Rhus succedanea – Toxicodendron succedaneum – Wax Tree – Toxicodendron – Sumac –

Description

Rhus – Toxicodendron – Sumac – There are between 200-250 species of deciduous or evergreen shrubs, trees, and woody climbers, in the Anacardiaceae family, in this genus. They are found widely distributed in temperate and subtropical North America, Southern Africa, Eastern Asia and Northeastern Australia in woodlands, thickets, dry sites, bogs, and rocky slopes. Sumacs are grown for their alternate, simple, pinnate, or palmate leaves, which in many species and cultivars turn brilliant shades of yellow, red, or orange in autumn, some also produce showy fruit clusters. The inconspicuous 5 petaled flowers, usually 1/16″ across, are borne in spring or summer in dense terminal, normally erect, ovoid, or conical to pyramidal panicles in creamy white, greenish or red. In autumn the flowers are followed by spherical,, usually red fruits, up to 1/4″ across in dense clusters called sumac bobs. R. glabra, R. xx pulvinata, and T. typhina usually produce male and female flowers on separate plants, plants of both sexes must be grown together to obtain fruit. Grow in a shrub border or woodland garden, or as specimen plants. All parts of R. verniciflua are highly toxic if ingested, contact with the foliage, and that of a number of related species including R. succedanea, causes dermatitis and may aggravate skin allergies. Grow in moist but well drained, moderately fertile soil, in full sun to obtain best autumn color, with shelter from wind. Tolerant of air pollution. Prone to powdery mildew, Verticillium wilt, wood rot, leaf spot, blister, canker, dieback, scale insects, and caterpillars. R. succedanea – Toxicodendron succedaneum – Wax Tree – This spreading, deciduous tree, from Eastern Asia grows 30′ feet tall and wide. From softly hairy shoots it carries pinnate leaves, to 12″ long, which have 9-15 ovate-oblong, glossy, dark green leaflets, turning red in autumn.
