How to Identify

A herb up to 50 cm high and covered with hairs. It spreads to 30 cm across. The stems and branches are square. They are usually purple. The leaves are opposite. The leaf stalks are 1-4 cm long. The leaves are 3-7 cm long by 1.5-5 cm wide. They are oval or sword shaped. The edges of the leaves are toothed. The leaves have a smell when crushed. The leaves can be dark red, purple, or green and hairy. The flower clusters are erect and at the end of the shoots. The flowers are 5 mm long. They are purple or bluish. The nutlets are brown and broadly oval. They are 1-1.2 mm long. They are shiny.

How to Grow

It grows readily from cuttings. It also grows wild from seed. Seeds germinate easily.

Propagation: Seed - sow in well-drained soil, covering lightly with a thin layer of sand, and place in a warm but shaded spot. The seed germinates in about three weeks. Cuttings of Plectranthus species generally root easily - soft tips root faster than semi-hardwood growth. The cuttings are best taken 60 - 100mm long with three or four nodes, making the cut just below a node. Place them in sand, perlite, vermiculite or peat, or any mixture of these, keep them moist and shaded and they should root in 2 - 3 weeks

Medicinal Uses

Traditional uses documented in ethnobotanical sources, though specific medicinal applications are not detailed in available data.

Other Uses

The sap from the leaves of the wild, purple-black species is used in tattooing. The plant is used as a living fence in coffee plantations.

Other Information
