>> I would love to hear Mike's success with planting Oxalis in the ground. Alas, the news is not good. When I first got my Oxalis bulbs from Michael Vassar, I noticed that a lot of them (especially the Oxalis obtusa varieties) produced copious offsets. So I decided to try some of the extras in the ground. I did it in two locations: A flat, well drained area with low competition from other plants; and a rockery area in which I could slip the bulbs between stones. Both locations do not get summer water. In both areas, the bulbs bloomed well the first year, but faded away over the next couple of years. Meanwhile, the ones in the pots continued to reproduce. I don't know why the ones in ground failed. Maybe they just don't like the local soil (which is heavy clay). I also know that the local mice love to dig them up and eat them. But they could not have dug up the bulbs that were between rocks. So I have a mystery. People who think all Oxalis are invasive haven't tried to grow them in the ground. Mike San Jose, CA
