Oxalis triangularis, commonly called false shamrock, is a species of perennial plant in the family Oxalidaceae. It is native to several countries in southern South America. This woodsorrel is typically grown as a houseplant but can be grown outside in USDA climate zones 8a–11, preferably in light shade
Oxalis triangularis is a PERENNIAL growing to 0.2 m (0ft 8in) at a medium rate.
It is hardy to zone (UK) 9 and is frost tender. It is in leaf from June to October, in flower from June to September. The species is hermaphrodite (has both male and female organs) and is pollinated by Insects.
Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers dry or moist soil. The plant can tolerates strong winds but not maritime exposure.

Landscape Uses:Container, Ground cover, Rock garden, Specimen. Easily grown in a sandy soil in a warm dry position in sun or light shade[1, 200]. Grows well in a dry shady corner. Plants are not very cold-hardy in Britain, tolerating temperatures down to about -3°c. Given a suitable position, it should succeed outdoors at least in the mildest parts of the country[K]. It should be possible to grow it even in the colder areas by digging up the bulbs in the autumn after the top growth has been cut down by frosts, storing them in a cool but frost-free place and replanting them in mid to late spring[K]. There are two main forms of this plant, ssp triangularis has smaller, green leaves and is, in our experience, slightly the hardier of the two. Ssp papilionacea has larger, dark purple leaves and is considered the more ornamental[K]. Special Features:Attractive foliage.
