Castor aralia
Kalopanax septemlobus
It is mainly native to northeast Asia, where it grows up to 30 metres tall; in Poland it is not likely to exceed 10 metres. A solitary specimen grows in the new park section on the slope, next to a plane tree. Aralia leaves resemble those of a maple or a star gum, but look more like fingers separated by deep lobes.
The sizeable umbels of white flowers attract many pollinators in late summer. The tree’s Polish name refers to its numerous spines, which grow mostly on young shoots. In Korea its cooked leaves are considered a delicacy.
