Tony
Really love robertianus but it is not so keen on me. I lost most of mine last year after a good harvest the year before. There were just husks when I came to repot except for one and that has not yet appeared. I am hoping that I have some seedlings from my own plant a couple of years ago though it will be some time before the leaves show so fingers crossed
Also here is a nice pulchellus raised from your seed
-
What a sunday, 20 ° C in early November. :D :D
The last Crocus laevigatus in bloom. First, the Albus with the gold back outside. Through the many light not very yellow, later in the autumn, the buds are really golden.
This make also some spring flowering bulbs. Forms of Crocus sieberi also have a yellowish outside at early flowering, especially under cover.
The other is the dark form of Tony Goode.

Ian, the disappearing of robertianus can be great problem invaded many great collections in W Europe. It can be bulb mite, if I well understand symptoms - the nightmare of many bulb growers in districts with long mild weather. No real chemical usable for amateurs, hot water treatment very difficult but possible for crocuses. Fortunately here we have cold winters and quite short period in autumn and spring in which mite can develop. Temperatures in greenhouse are too high in summer and again it is not good for mite. One of great crocus-man almost stopped growing of crocuses in Germany as lost almost all collection.
What I can recommend - the first is sanitary. Always replant in fresh compost, always use fresh pot or sterilize used one in boiling water. To keep collection - always collect seeds, saw them in new pot, new compost. If your pots are plunged in sand - change the sand and sterilise bench before putting new sand on it. This could help but not always. One good way is to replant corms in new compost immediately after leaves die. Clean from old tissue, put in fresh soil and sterile/new pot. After that I keep most of them in greenhouse where temperature rise to +40 and even more in hot days. Of course some are brought outside - pelistericus, scardicus, scharojanii and few others.
I fortunately escaped this problem but always I'm replanting my crocuses with trembling heart. Some corms die every season but it is not more than 10-20 bulbs from several thousands of pots with 1-20 corms in each and even microscope didn't find any sign of mite, but I'm afraid, too, especially when I saw how this looks in Germany.

Janis thank you for your helpful comments I will add these to my list of critters not welcome. However as this was not widespread I think that in my case I may have allowed the pot to stay too wet after dormancy. I do repot most each year in fresh compost though I am beginning to believe that some do not like this or at least the way I am doing it . For example I hardly ever repot pelistericus and am now giving cvijicii the same treatment as this seems to do better when not disturbed

Janis,
Bulb mites are a big problem! It lives in big populations and they are difficult to fight.
For several years I had problems with narcis fly (small and big) in my snowdrops. I searched long time and find that VYDATE is 99.9% effective. They use Vydate in Israël where they breed narcissus.
I use vydate in the growing season of bulbs (narcis, crocus, galanthus...). Its works also good on bulb mites.
"Vydate® L is a broad-spectrum insecticide/nematicide for reliable systemic control of labeled above and below ground pests in many crops, including tomatoes, cucurbits and peppers.
It has shown effective, fast-acting control of aphids, mites, thrips, leafminers, weevils, leafhoppers and other yield-robbing pests across multiple life states. It also reduces nematode feeding, movement, reproduction and hatching. Vydate® L can be applied as a foliar spray at planting or via chemigation. Foliar applications can translocate downward to the root system, and soil applications can move upward through the roots throughout the plant canopy to protect both the root and canopy".
After the growing season i pick up all the bulbs. I use new soil and new pond baskets.
But i also use TOPSIN M.
I let the bulbs in a bath of this product and then the bulb is also protected when they are dormant.
Both product have got a good result.
I'm against the use of chemicals but sometimes its the only thing that rest to kill those pests.
-
Very nice plant that C. robertianus Tony ! Great that laevigatus Dirk and the next you wil recognise .... ;)
This weekend C cartwrightianus was stil in good condition. In the meanwhile the heavy rain has changed this situation...
-
Third time flowering now : Crocus veneris .
-
They use Vydate in Israël where they breed narcissus.
I use vydate in the growing season of bulbs (narcis, crocus, galanthus...). Its works also good on bulb mites.
Hi Ruben,
I looked through the information on Vydate. It seems to be highly toxic to all insects including nectar and pollen feeders, ie the pollinators. The prevention period for bees is 14 days. I wonder if the remnants of the active ingredient present in the plants afterwards may be sublethal for bees and contribute to the bee plague. Using in open field may be risky, in the greenhouse risk is lower.
-
Hi Jacek,
Its indeed toxic for bees and pollen feeders.
The narcisfly is atrracted by the smell of decaying leaves of Narcis, galanthus, leucojum... . They put there eggs ONLY in decaying leaves and not in fresh green leaves.
The leaf starts to die of a long time AFTER the flowering time of the snowdrops, narcissus, ... .
So i use Vydate begin April (depending on the season), medio april (for narcissus),... . So as you can see pollen feeders do not feed anymore with pollen because the flowers are allready disappeared. (an average of 1 month).
For that reason I can't harm bees and other very useful creatures!!
-
I'm very happy with this one from Janis : Crocus wattiorum :D :D
-
Unlike many of you I don't have much flowering in my garden after loads of rain here.
But here are some Crocus mazziaricus from the Athens area:
-
... and some hadriaticus from the Northern Peloponnese, not really showy on the last photo :-[:
-
...melantherus, a pure white laevigatus (019) and boryi (010):
-
not a Crocus, but also beautiful: Sternbergia sicula
-
Thomas,
to see very nicely always, Crocus and Sternbergia in the natural location.
-
Great to see them like that Thomas.
It seems that you are right on time ?
-
Pictures from this weekend ...
-
The beauty of these crocus is taking my breath away. What jewels of the flower world they are.
-
Wow Kris - mathewii is doing very well for you :o
Yes, I've been right in time - hadriaticus was in full flower, last of mazziaricus and first of melantherus were out on the northern mountains :D In the South hadriaticus and niveus were already over, only a few last flowers were out. And I was too early for cartwrightianus :-[
-
Very Nice pictures Thomas! Thanks for shearing. I hope to make this trip the coming years!
-
Crocus longiflorus Nebrodi (AH 9703) in flower.
-
After returning from Greece today was the first day with some sun and nice warm weather. So late autumn crocuses were in full bloom
Crocus laevigatus now is in full bloom. My favourite is Goldback, one of the latest between laevigatus. It is very variable species, on last two pictures forms got from Kurt Vickery (UK) and PELO-013 collected by me on Peloponesse during my first trip to Greece 6 years ago..
Janis

For Crocus ochroleucus it is a little too late for good pictures, but it is first moment when I can get them with nicely open flowers. As you can see typical form from wild has much wider flower segments than forms usually offered on trade. Dalton White is excellent selection from wild made by our forumist Oron Peri.
Crocus cambessedesii just now starts to reach peak of blooming. Here you can see variation in wild stock from Maliorca. It has one of smallest flowers between crocuses comparable in size only with Cretan Crocus pumilus.

Quite recently was discovered that Crocus macedonicus has much wider distribution in Greece than was supposed by me. I just saw pictures with meadows covered by it far to South from Vertisko ridge. Greek scientists found that it has different chromosome number than Crocus pallasii although regarded it only as C. pallasii.. Some similar crocus was found even near Athens but not seeing material isn’t possible to judge about its name.
On another 2 pictures you can see very beautiful crocus collected by me as C. mazziaricus in Turkey, but it certainly it is another one, most likely new species. Still research on its identity must be done. Sorry, I’m not mentioning locality even approximately yet.
Janis.

As last for today – 2 forms of Crocus cartwrightianus and 3 pictures of Crocus pumilus.

Hi Janis,
Lots of flowers showing for you there. C. cartwrightianus 'Purple Heart' is a stunner. The photo of this plant in your book turned me on to this species but I've not seen 'Purple Heart' listed in your catalogue. Is it possible that Liga may list it in future?
Regards.
-
Having been away for 2 weeks, I've missed quite a lot of flowers. However, the sights we found in the Peloponnese more than made up for that and a few plants are still pushing up flowers to greet me on my return.
Crocus tournefortii is a favourite for it's delicately coloured petals and brightly contrasting stigma, but C. ochroleucus has a simple beauty too.

Greetings Ibrahim with returning to Forum. Your entries allways are very inspiring!
Here weather broadcast changed and coming frost disappear somewhere - may be it turned to USA? Dramatic situation there, but here still bloom last crocuses. Today Liga cleaned pots and boxes from died flowers, but I maid few pictures.
Most valuable plant is beautiful aquisition of Crocus cancellatus from Syria, originally collected by my friend Arnis Seisums before civil war there started.
Then Crocus cartwrightianus from EP and as last
Crocus tournefortii from Rhodos Island
-
Hi Janis, Thank you very much for nice compliments.
Here is a very common autumn crocus. I found this where I was looking for a new described one C. lydius!
C. pulchellus from western part of Tr.
-
Superb plants Ibrahim and Janis!!
Here some pictures from the garden taken today, first some fine C.cambessedesii and two C.mathewii, the second one is a seedling, not the very similar looking C.m.'Dream Dancer' (over or destroyed by heavy rain here).
-
Hans, that yellow back C.cambessedesii is simply stunning!
-
Hi Hans,
I agree with Matt, your yellow C. cambessedessii is perfect :o
It seems you are very good grower and C. cambessedessii looks very happy with you!
İbrahim

Oh, Hans,
This cambessedesii with yellow back is really mouth watering! I really envy you for it! But simply blue is excellent, too.

C. niveus from Dirk
C. ligusticus Dirk
To see Ibrahim, nicely you again here. :D
The Crocus ligusticus have developed really well.
-
Stunning Crocusses Ibrahim! It's Always nice to see the plants in their natural habit!
Hans, you're yellow cambessedesii yellow back is so gorgeous!
Janis, i very much like you're cancellatus from syria!
Today i saw the first appearance of noses from Crocus biflorus nubigena, crocus michelsonii, crocus alatavicus, ... . ;D

Excellent pictures Ibrahim, especially pamphylicus.
C. pallasii from Labranda is the best form of pallasii known to me, but I have only 3 corms from there and between those are not whites. I didn't visit this place at blooming time of pallasii, all my specimens are collected in summer when crocuses are out of bloom.
Janis.

Thanks for sharing this wonderful pictures Ibrahim . 8)

Ibrahim, it is a real stunner :o
Here Crocus finally start to flower, a couple of weeks later than usual.
First is C. ochroleucus 'Dalton White' which is a pure albino form of this species.
-
Oron,
I never had sucess with Cr. ochroleucus. Perhaps kept it too moist?
Here are recent pictures (November 2014) of 3 Crocus species from Greece.
First 3 Crocus robertianus from Central Greece.
-
Next 5 images are Crocus mazziaricus from Central Greece, growing in low altitude (300 m) and facing South. It is growing in soil pockets in very rocky terrain.
George
-
Three images from a different location, about 30 km away.
They are not Crocus mazziaricus They are Crocus macedonicus, identification made by Janis.Also
-
Please let me correct:
The last 3 images, 0107, 0110 and 0120 are from a different location, about 30 km away.
They are nor Crocus mazziaricus! They are Crocus macedonicus, identification made by Janis.
Growing in turf, facing North and NE at 500 m.

Wecome to this forum George ! Nice to see those pictures from the wild !
Here Crocus hyemalis is stil in flower.
-
George,
It is very nice to see plants in wild. Specially this C. macedonicus! According to my pallasii forms your C. macedonicus have very nice prominent and longer styles. Thank you so much for showing us these beauties.
İbrahim
-
Hi Kris,
Your Crocus hyemalis looks very happy :)

And my eastern cancellatus with big white flowers which is not common for subsp. damascenus.
C. cancellatus subsp. damascenus Diyarbakır East Tr.
C. nerimaniae from SW. Tr.
The C. nerimaniae is stunning, Ibrahim ! :o :o Wonderful blue !
-
Ibrahim,
I have seen some styles being longer than anthers. I do not know whether this feature may depend on the age of the flower. As the flower ages, can the style keep elongating?
Does anyone know?
Following are 5 more images of Crocus macedonicus from other locations in Central Greece, about 60-100 Km away.

Yes, I quite agree with Luc :) Your C. pallasii dispataceus is fantastic, Oron :o :D
-
New Crocus species in flower today
Excellent, Oron!
It seems that I will have no more new flowers this autumn.
Today we had sun but temperature didn't rise even in greenhouse and flowers remained closed.
Janis
-
Thanks every one
There are many more to flower during the next three weeks.
-
A transitional period at the crocusses. Still to early for the early winter flowering types (but allready a lot of noses) and the autumn flowering crocusses or over here in Belgium.
Except for a cross between oreocreticus x hadriaticus. This one is flowering allready more than one month. 14 degrees today here and you can smell this crocus from afar.
-
My nose is just imagining that pleasure, Ruben :)
The high temperatures being experienced in some places are quite a surprise. I quess the N. Americans are suffering instead with all that snow. :-X Strange times we live in.
-
Crocus pulchellus Mt Chortiatis Greece
-
Two unusual Crocus boryi near Katafygio Greece
-
Crocus biflorus ssp. melantherus (a late form) from Greece. This one is marked heavy with purple stripes.
-
melantherus that also seems to struggle to flower
-
Crocus laevigatus pumilus (note slugs love it :-\)
-
I find the arrow-shaped anthers with that fabulous white pollen to be just fascinating.
But yes, I know , I find that with everything about Crocus . Such colours, such exquisite markings , such elaborate styles - such variable, wonderful flowers - and that's not even mentioning the corm tunics, or.. or.. or ....... !
-
Crocus melantherus photographed today
-
I very much like that form of Crocus biflorus ssp. melantherus Arthur. I haven't grow any forms of melantherus with dots.
-
Ruben
They appear to be in the minority in the field.
I like these very much and also alatavicus that can have outstanding stippling.
-
I agree Arthur!
Alatavicus is just above ground now. The first frost last night so i hope the blooms will be slow down.
I will post pics when flowering.
-
Mainly whites at the moment but some others as well
C. veneris
C. cancellatus cancellatus - Golan Heights
C. serotinus serotinus
Crocus boryi
-
others Ex Peloponnese
C. niveus
C. goulymii
C goulymii 'Mani White'
-
Beautiful Oron, I envy your climate. Here, any Crocuses outside are quickly decimated by wind and rain.
-
David,
While we are here a stormy weather starts and will last for about 48 hours, we will talk again after that... ;)
-
more whites
C. aleppicus - coastal form
C. aleppicus - Mt Hermon
C. ochroleucus 'Dalton Albus'
-
melantherus that also seems to struggle to flower
Even struggling it's a very nice one Yann !
-
Nice bath Oron! aleppicus is wonderful :P
Arthur did you repotted your crocus in the deep pots?
-
Yann
I had repotted most of my Crocus before the Kent Show. I lost a lot of Crocus last year, but curiously both melantherus and alatavicus did very well.
The pots have been used for several single bulbs where I think they will benefit from the greater depth.
-
This Crocus laevigatus 'Fontenayi' has been "flowering" for about a week now, but today was the first day that we have enough sun to encourage the flowers to open. I love the wide variation you find in this species, from palest, unmarked flowers to these dark beauties.
-
New Crocus in flower at the moment;
Crocus aleppicus 'White Throat', a form lacking the yellow throat.
Crocus hermoneus ssp palaestinus
Crocus cancellatus lycius
-
:o after a foggy day on the road i discover these beauties. aleppicus is on my Christmas list!
-
beautiful crocuses Oron,a delight to see.
My last for November,a Crocus pelistericus which should be flowering in March/April

Good grief - a C. pelistericus flowering in November - astonishing!
Have there been any nuclear leaks in your area lately, Tony? :o ::) ;)
