Definition

Hypoxis hemerocallidea (Hypoxis rooperi) commonly known as African potato, African star grass, Bantu Tulip, Papa Silvestre Africana, and Pomme de Terre Sauvage d’Afrique, South African Star Grass and Sterretjie is a medicinal plant in the Hypoxidaceae family. The plant has no relationship with the potatoes you’re probably most familiar with. It’s actually part of the lily family. The plant is native to southern Africa from South Africa as far north as Mozambique + Zimbabwe. This plant is the best known member of this genus. Its most common name is the African wild potato. It is a hardy very attractive drought and frost tolerant deciduous geophyte that is extremely easy to grow which is an asset to any landscape or garden. It grows well in most soil types in full sun to partial shade where it flowers freely throughout summer.

The name Hypoxis was given by Linnaeus in 1759and was derived from the Greek words hypo (below) and oxy (meaning sharp), in reference to the ovary which is pointed at the base. The specific name hemerocallidea is derived from the Greek hemera (a day) and kallos (beauty), presumably referring to the flowers which are short-lived and resemble the day lily Hemerocallis. African potato has been used as a traditional medicine for centuries. It is a household name in South Africa and probably the best known multi plant in the country. The African potato has even been recommended by a former Minister of Health for inclusion in the daily diet of HIV patients.
