At full maturity this plant can stand to be about 40 inches tall. The Hophornbeam Copperleaf has rounded egg-shaped leaves that alternate one another along the stem with red coloration in the main veins and serrated margins. They are also monoecious plants, meaning that they have both male and female flowers on a single plant.
