Latin Name:  Rhus x pulvinata
Family:  Anacardiaceae
Author:  Greene.

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   Mature Width:  5

Habitat:  Usually found in upland sites on rich soils, but it is also found in gravel and sandy nutrient-poor soils.

Cultivation Notes: Easily grown in a wide range of soils, from dry to moist, acidic or alkaline, including shallow chalk soils[214]. Succeeds in a well-drained fertile soil in full sun[11, 200]. Tolerates poor sandy soils[200]. A very hardy plant, when fully dormant it can tolerate temperatures down to at least -25°c[200]. However, the young growth in spring can be damaged by late frosts. A naturally occuring hybrid, R. glabra x R. typhina[11, 214]. A very ornamental and variable plant, there are some named varieties[214]. The cultivar 'Red Autumn Lace' (often erroneously labelled as R. glabra 'Laciniata') is a female form that fruits freely[214]. A good bee plant[K]. Single-stem plants are short-lived in cultivation, but if the plants are coppiced regularly and allowed to form thickets, then they will live longer and also be more ornamental with larger leaves[238]. Any coppicing is best carried out in early spring[238]. 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.
