Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Rhus glabra Common Name: Smooth sumach Family: Anacardiaceae Author: L. 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: 3 Habitat: Thickets and waste ground on dry soil and by streams[4, 43, 60]. The best specimens are found in rich moist soil[149, 229].
General Uses: The leaves are rich in tannin, containing about 10 - 25%[171]. Up to 31.2% has been obtained from some plants[223]. They can be collected as they fall in the autumn and used as a brown dye or as a mordant[169]. The twigs and root are also rich in tannin[149].
A black and a red dye is obtained from the fruit[4, 257].
A black dye is obtained from the leaves, bark and roots[257].
An orange or yellow dye is obtained from the roots harvested in spring[46, 61, 257].
A light yellow dye is obtained from the pulp of the stems[257].
The inner bark, mixed with bloodroot (Sanguinaria canadensis) and the inner bark of wild plum (Prunus sp) has been used to make a yellow dye[257].
An oil is extracted from the seeds[4]. It attains a tallow-like consistency on standing and is used to make candles. These burn brilliantly, though they emit a pungent smoke[4].
The plant has an extensive root system and is fairly wind tolerant, though branches can be broken off in very strong winds. It is planted for soil stabilization and as a shelter screen[200]. It can quickly establish itself in open sunny locations and so can be used as a pioneer species for establishing woodlands[229].
Wood - soft, light, brittle[101, 149].
