All there is to know about cape mallow

Anisodontea flower

Anisodontea, also called Cape mallow, is a beautiful shrub that blooms generously over an extended portion of the year.

Native to South Africa, it grows particularly well in southern temperate climates or along the Atlantic coast.

Even though its foliage is evergreen, a cold spell that lasts more than a couple days will make it lose its leaves.
That’s why it is recommended to leave this plant outdoors only if winters are very mild.

Among the most common and favored varieties, Anisodontea capensis, also called dwarf pink hibiscus, is famed for its pink flowers with a red center. There are also Anisodontea hypomadarum which has magnificent pink blooms, and Anisodontea malvastroides which boasts pastel pink flowers.

The name “Anisodontea” comes from the greek word aniso which means “uneven” and odon which means “without teeth”.
