Plectranthus species are universally recognised in frost-free sub-temperate and subtropical climates as excellent shade plants. They are also often used as house plants, and will usually thrive in deep shade where many plants struggle for lack of sunlight. In the shade the leaves are typically fresh green, broadly ovate and either pointed or rounded at the tip. In the sun the leaves stay small, become maroon and slightly more succulent. The small white flowers are 10–12 mm long with a distinct swollen section at the base, narrowing to a throat and then flaring slightly at the mouth. It grows on well-drained humus rich soils on rocky ridges in heavily shaded kloofs and forests.
