That's hard to understand when the ground freezes so deeply in the upper Midwest, and these crocuses start growth in fall. Does the ground never thaw during the winter? Are they somehow in suspended animation? How can they survive? In milder, but still cold-winter, climates, repeated freezing and thawing are hard on low-elevation Mediterranean crocuses.>> Crocus goulimyi in a number of forms and colors has done well here outside for a number of years, both in raised beds and the garden. The foliage is trashed by the end of the winter - frequent ice and snow burns it back from the tips. However, this doesn't affect vigor at all. It builds up moderately by vegetative means. My favorite fall crocuses are C. tournefortii and boryi (and some lovely hybrids between them). Both tournefortii and the hybrids build up very rapidly in the ground and also set masses of seed which germinates in situ. Their color, ability to open in poor weather, extremely long flowering period, and lovely lolling stigmas make them unique. J.
