Oxalis ambigua

A small bulbous Oxalis from the winter-rainfall Namaqualand region of South Africa, where it grows through the cool, wet months and sits dormant underground through a long, scorching dry summer. Treat it as a winter grower: water from autumn to spring in strong light and keep the pot completely dry in summer.

Where it grows wild

Recorded across the Namaqualand uplands and plains in the Succulent Karoo, where small Oxalis bulbs grow in open sandy or gravelly ground among low shrubs. Species-level habitat detail is thin; this is inferred from the record locations and the genus in this region.

The climate sites sit at about 340 to 1,240 m, most near 360 to 710 m; few records carry their own elevation.
