Oxalis

Oxalis is the largest genus in the family Oxalidaceae and represents about 800 of the 900 species within the family. It is a large genus of flowering plants with over 550 species native to the tropical climates of South America and South Asia. Often referred to as Wood Sorrels, Oxalis are also known as False Shamrocks and a plethora of other common names. Of the Oxalis species in cultivation, Oxalis triangularis is the one most commonly cultivated as a houseplant.

Oxalis are not only excellent houseplants because they come in a range of colors and sizes, but also because they are so prolific. They are, in fact, SO prolific that they are considered to be weeds to gardeners and greenhouse growers worldwide. Many will go through a dormant phase in the wintertime if kept as a houseplant. A significant portion of the play may die and go into dormancy if not receiving enough light. Give a dose of fertilizer and more light and it’ll grow back.
