All the more interesting since in my experience with T. grandiflorum, the rhizomes are generally situated in a quite shallow position…often just under the layer of organic duff. Hence, locations that don’t dry out quickly AND extra care in watering pots would seem to be called for…. Carlo Carlo A.

I too lost T. chloropetalum. Unlike John, I had the best luck with direct seeding plants where I thought they would grow well. I grew some in pots, but lost them in subsequent years but that may have been because I didn't keep watering them all summer, even when they were dormant. If you have looked at the thickened rhizome they retreat to in our dry summers you wonder how they survive since it isn't very substantial. Going into a third year of drought we still saw plants this year on our hikes in the wild, but not nearly as many as in previous years and both the bloom season and leaf season was much shorter than usual. I don't know if we'd see a come back with a more normal winter if and when we get one, but even in these past three years of drought we got much more rain than San Diego. And as John Wickham noted for T. chloropetalum, we have cool summer temperatures and a lot of fog/high clouds. You find the most plants of Trillium ovatum in places that are shady and are late to dry out. This year however I expect some of those places are already very dry. > > Andrew and I have shared plants in the past and found that what was happy in his part of California wasn't always happy in my part of the state and the same for him. > > Mary Sue > > _______________________________________________ > pbs mailing list > pbs@lists.ibiblio.org > http://pacificbulbsociety.org/list.php > http://pacificbulbsociety.org/pbswiki/ _______________________________________________ pbs mailing list pbs@lists.ibiblio.org http://pacificbulbsociety.org/list.php http://pacificbulbsociety.org/pbswiki/
