Description

Blackgum is a deciduous tree that may grow 50 to 80 feet tall. The tree has alternative leaves with a smooth margin. On sprouts or young trees, leaves may have a few coarse teeth. The bark is light gray and deeply furrowed to create rectangular or square ridges (cobbled). In spring, small, light green flowers mature in clusters. The tree produces an egg-shaped, blue-black fruit which matures in the fall.

The bark is light grey and deeply furrowed to create rectangular or square ridges (cobbled).

Tupelo honey is highly prized. Black tupelo has a flowering habit that is polygamodioecious. Polybamodioecious is a big word meaning some plants have mostly male flowers while others have mostly female flowers, with most plants having a few perfect flowers. This would account for some plant being loaded with berries, while others may only have a few berries.

This tree is moderately salt tolerant.
