This is responding to an old subject but the topic reappeared so I will add a thought. I work near Ring Mountain in Tiburon, and almost all the leaves of Calochortus tiburonensis show maroon streaking to some extent. all are smooth, but I have never seen bluish leaves as you had been led to expect from the glaucous description. I grow C obispoensis (archibald seed), and tiburonensis, umbellatus, luteus and argillosus(sp?) all from wild collected. I live in Vallejo, warmer and maybe a little less wet than Berkeley. I grow my plants with close to no fertilizer so they are very slow but have no problems with winter losses. C obispoensis is easier than these others. I think my C tiburonensis was planted in fall 2007 and I thought they would bloom this year, but no.
