Once the plants have been established for a year or more they become woodier at the base and are more resistant to frost damage. The ground cover species often have very attractive foliage and form dense attractive carpets from 150mm to 450mm thick, which burst into flower in autumn. They root readily at the nodes wherever they touch the ground, and will form dense mats in a relatively short time. Once again most species enjoy shade but there are a few which can endure full sun. Plectranthus are exceptionally easy to propagate and can be produced very easily with little special treatment.
Most propagation is done from cuttings during the early part of summer and spring.
Although the cuttings will root at any time of the year, they have a long summer ahead to establish if they are propagated at this time. The cuttings should have at least two nodes and the leaves should be removed from the lower portion. Rooting hormone is usually not necessary and has been known to cause the cuttings to rot. The cuttings should be inserted one third of their length into clean double washed river sand and kept in a warm shady place and not be allowed to dry out.
