Rhus trilobata Skunk bush Deciduous shrub (1 Page of 5) The Rhus trilobata plant species is found in Western N. America. It is a member of the Anacardiaceae family. Common gardeners may know the plant as Skunk bush. Some home gardeners know the variety as R. aromatica trilobata. R. trilobata. Nutt. or Torr.&Gray. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Rhus trilobata Common Name: Skunk bush Family: Anacardiaceae Author: Nutt. 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: 1.8 Mature Width: Habitat: Foothills, canyons, slopes etc, usually on dry rocky soils[62] and especially on limestone outcrops[149].
Cultivation Notes: Succeeds in a well-drained fertile soil in full sun[11, 200], but produces its best fruit when grown close to moist ground[85]. Judging by the plants native habitat it should succeed in dry soils[K].
The young growth in spring can be damaged by late frosts.
This species is closely allied to R. aromatica[11].
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.
