Aralia elata seedling on weedy bank A. A. Reznicek seedling on weedy bank

A native of Asia, apparently rarely spread from cultivation into disturbed areas and forest edges, probably mostly by root suckers. First collected in 1923, in Washtenaw Co.

This is a tall erect prickly shrub or small tree. Specimens are mostly not explicit as to whether the plant was truly established outside of cultivation. In addition, herbarium specimens of these large-leaved plants are generally very incomplete, and most specimens were originally named A. spinosa L., Hercules-club, a less commonly cultivated species native farther east and south in the United States, with umbels in an elongated panicle (as long as a meter). See Moore, Glenn, & Ma (2009) for more details.

Other species of woody Aralia besides these two are occasionally cultivated, however, and some of the incomplete specimens could conceivably represent these.
