This species was once common in western Sydney but much of its habitat has been lost to the suburban sprawl. It is not well known in cultivation and seems difficult to maintain for long periods even in areas where it grows naturally. Like most prostantheras it prefers a well drained position with some shelter from direct summer sun. It is a beautiful, small shrub - well worth persisting with. 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.
