Acceptable Oxalis

My experience is like Mike Mace's. Oxalis obtusa, especially the pink one
with grey leaves, appears in lots of pots. But the Oxalis obtusa I tried in
the ground in areas I thought it safe to do so, has disappeared. So perhaps
the Northern California experience is different than the Southern
California experience. Oxalis purpurea is the one that gets out of hand in
the ground here and Oxalis pes-caprae. Also interestingly my only attempt
to grow Oxalis inaequalis was a failure. There was one or two short lived
flowers and they were gone by the second year. So it sounds like I might
have been lucky if it produces bulbs by the thousands.
