Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Rhus sempervirens Family: Anacardiaceae Author: Scheele. Known Hazards: There are some suggestions that the sap of this species can cause a skin rash in susceptible people, but this has not been substantiated. See also notes in 'Cultivation Details'. Mature Height: 3.5 Mature Width: Habitat: Dry slopes[181], rocky hillsides and cliffs, 600 - 2250 metres[149].
Cultivation Notes: We have very little information on the hardyness of this species and do not know if it will succeed outdoors in Britain. It is unlikely to succeed anywhere outside the mildest areas of the country. The following notes are based on the general needs of the genus.
Succeeds in a well-drained fertile soil in full sun[11, 200].
The young growth in spring can be damaged by late frosts.
Plants have brittle branches and these can be broken off in strong winds[200]. Plants are also susceptible to coral spot fungus[11]. Plants in this genus are notably resistant to honey fungus[200].
Many of the species in this genus are highly toxic and can also cause severe irritation to the skin of some people, whilst other species such as this one are not poisonous. It is relatively simple to distinguish which is which, the poisonous species have axillary panicles and smooth fruits whilst non-poisonous species have compound terminal panicles and fruits covered with acid crimson hairs[1, 4]. The toxic species are sometimes separated into their own genus, Toxicodendron, by some botanists[200].
Dioecious. Male and female plants must be grown if seed is required.
