The tree heath, a member of the evergreen ericaceae family, is native to southern Europe and east Africa where it can grow to fairly tall tree. The fragrant grey-white, borne in dense terminal clusters, appear in spring. Because of its small, needle-like leaves, the plant does not transpire much, which means that it does not mind prolonged periods of drought. They prefer a sunny position but need plenty of lime-free water during the growing and flowering season; however they must not be . Although tree heath is more tolerant of lime than other species, it should be planted in peaty . It will tolerate slight frost but it is best to over-winter it in a light, well-ventilated room at a temperature of 5-10° C (41-50° F). It needs regular watering even during the winter. It can be propagated from semi-ripe cuttings taken from non-flowering shoots in mid-spring. Older specimens can be cut back if necessary.
