Plectranthus ernstii is a slow growing, semi-succulent perennial with swollen stems and a compact habit that resembles a bonsai. It is an ideal plant for containers and rock gardens. It has bright green to yellowish green aromatic dentate leaves. Over time it forms thick caudiciform stems and root.
During its winter dormancy, this plant will tolerate drought, but should probably be watered more frequently than most other succulent plants (perhaps once every three weeks is best).
This plant makes an interesting bonsai subject. Over time it forms thick caudiciform stems and root. Prune plants as desired apply a well-balanced fertilizer every few months in summer. This plant needs well-drained soils to avoid rot.
Pruning is a renewal process and occurs in the natural habitat. Dead, diseased and weak growth is removed and the natural form is improved. The optimum pruning time is late winter, once the plants have finished flowering.
