I have a small collection of rhizomatous South American oxalis. Of them, three are good doers: 'Ione Hecker', 'Gwen McBride', and 'Ute'. The others, some hybrids, some species, are not doing as well. They are somewhat tricky to grow; I think our winter rainfall is a big problem for them. Volcanic pumice seems to be a good choice for a growing medium, either neat or laced with a good potting soil. They seem to have gone out of fashion somewhat; the RHS Plantfinder lists relatively few sources, and a number of cultivars are no longer listed. In North America, the single best source seems to be Rick Lupp's Mt. Tahoma nursery, though a number of other nurseries offer a few cultivars. The labels for my collection became separated from the plants at one point and I'm still trying to figure out which is which. I've scoured the web for pictures, which has helped me identify 'Gwen McBride', but in doing so I noticed that more than a few picturs of this class of plant were incorrectly identified.
