Hi Nhu, Thanks for that info, I wondered about whether the presence on serpentine in the wild was more about tolerance than preference. When you say "good well-draining mix", what do you mean precisely? I have seen suggestions involving coarse sand, clay, peat moss, leaf compost, etc. I'm hesitant to use pest moss based on previous experience, but other than that I'm not sure what makes a good mix. Here in western Washington we have plenty of acidic clay-based and glacial till soils, and of course the full array of substrates available to nursery suppliers. What did you use in your pots in Northern California? Regarding the Calochortus, I think another problem may have been that I had the pot on a south facing wall in the summer here, where it got cooked. I'll keep my new bulbs cooler during their dormancy and see how that goes.
