Oxalis arenaria

A central Chilean Oxalis of sunny matorral and sandy slopes, from the coast to the Andean foothills around Santiago. The climate is strongly Mediterranean, with a short wet winter and a long, hot, nearly rainless summer. Treat it like other Chilean bulbous Oxalis: grow it in the cool, bright months and keep it dry over summer.

Where it grows wild

It grows on open sandy or stony ground in matorral and dry grassland, mainly in full sun. The habitat is inferred from the name, the record sites and related Chilean Oxalis.

Recorded at 70–1387 m (median 810 m), from the coastal range up to the lower Andean foothills.
