I get the sense that I. namchabarwensis is sensitive to how cool the nights are during the summer. To most people in the U.S. who have never visited the Bay Area, they have no idea how much it cools down there at night right through July and August. I have killed this species three summers in row now. [Does that mean I can now stop trying to grow it?] They do fine in the spring and fall here in Southern Calif. (BTW, for those who grow fruit trees, I believe that the Bay Area is the only place in the entire U.S. where you can successfully grow and fruit both orange trees and cherry trees simultaneously in the same location, if that gives you an idea of the Bay Area's climate.) This makes me very curious about the climate in that canyon (Tsangpo Gorge), purportedly the largest/deepest in the world and very recently (re-)discovered. ["The canyon has a length of about 150 miles as the gorge bends around Mount Namcha Barwa (7756 m) and cuts its way through the eastern Himalayan range. Its waters drop from 3,000 m near Pe to about 300 m at the end of the gorge. "] Sounds like an amazing place to try visiting one day (if they don't dam it first). --Lee Poulsen Pasadena, California, USDA Zone 10a David Ehrlich wrote: > Carlo -- > I can't understand why your plant doesn't care for warm weather. I've only had mine for a few months; it is flourishing, growing large and blooming profusely in Bay Area weather (warm dry days, cool moist nights). I have it in a sunny position, but I originally intended it for a shady place, where it will go soon. > > David Ehrlich > _______________________________________________ > pbs mailing list > pbs@lists.ibiblio.org > http://www.pacificbulbsociety.org/list.php > http://pacificbulbsociety.org/pbswiki/ > >
