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.
Bark
- smooth on younger trees but soon developing narrow ridges and shallow
furrows. Ridges and furrows are interlacing. Bark on mature trees
is dark brown.

Twigs
- moderate to very stout, smooth and covered
with a waxy film giving the twig a shiny green to purple color.
Winter
buds - white and covered with a hairy scale. Buds held tightly against the twig. Buds are located on
the twig within leaf scars having a "v-shaped" notch.

Leaves
- pinnately compound and opposite,
usually 5 leaflets; often resembles poison ivy, which has alternate,
pinnately (3 leaflets) compound leaves.

Fruit
- large clusters of V-shaped samaras; mature in autumn

Outstanding
features - pinnately compound leaves,
purple to green twigs, ridged and furrowed bark
