Crocus goulimyi in the typical form and in a white form have been easy growers in this garden for years. I wonder if the problem in Jane's location is not so much the winter cold as the summer cool. Many eastern North American woody plants hardy into the far north do poorly in much milder English winters, and the consensus seems to be that it's because of the relatively cool summers. > I think that all commercial stock of C. medius is virus-infected, so it would > have to be grown from seed (does anybody have some?). I've had Crocus medius from several sources many times over the last thirty-five years; I've never known these plants to set seed. So if anyone knows of a seed source, I'm interested, too. Several posts have had good things to say about Crocus laevigatus. I have only a few of these, and they are in an unheated frame. Evidently they are very tough: last year, they were in full bloom before the onset of a six-week freeze-up. The flowers went glassy during the freeze. Once things thawed out, the old flowers collapsed, but were replaced by new ones in about a week. One nagging failure here: the plant sold under the name Crocus cartwrightianus albus. This plant, whatever it is, is the touchiest crocus I've ever had. Newly planted corms rot or, it they don't rot immediately, rot as soon as the ground freezes. Actually, it's not the corms which rot: it's the new sprout, which rots near its connection to the corm. I've never been able to keep these alive for more than a few weeks, although even rotting sprouts will sometimes mature flowers. Does anyone know what this plant is? Is it really a white form of Crocus cartwrightianus? What is the secret to growing it?
