Some botanists consider that the two should be regarded as a single species. This species has not been cultivated to a great extent but is a very attractive plant which deserves greater attention. Like many mint bushes it can be difficult to maintain in gardens for long periods. It prefers a well drained, moist position with some shelter from direct summer sun. Prostantheras respond to well to annual fertilising after flowering and are not as sensitive as some other Australian plants to phosphorus.
Propagation is easy from cuttings but seed can be slow to germinate.
In areas where the root-rot fungus Phytophthora cinnamomi is a problem, grafting onto the related Westringia fruticosa is recommended. You may have reached this description from one of several different sources.
