Oxalis triangularis

I never had any trouble with O. triangularis in Tucson. We shall see how it handles my small shady corner in Yuma!

Interestingly, it was perfectly hardy in Denton in north-central Texas, where it would freeze solid. The only problem was the fungus that would disfigure the leaves from midsummer on until frost.

Hello Leo,
Your experience with Oxalis
triangularis is not at all mine. Somehow I lost the plant
during my move to Portugal, although not completely, there
was a purple leaf in the pot of another plant.  Like
Mary Sue wrote, it hardly ever goes dormant and then
sometimes it does. When it dries down naturally the rhizomes
have always re-sprouted easily with me but they can die from
desiccation if kept dry for too long. It may only have a
very short dormancy naturally. I suppose it might die if
dried off before it is ready to go dormant by itself. Under
my growing conditions in Germany I never found it sensitive
to heat but of course it is not the heat of Arizona.

Bye for today

Uli
