False Shamrock Overview

Oxalis triangularis is a bulbous perennial in the wood sorrel family, Oxalidaceae. It is deciduous and goes dormant in the winter, with the foliage dying back and regrowing in the spring. It grows best in partial shade and moist, well-draining soil. The leaves of this plant are very distinctive, they are palmately divided into 3 leaflets which are triangular in shape and coloured green. Flowers are white-pink and starry in appearance, they appear from summer-autumn. This species is commonly grown as a houseplant, particularly the subspecies Oxalis triangularis subsp. papilionacea which produces beautiful purple foliage.
