About

Aralia spinosa L. is a substantial, deciduous shrub or small tree that can reach heights of up to 6 meters. This plant is characterized by its robust stems and leaf stalks, which are armed with sharp spines. Its large compound leaves, measuring as much as 1.5 meters in length, feature toothed leaflets and are arranged on sparse, club-shaped branches that create a canopy resembling an umbrella. In the summer, it produces greenish-white flowers with five petals, which are clustered in large panicles, subsequently giving way to fleshy, round fruits that are purple-black in color.

About the genus

Aralia includes deciduous trees, shrubs, and perennial plants characterized by their sizable, either simple or pinnately compound foliage. The species produce small greenish-white flowers that cluster in large groups at the ends of branches, which eventually give way to small black fruits.
