Plectranthus is the largest South African genus in the mint family (Lamiaceae), with 44 species natural to South Africa, most of which occur on the eastern side of the country. Some species are narrowly endemic occurring only in a very limited area, while others are widespread and very variable and consequently difficult to distinguish. Among the South African members of the genus we have some of the showiest garden plants providing a mass display of colour in late summer and autumn. Colour selections range between pink, purple and white and many shades in-between. Plectranthus are noted for their aromatic leaves when crushed or even brushed against, and the variety of aromas is as diverse as the genus itself.

Plectranthus ecklonii or large spur-flower bush as it is commonly known has a wide distribution area, usually found on forest margins, and is best grown in semi-shaded areas of the garden. This Plectranthus species is a fast growing upright shrub that can grow up to 3 meters in height. The plant has square stems with purplish hairs in tufts at each node. The leaves are rather large and are arranged in opposite pairs on the stems. From March to May (Southern Hemisphere) be prepared for a stunning display of flowers!
