State Tree of New Jersey
Northern Red Oak
Appears with the leaves in April or May.
Acorns are 3/4 to 1 inch long and nearly round. The cap is flat and
thick, covering about 1/4 of the acorn. Mature in 2 years, ripens August to late October.
Quite stout, red-brown, and glabrous. Terminal buds are multiple, quite
large, ovoid, and covered with red-brown, mostly hairless scales.
On young stems, smooth. Older bark develops wide, flat-topped ridges
and shallow furrows. The shallow furrows form a pattern resembling ski tracts.
A medium-sized to large tree that develops a short trunk and round crown when open grown, straight with a clear bole when grown with the competition.
