Crocus year 2022
Robert:
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
Janis Ruksans:
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
Janis Ruksans:
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.
