False Shamrock

Description:

Oxalis triangularis, commonly called False Shamrock, is a species of edible perennial plant in the Oxalidaceae family. It is endemic to Brazil.[1] This woodsorrel is typically grown as a houseplant but can be grown outside in USDA climate zones 8a-11, preferably in light shade. The subspecies O. triangularis subsp. papilionacea, in particular its cultivar 'Triangularis', is highly popular as a pot plant and known as Love Plant, Purple Shamrock,[2] or (like many relatives) "sourgrass".[3] They require bright or direct sunlight supplemented with a cool indoor temperature of ~15 degrees celsius (~60 degrees Fahrenheit). They can tolerate higher indoor temperatures but will go into dormancy prematurely and/or begin to take on a "tired" appearance if temperatures go above 27 degrees celsius (~80 degrees Fahrenheit) for prolonged periods of time. Use average potting soil with good drainage and allow the surface soil to dry out between waterings. Mature False Shamrock plants are cut back to the soil every 3–5 years in early summer or during the domancy period. Young plants are cut back to the soil every year in early summer or during the dormancy period, until they reach maturity.
