I'm still probably over fond of the South American Oxalis and the (too) many hybrids. I grow them in pots outside, generally covered in winter, uncovered in spring. Grown that way the stems remain very short and both the leaves and flowers sit almost on the ground. I don't know the parentage of this particular hybrid but I suspect it is O. laciniata x enneaphylla.
As the summer proceeds I tend to move them into partial shade.
