Black Gum

Black Gum

Closeup of Foliage Black Gum

One of the best, most consistent, and beautiful trees in the fall. Native to eastern North America and is the source of Tupelo honey. The Black Gum can be difficult to identify as a small shoot due to its variable nature. These trees can live to be over 400 years old. Difficult to transplant seedlings because of the taproot, but if container grown and moved in small sizes it will re-establish quite well.

Bark: Dark gray, brown, brown-black, and at times almost black; broken into thick ridge-like segments giving it a block-like appearance.

Foliage: Alternate, simple, obovate or ellipitcal. Three to 6 inches long and 1 1/2 - 3 inches wide. Dark green in the summer changing to fluorescent yellow to orange to scarlet to purple colors in the fall.

Flowers: Polygamodioecious, appearing with the leaves, small greenish yellow.

Fruit: Oblong drupe, 3/8 - 1/2 inch long, bluish black ripening in late September through early October and persisting until November. Fruit is eaten by many species of birds and mammals.
