Comment:

Quercus shumardii, commonly called Shumard oak, is a medium-sized, deciduous tree of the red oak group. Pyramidal in youth but spreads to a broad open crown with age. Typically grows at a moderately fast rate to a height of 40-60' (to 100' in the wild).  Its bark develops dark, deep furrows, with light gray to white, scaly ridge tops.

Shumard oak is a deciduous tree in the Fagaceae family.  The leaves turn russet-red in fall.  It looks a lot like northern red oak (Quercus rubra) but its leaves have fewer and deeper lobes. This species also seems to be more tolerant of heavy clay soils than northern red oak.  This tree is moderately salt tolerant.
