Plant Species of the genus Aralia

Information about this genus
Name: Aralia
Cultivation: CULTIVATION: All the species known in cultivation will tolerate at least light frosts, but most need a warm, humid summer for best growth. They like a deep, reasonably fertile soil and shelter from strong winds. Although shade tolerant, they grow and flower better in the sun. Propagate from seed, which for the tree species may need cold stratification, or from root cuttings or basal suckers.
Description: An interesting genus of trees, shrubs and herbaceous perennials, Aralia consists of around 40 species mostly from Southeast Asia and North America, with a small number from Central and South America. Most are deciduous and nearly all have large compound leaves. The flowers are small but numerous, usually cream, carried in small umbels that in turn are arranged in large panicles terminating the branches. They are followed by black fruits almost identical to those of Hedera (ivy) and Fatsia, to which Aralia is closely related. Some of the tree and shrub species have prickly stems and are inclined to sucker from the roots. Several of the tree aralias are grown as ornamentals in temperate gardens, valued for their foliage texture as well as their display of summer blossom. The roots and bark of several species have been used in traditional medicine, while the young shoots of the herbaceous A. cordata are an important vegetable (udo) in Japan, used like celery. Aralia once included plants now placed under Fatsia, Polyscias, Schefflera, Tetrapanax and several other genera.
