Mary Sue wrote asking about what kind of nighttime temperatures would be suitable to help Tecophilaea cyanocrocus to flower. Mine have flowered well in the bulb frames for many years now. I just repotted them and will have some on my surplus list. While dormant, they are probably fairly cool down in the soil (the pots and plunged to the rim in sand), and the nights here are almost always in the mid-50s F in summer. I think in nature (though it's hard to know from the single documented population that survives), the area where it grows has similarly cool nights. I've stayed in a village in the area and had to use a thick blanket even in midsummer. One think that I believe benefits these plants is ample water in their early growing season. They are apparently snowmelt lovers in nature. Some of mine did not flower as well or set as much seed this year as they usually do, although the bulbs appear healthy. I think this was because I was gone in January when we had a long dry spell, when I would have watered them if I'd been here. Jane McGary Northwestern Oregon, USA
