Pin Oak is partial to moist soil. It is a hardy tree, widely used in street and ornamental planting. Pin Oak is widely cultivated in Europe. Acorns are small (about 1/2 in. long), rounded, with a shallow cup.
Northern Pin Oak takes its name from the many short pinlike twigs that clutter the horizontal or downward-sloping branches. These make identification easy in winter. The leaf has five to seven deep lobes with long teeth; it is dark green above, lighter and smooth below. The gray-brown bark remains smooth for some time, gradually breaking into scaly ridges.
