Plectranthus fruticosus is an erect shrub up to 2m high. Branches have purple hair at the nodes. Leaves are broadly ovate, almost succulent and also purple below. The spikes of pink to mauve flowers are tinged with purple beneath.
Plectranthus fruticosus should be pruned after flowering and planted in shade or semi-shade. It attracts insects and butterflies and therefore also attracts birds. Effective as a fly repellent – rub your windowsills with the stems.
