as well?  

I think saddling it with an epithet like Sternbergia sicula ssp openfloweratnightii forma counterclockwiseiana 'Midnight Sun' might be a little rough though, even if that would be a cool name.  :o ;D  Then again, maybe someone will do so and I can sit back and let the royalty cheques roll in.  ;)

a couple of 'species' of sternbergia showing different flower shapes

Sternbergia lutea
Sternbergia sicula
Title: Re: Sternbergia 2009
Post by: Melvyn Jope on October 11, 2009, 09:38:28 PM
Another Sternbergia shape, this time a S. sicula from near Rethymno.
I have followed the same steps as Tony and have been looking at my Sternbergia at night and there is no consistency, some remain open others are closed. I wonder if it has anything to do with whether or not they have been pollinated. I cannot check on what I call S. greuteriana ( originally from Omalos) as mine finished flowering about a month ago.
 I was aware that Paul Wilkin was writing a paper as he came to see my plants and he mentioned that they would all be regarded as forms of S. lutea. I am not a botanist but when I see the morphology of my largest S. lutea and compare with S. greuteriana I think it requires some method of defining the various forms, perhaps as described by Rodger in his post on 25th September, at least we would then know what is being described.

This would be nice Melvyn but,  given the range of forms shown on the forum, I suspect the list of definitions  would be as long as my arm. The phrase "infinite variety" comes to mind.

Starting to flower what I have as S. angustifolia. [S. lutea x sicula].

I received these plants about 12 years ago, they never set seeds, which might indicate that it is an hybrid.

Oron - when it appears I would be interested to see the foliage on this plant. The plants I have under this name have leaves which are  intermediate between sicula & lutea in width & more-or-less upright. However plants are currently being distributed under this name in the UK with foliage much more like sicula - very narrow & almost prostrate.

By the way, my plants are self-sterile but can be pollinated by sicula.

Gerry thanks for your comment, i find it very intresting that it set seeds being pollinated with sicula, would never think about it...
as i remember the leaves are upright as you have described, i will post a photo when they appear.

Thanks Dirk - great pictures of Sternbergia in its habitat!

Here I have made the observation the larger (S. lutea) start to flower some weeks earlier than the smaller ones (S. sicula) -  and S. greuteriana shows it first bud recently -  they all have the same (or very similar) conditions in the open garden.

Title: Re: Sternbergia 2009
Post by: Gerry Webster on October 20, 2009, 05:10:28 PM
Fascinating to see the variation Hans. S. sicula 1 looks just like a large form of S. greuteriana while I've never seen a form of S. greuteriana that is quite like your plant.
It's very curious that 'Dodona Gold' doesn't flower for you - are you sure it's true to name?
Title: Re: Sternbergia 2009
Post by: Hans A. on October 20, 2009, 06:16:08 PM
Thanks Fred  - I knew you would like the double form specially ;D

Thanks Gerry,
this S. greuteriana is a form which was distributed by J. Amand in 1994 - it is still not open but i decided to post it as tomorrow the weather should be terribly bad. Depending the wheaterconditions I will take another shot. This flower is about half of the size of the smallest S. sicula (S.s.5).
Dodona Gold is from PC so it should be correct - I suppose it is my fault it does not want to flower as I always heard it would do fine also if it is planted in suboptimal conditions - it seems conditions where I planted it are too suboptimal ::)

Here some more pics I could take today. I realized one of the double Sternbergias flowered double - two flowers on one stalk.
As S. greuteriana is always of interest here some more pics which might show how tiny it is. The wheather was quite bad so I am glad it opened a bit with the little sunshine we had. (coin diameter 25,75mm)

Maggi you might be right, I checked the flowers and they have both - anthers and stigmas.

Dimitri: Your colchiciflora are outstanding! Many of us (including me) have problems with them. Often we do not see the flower, but in the spring a seedpod indicate that it has flowered below the soil surface.
The pink one on the last photo is that a meredana/colchicum montana or have you painted a St. colchiciflora? ;D

I have 2 clones of colchiciflora and both aren't from Turkey or Iran or Syria. Never saw them flowering under soil but read about this phenomenon in wild when the climate is so hot that flowers don't appeare outdoors. But in Europe the climate isn't hot at all!!! Why does it bloom under soil with you??? Poul, do you have an intention try to grow one of my colchiciflora clones at you?

The pink one is Merendera montana- you are right! They are so so similar by petal forms!!!! so I could not resist making their joint portrait! ;D

Oron,

It is real nice to see Clusiana in nature!

We have had a frost free November in Denmark and the St. lutea still flowers. This photo was taken in the last days of November.

I have another form of lutea in the open garden which are very late this year. As there still were no sign of them some weeks ago I thought they have been destroyed by the narcissus fly grub, as many of my others Sternbergia. I therefore decided to dig them up to kill the grubs to minimise future attach's. But the bulbs were all healthy! Apparently they had not had enough heat and dryness in the summer followed by some cooler weather to wake them up. I have to admit that they are not placed in the warmest part of the garden.
And as they normally has very few flowers, I decided to pot them, so I can give them a hot summer bake.
