This may be an obscure one but here goes: Season after season these bulbs survive, but they aren't terribly robust (just a single blade) and they don't ever bloom. It's been that way when they are planted in the ground and when planted in pots. This year they were in partial shade in a mix of sand, peat, perlite and some other organics. Any idea how to improve performance? I am in LA and C. greenei's range in the far north of California into Oregon (http://calflora.org/cgi-bin/species_query.cgi/…). It's been suggested that I might want to mimic a cold winter. How would I do this - eg, is it as simply as putting the pot in my refrigerator for a couple of months over the winter? Any other particular requirements compared to other California Calochortuses (most of which are doing fine here). I think they are from grassy slopes on serpentine - conditions I can't exactly duplicate. Does it particularly need soil with more organics, more sand ...? How about sun? Moisture amounts/timing? Thanks for whatever you can offer. Chris.
