Crocus laevigatus from the SRGC 2008 seed ex opened on this sunny new years day, outside and unprotected
-
How perfect!
-
very nice to see
-
the first 'spring' crocus in showing colour here
Crocus concinnus - I got it from Jānis Rukāns! It grows in the Akseki region in Turkey and was known as one of the many 'isauricus' species. But the true isauricus is not growing there. (info on janis website)
-
mine just faded, it's very cold now and the flower doesn't last :-[
-
Today saw first two yellow buds of spring - C. ancyrensis, the typical variant. Temperature outside dramatically drops. In morning it was minus 2 C, at midday minus 5 outside and minus 2 in greenhouse, but now it lowers each hour and at this moment outside temperature dropped to minus 13.7 C. What will be in the morning? Last weather broadcast warned for minus 30 on Saturday. Tomorrow will try to reach nursery (there still are Muscari, Scilla, Ornithogalum collections) through snow-heaps formed by snowstorm during this day and promised for the rest of night. Oh, God... Must to cover everything. Global warming! Where you are?
Fortunately crocus etc. collections are in the new greenhouse only 100 m from living house, so covering will not be problematic.
-
Janis,
Courage to face these temperatures and protect the whole. This morning, how much did he do?
-
Early morning outside temperature today was minus 14 C, in greenhouse air temperature minus 9.5 but at pots bottom (between them) +0.2. Now all is covered by glasswool sheets, temperature at this moment in outside is minus 16 C and continue dropping. During the day the "warmest" was minus 13 C.
Covered were flowers of CC. hittiticus, ancyrensis, fibroannulatus, fauseri, korolkowii, alatavicus, some unidentified samples, may be some other species, too. Not remember full list. Of course in full bloom still were melantherus, laevigatus, aleppicus, boryi and some others. Flower buds were out in Sternbergia candida, and bloomed even 1 plant of Corydalis angustifolia - this one certainly will die.
-
Crocus laevigatus at midday today with a high temp of -9C (16F)
Same flower as shown open on Sunday when it was 45F(+6C).
I think these can take a lot of cold temp. swings
-
Pretty amazing the cold temp. these delicate flowers can withstand - good luck to you all!
-
Despite the cold the earliest Crocus are there, an alatavicus is already faded i didn't see it in flower :-\ waiting this week after another pot to bloom.
Crocus biflorus crewei
Crocus heuffelianus
Crocus korolkowii 'lucky number'
-
Crocus pelistericus
Crocus biflorus alexandri

Don't think that you have cold. This morning here was minus 23 C, at present became warmer "only" minus 15 C. During last night in greenhouse temperature dropped to minus 16, but at pot level under cover was +1 - so soil still is warm and heats plants. Hope all will be OK, although during last 4-5 years the minimum outside never felt below minus 20. :'(
According names - I think that better to use binominals (to regard subspecies as species). According DNA C. crewei belongs to different series and is quite distant from typical C. biflorus, as well as from C. alexandri in Tony Willis entry, following yours. On phylogenetic tree they all are quite distant, so no reason to keep them as subspecies of C. biflorus, only because of similar corm tunics. Then C. speciosus could be regarded as C. biflorus subsp. speciosus. ;D By the way - C. crewei belongs to Series Speciosi (according the new phylogenetic system) :o
As I joke - using of binominals instead of subsp. saves your time in writing as well as space on label ;D
Of course, to break old traditions are not easy. When I was young similar discussions was about name of C. kotschyanus. Then the common name of it was C. zonatus - easier to write, to pronounce etc. Who now use zonatus in nowadays? The same is about C. angustifolius - only some Russian botanists still keep the old name C. susianus, used for it in my youth. But it is your choice - most important is to understand about what is talk. But I recommend to follow progress.
It is reply to Tony's entry on Facebook, too.
-
I don't intent to achieve a coldness competition, you'll always win :D For our oceanic zone it's cold, i just remind a minus 17 when i was young. I guess we'll never endure such temperature in the future.
So simply Crocus crewei, 8cm label will be enough now ;D
For several years the east europe is having colder winter, south europe much snow and here mild and wet winter.

Few minutes ago my new Crocus book's page layout was forwarded to printing company. They promissed to finish printing during 2 weeks and then I will start despatching of book to all my sponsors and those who already sent orders. I want to remind that books format is A-4, size 568 pages and are included more than 1700 colour pictures covering 235 species recognised before 1st December, 2016. Books price (including postage) is 65,- Euro for Europe and 70,- Euro for out of Europe.

Very nice Steve,the cvijcii is very early mine are just through
-
Thanks Tony! This cvijicii is early for me. I have two other pots in frames which are only just noses. The cvijicii in flower is in my greenhouse which tends to warm up during the day -I need to move this and some other crocus into a coooler frame.
Crocus michelsonii -Two different forms -the first is from Turkmenistan, the second came from Janis -I am not sure of its initial provenance. These have also been grown too warm in the greenhouse!

There is no difference between populations from Iran and Turkmenistan - the same range of variability. I deliver open pollinated seedlings - so there can be "hybrids" between plants from various populations, but mostly just Iranians dominate, as at present I have only 3 acquisition numbers from Turkmenistan and much more from Iran..

Never heart about this hybrid, yes it was cold tonight, 0.7°c in the greenhouse and some of my orchids pots are frozen :-\
-
Wonderful Crocus' everybody !
Steve, your pictures are so tremendously, breathtakingly perfect that I am considering to stop taking pictures myself... ::) :-\ ;)

Some in flower today
Crocus vernus from Gargano,Italy
Crocus herbertii from Ulu Dag, Turkey
Crocus veluchensis from Mt Olympus,Greece
Crocus orphei from Mt Falakro,Greece
-
Lovely picture Tony.
Orphei is a real stunning crocus :o :o
-
I just have to repeat, nice crocuses that you show. And always new to me species like C. orphei. I have been at Falakron several times but always later.
Here it is below zero since one week and without a greenhouse I have to wait till the snow is melted.

In contrast to Steve's crocus with black anthers, here is Crocus chrysanthus 'Sunspot' with black stigma.
Elsewhere there was a discussion as to whether or not 'Sunspot' was still considered a cultivar of C. chrysanthus - I replied, quoting from this forum some time ago that : the late Marcus Harvey once wrote in error - and quickly retracted, that Crocus chrysanthus "Sunspot" was related to the newly named Crocus muglaensis.
Now Janis has also replied:
Not easy to give correct reply. According Bob Potterton (private communication during some of Early Spring Bulb meetings in UK) it comes from Gembos Yayla near Akseki in Turkey. I found there similar individuals, too. If it is so - then it belongs and must be named as cv of Crocus gembosii. In any case it is not C. chrysanthus - different from typical European C. chrysanthus by several features (as all Turkish so named C. chrysanthus), and Sunspot belongs to Turkish group of yellow flowering annulate crocuses.

Crocus x gotoburgensis first one to flower this year. My own hybrid
-
Super shots, Tony!
When I first saw this hybrid some years ago I was unsure as to whether I liked it or not - it is certainly very striking but I thought it a bit "odd". Now I have come to like it and I know that many of the F2 hybrids are even lovelier. Isn't it great that one can teach an old dog new tricks?!!
-
woow tony! Perhaps the best coloured crocus i've ever seen!!!
-
Maggi i think we are all allowed to change our minds on what we like. It is very variable and some are hardly distinguishable from Crocus scardicus but others are like this one.
I think I am still a year off flowering the f2 hybrids,something I said last year!
i have managed to cross a white C. pelistericus with C. scardicus and it will be interesting to see what they are like.
-
I'll be looking forward to seeing the first flowers - when they deign to arrive, Tony!
-
Crocus x gotoburgensis first one to flower this year. My own hybrid
Excellent! And quite typical F-1 generation seedling from this cross.
Janis
-
Crocus x gotoburgensis first one to flower this year. My own hybrid
Really a super Crocus Tony ! Respect !
-
Excuse my question. It is a hybrid between which Crocus and what other?
-
Fred, it is between C. scardicus and C. pelistericus
-
Thank you, Maggi. They can be seen in the bulb log of April 08, 2004
-
Fred, it is between C. scardicus and C. pelistericus
It does not seem to matter which is the seed parent or the pollen parent the offspring look much the same. I have mainly used C.pelistericus as the seed parent as I have more of them and so the pollen from one C. scardicus can be used on several flowers.

Crocus Malyi

Crocus korolkowii from Mongol tau Uzbekistan
Crocus suaveolens 'De Jager'
Crocus ushakiensis

A treat to see your crocus growing and opening in the sun , Ruben. Dark wet and generally horrible here in Aberdeen - I don't blame our plants for staying underground!

We've had our share of dark, cold and misty weather for a while now Maggi ! Keep hoping, the sun WILL return some day ! :D
It showed again starting yesterday and the first results are visible.
2 Crocus' that need to have their label changed... :-\
First what is now called Crocus gembosii 'Sunspot' I suppose, opening a first flower. (1-2-3)
I don't just love the black stigma but also the purplish/brown flower tube contrasting so nicely with the yellow flower ! 8)
and
second : Crocus ushakiensis (formerly C. chrysanthus 'Ushak Orange') also getting started, second flower already pushing through as well.

And again, Luc ... We are in the same country, and yet ... It only clears away since yesterday. We have not had more than an hour of sunshine today. There is still snow for at least one more day.
Like what, the climate, a few tens of kilometers away, may be very different.
-
Hi Frédéric - from what I see, you still are abt 150 km away and 3 or 400 m higher than I am.. :D
We had no snow at all here but 10 cm of ice on the gardenpond - still melting - but that doesn't deter the Crocus' ;)

From where comes yours "punctatus"? Can you picture anthers? Actually I would think about leucostylosus for white stigmatic branches. But too little details I can see.
-
Janis, its from my begin period- i got it out of a swap.
i will photograph the branches but i'm afraid it will take some days (forecast is rain and wind and no sun :-()
Is leucostylosus something that can happen with any species?

C. punctatus anthers have blackish basal lobes, leucostylosus - has white stigma, but such occasionally occur in other species, too. So check basal lobes, if they are blackish - name could be correct.
