Discover Kalopanax septemlobus, often known as Castor Aralia or Prickly Castor-oil Tree, the only species in the Kalopanax genus. This deciduous tree is part of the Araliaceae family and thrives in the northeastern regions of Asia, from Sakhalin and Japan west to southwestern China. It is recognizable by its maple-like leaves, dark gray ridged bark, and white flowers which bloom in late summer, sometimes forming large 2-foot clusters. This tree's younger stems bear spines, adding an intriguing appeal. It prefers deep, rich soil and full sun. As a mature tree, it becomes a remarkable shade provider and is sometimes grown out of pure curiosity due to its dominant, coarse stature with a loosely rounded crown. Its leaf lobes are remarkably variable, echoing the unpredictability of Mother Nature herself. You might find it cultivated as an ornamental tree in Europe and North America, contributing a 'tropical' touch to the landscape with its large palmate leaves. Despite this exotic appearance, the Kalopanax septemlobus is impressively hardy, standing tall and unfazed in temperatures plummeting to -40°F.
