Spur flower Plectranthus

Other Common Name(s):

Description

Plectranthus is a genus of about 85 species of annuals, evergreen perennials, semi-succulents, and shrubs native to Africa and India in the Lamiaceae (mint) family. These plants vary greatly depending on the species. Some are grown as ornamentals, ground covers or for their attractive foliage.

These plants are often used in hanging baskets, containers, in the front of the border, or to add color during the growing season. They generally need well-drained amended soils in part sun to shade.

Insects, Diseases, and Other Plant Problems: Mealybugs, spider mites, leaf spots, and root rot can sometimes be problems.
