Oxalis tenuifolia

A winter-growing bulbous Oxalis from the lowlands of the southwestern Western Cape, common around Cape Town, Stellenbosch and Paarl. It grows and flowers in the cool, wet winter and dies back to its bulb for the hot, dry summer. Growers succeed by copying that cycle: cool and bright while in leaf, dry while dormant.
