Boxelder Tree
(Acer negundo)
Boxelder is native to portions of the southern tier and Susquehana Valley, but has become more broadly established throughout many parts of the state. Boxelder grows commonly along the banks of streams and rivers, and may occur as a weedy species in urban areas where its seeds are able to germinate. Boxelder has a soft wood that has no commercial value, but is important for wildlife and the stabilization of stream banks where it grows. Boxelder is not recommended for horticultural plantings.
