Oxalis triangularis, commonly called false shamrock, is a species of edible 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.

The deep maroon leaves are trifoliate, like species in the clover genus Trifolium which are commonly called shamrock, hence the name “false shamrock”.
An interesting feature is that the leaves close like an umbrella at night (See the timelapse video below) or when disturbed.
The white or pale pink five-petalled flowers also close at night.
