Streptocarpus goetzeanus is a small lithophytic subshrub from the Uluguru Mountains of Tanzania, grown as a houseplant for its violet and white flowers. It is notoriously hard to keep, as it needs the humid, shaded, mossy-rock conditions of its native cloud forest.

About
Streptocarpus goetzeanus, synonym Saintpaulia goetzeana, is a species of Streptocarpus in the section Saintpaulia, commonly known as an African violet. It is a small, flowering plant that is used widely in home horticulture. S. goetzeana was first collected in 1898 by W. Goetze, and it was later described as a species by Engler in 1900.
How to grow it
Streptocarpus goetzeanus is very hard to cultivate due to the narrow conditions it needs to grow, such as mossy rock surfaces in deep shade. These conditions are hard to reproduce, making cultivation difficult.
Where it grows
Members of Streptocarpus section Saintpaulia are native to eastern tropical Africa. There is a concentration of species in the Nguru Mountains of Tanzania. This particular species is only found at the higher elevations of 1300–2000 meters.
