Cultivation

They need very well-drained, preferably sandy soil and prefer a sunny spot, although they will tolerate some shade. They prefer drier, temperate zones and need only be watered sparingly. Prune regularly to keep them tidy and to prolong flowering. Propagate from fresh seed or cuttings. They are prone to fungal diseases in humid conditions. Some success has been had by grafting them onto Westringia stock.
