- Ecological Threat
- This tree is demonstrating invasive characteristics in suburban and urban fringe forests. It escapes intended plantings to invade and displace native hardwood forest. Note: only female plants have potential to become invasive. Phellodendron amurense is native to eastern Asia and was introduced into the United States in 1856. Trees prefer full sun and rich soils.
