Gardeners' Notes:

Positive jkom51 On Feb 4, 2006, jkom51 from Oakland, CA (Zone 9b) wrote:

Unlike its invasive relative oxalis pes-caprae, O.siliquosa is a beautiful, well-behaved plant whose unusual foliage color both brightens up a shaded spot and really sets off other plants. It is a natural for combining with coleus, magilla, plectranthus or clivia. It can take sun, but will stay a more chartreuse-green or yellow. Even here in coastal Northern CA, it seems to be the winter chill that brings out the warm, rosy shading to the leaves. I've had this for three years in the garden, and it has never seeded itself elsewhere. It spreads itself out, but is easy to control just by clipping or pulling off stems.
