Yesterday took off winter cover from greenhouse beds. Today the first job was cleaning of plants from old flowers - some melantherus and laevigatus were covered when they still were in bloom. Fusarium nivale and penicillium on old flowers is very dangerous as can go down to corms. A lot of crocuses showed flower buds. Here few pictures - all in closed buds due lacking of sun. Outside all the day was snowing.

Janis, what has been the lowest temperatures in your greenhouses and does the soil ever totally freeze?

Janis, what has been the lowest temperatures in your greenhouses and does the soil ever totally freeze?
This winter we had for 1 night minus 23 C outside. Below cover temperature didn't fall below -2 at top of pots and +2 C at bottom. Soil in pots were frozen for some time, that it was impossible to pick out labels. Then I covered with 3 layers of night-frost protection film (white, thickest variant - 50g/sq.m, thinner is not ussable). The price here for 100 m long, 1.6 m wide roll was ~70,- Eu.

Leena,
In the U.S.A Eliot Coleman wrote a book called the “The Winter Harvest Handbook”. The book discusses how Mr. Coleman grows vegetables during the wintertime in Harborside, Maine using unheated poly-tunnel greenhouses and floating row cover. Most likely you are already aware of these cultivation techniques. Based on photographs I have seen of winter vegetable production in Norway, and the recent postings by Mr. Ruksans these general techniques are well established throughout Europe for use with both vegetables as well as ornamental plants. From the best I can determine, from my home in sunny wintertime warm California; these techniques work extremely well in cold climates. The information in this book might be helpful to other Formists growing containerized or borderline hardy species in winter cold climates.

Crocus michelsonii from Iran
-
On Monday all was under deep, deep snow. On picture my greenhouse's outside. Now it is slowly thawing. But yesterday was some lighter weather and some crocuses even opened flowers. On the last picture - bad result after overlooked died flower - the rot from flower segments came to leaves and by them down to corm.

Some more pictures from last few days
between those two acquisitions of normally late autumn blooming Crocus laevigatus which started blooming below cover and normally blooms now - from Evia Island and labeled as 'Dark Form'.
My famous pink Crocus alatavicus still in tight bud
New species from Iran shows its variability
and another Iranian - close to Crocus cf. iranicus 18IRS-054 from so named Anemone field
-
And some more
Such remnants of cataphylls in autumn blooming crocuses appears quite often and must be removed to make leaves free and to avoid possible fungal disease on dead tissues going farther in leaves and finally corm
Even only in buds C. cyprius is already very pretty
Crocus demirizianus own gathering needs sun to open
as well as C. fibroannulatus which started blooming even before winter cover was off
Usually all stocks of C. hittiticus blooms in winter - December/January. This season one stock started in November, but all others do this only now.
-
A little sun and few degrees over zero - all what need my crocuses for full bloom.
On the first two pictures pot with Crocus gembosii selection 21-07 in greenhouse and 2 hours later on my kitchen's windowsill
and some others

Thanks for sharing so many beautiful pictures, the ones showing diseases are very helpful.
Very pleased to see Crocus rhodensis flowering here, they’re different but both stunning.

Crocus olivieri ‘chios’ is quite uniform yellow, I liked the shadows of the setting sun.
[attachimg=3]
This Crocus, some chrysanthus cultivar? (public green), stood out because of the blackish edges. Others around don’t show it.

Not long ago Turkish botanists rediscovered true locality of Crocus paschei and found that it is identical with Crocus adanensis - its variability is the same as in adanensis. See https://dergipark.org.tr/tr/download/article-file/1781924
I can agree, really the single easy observable difference between both was throat colour. See attached pictures. So now name C. paschei is going into synonyms of C. adanensis.

Sun changes to clouds and cold wind, there are short moments when flowers try to open but soon closes again.

Totally amazing series of fantastic Crocus' Janis !!
I don't know why ;D, but for some reason C. youngiorum is by far my favourite !! 8) 8) 8)

Thanks, Luc!
Today seedlings (my own and Pilgrim from Dambrauskas) and general view in afternoon
-
Very beautiful Crocuses, the overview is impressive.
Crocus yalovensis is flowering here.
-
The first flowering Crocus in my collection this year (slightly confused or just impatient?)
C. damascenus BATM-351
-
That was early!
Good idea with the marking on both pot and label. I struggle often with birds removing labels.
What kind of ink do you use for the pot marking?
Poul
-
Hi Poul, well spotted
With me it isn't birds but small children who sometimes like to walk off with labels...
I use 'Edding white paint markers', they do the job very well. So well I have to scrape it off with a knive to remove it...

August IRG: We are delighted to present a new Crocus species described from Northern Macedonia by the team of Dr Jānis Rukšāns, from Latvia and Dr Dimitri Zubov, from Ukraine. Jānis says he is transplanting crocuses every day, but the first ones are already starting to bloom.
Second article this month is from the Scot, Connor Smith, about his workplace, the Utrecht Botanic Garden, which is rightly famous for its innovative rock gardens.

Yesterday it was a 'big day' here because the summer dry crocusses got their first watering. The autumn is in the air now and if I can feel it I bet so can the crocusses. I figured it must be the right timing then...
Anyone else who has had the same yearly pleasure?

Ian Young was out on the 1st of September - giving his bulb-house plants their first "storm" of the season - as he always does. For some in warmer areas, the storm may need to begin a little later for some fritillaries, for instance.
-
I bet he was Maggi ;D
Except for one or two crocusses poking their tips through the gravel there isn't much happening above ground yet. But I'm sure the first water will induce growth and before we know it we can admire the first flowers (or so I hope at least).

For Crocus Group members.
The UK Seed exchange list is now available. Crocus Group members can email me via crocusgroup at hotmail.co.uk if you wish to receive a list of seed and corms available.

Just two days ago there was nothing to be seen yet but then this evening when I visited the garden there they were, the first C. vallicola flowers just in the process of closing it's petals in the setting evening sun!
-
The sun is shining today (and so are some crocuses) ;D
-
The 1st picture is the 'ordinary' C. armeniensis
The 2nd picture is C. armeniensis 'Goris'
And the 3rd are both in comparison (Goris on the right)
Assuming the stamen of the left one might be underdeveloped I leave the conclusions to whomever likes to make any :D

Found some time visiting the botanical garden Munich today.. these Crocus cancellatus cancellatus must have liked this season, blooming as prolifically as I‘ve ever seen in this spot.

Test ( using Yann's pix from FB. ) I think it was only a temporary "blip", Yann.

thanks Maggi, yes i also think. Will try later in the evening to post other photos.

Today Crocus hittiticus opened after moving it to a warmer place. One of the flowers has some extra’s, the small one is normal. They’re from the same corm that was planted this year. Otherwise they look fine.
Is this ‘usual’?
