Oxalis regnellii makes low mounds from June to October, with mostly five-petaled flowers on three- and sometimes four-leafed plants. This South African and South American native takes partial shade and stands hot, humid summers in full sun.
Use it as a shoes-and-socks planting around larger bulbs and perennials, or in patio planters indoors or out. Top sized 4/6 cm bulbs and tubers; plant 10 per sq. ft. Hardy in zones 7-10.
