Common gardeners may know the plant as Elm-leaved sumach. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Rhus coriaria Common Name: Elm-leaved sumach Family: Anacardiaceae Author: L.

This species is not very hardy in Britain and is unlikely to succeed outdoors in any but the mildest parts of the country[11, 200]. Another report says that the plant is quite hardy and is often grown in British gardens[4]. The young growth in spring can be damaged by late frosts.
Unlike most members of this genus, this species is hermaphrodite[200].
The form 'Humilior' from Italy is smaller growing[182].
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, including this one, are highly toxic and can also cause severe irritation to the skin of some people, whilst other species 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].
