This plant is weedy. We do not recommend planting it in Hawai’i.
Gunpowder tree or charcoal tree, which was used for making charcoal for gunpowder, is native throughout the old world tropics and weedy on most major Hawaiian Islands. It is rarely cultivated, and further planting should be avoided. The trees are fast-growing, with spreading branches that droop at the tips, reminiscent of elms, which are related. Trema orientalis has a HPWRA (Hawai'i Pacific Weed Risk Assessment) score of 10 (High Risk).
Native to Southern China, Kyushu, and the Ryukyu Islands.
