Has anyone out there who gardens on the east coast of North America had long term success with either Oxalis adenophylla or O. enneaphylla as garden plants? I've tried O. adenophylla, and it does not seem to be very heat tolerant. If you are growing these plants successfully, please post some advice. I've sent this post also to Alpine-L. Jim McKenney Montgomery County, Maryland, USA, USDA zone 7, where some of the Mexican Oxalis are right at home.
