Oxalis obtusa

Oxalis obtusa is a small bulbous wood sorrel from South Africa's winter-rainfall Cape, with flowers in pink, salmon or yellow tones in late winter and spring. It grows through the cool, wet winter and spends the hot, dry summer as a dormant bulb. Copying that cycle is the key to keeping it.

Where it grows wild

It grows in fynbos, renosterveld and karroid scrub on sandy, loamy or stony ground, in open sunny patches between shrubs. This is inferred from the genus in the Cape.

Mostly lowlands to lower mountain slopes. Few records carry elevations.
