Oxalis regnellii var. triangularis

Oxalis leaves are palmate with 3 - 12 leaflets - often clover-like. Some species are invasive and considered to be weeds. Others make excellent ground cover or houseplants. Most are frost tender and suitable for greenhouses or conservatory in cooler climes. 'Oxalis triangularis' - commonly called 'false shamrock' - is a species of edible perennial plant endemic to Brazil. Oxalis triangularis is a non-invasive wood sorrel which, like other bulbs, has a dormancy period at the end of which the bulbs can be dug up, , bulbils removed and replanted to grow into new plants. The leaves of Oxalis triangularis react to light levels, opening in strong light (in the day) and closing at low light levels (at night). The small pinkish or white colored blooms are an attractive addition to the rich purple leaves, which are the star of the show. There is also the plain green type which look similar to a four leaf clover, minus a leaf. Oxalis regnellii var. triangularis bears purple foliage. It is often sold as a gift plant around St. Patrick's Day.
