Light
Blackgum is not likely to be deliberately regenerated, although its utility for wildlife purposes may lead to its encouragement. Clearcut, shelterwood, and group selection methods all work well.

Water
Blackgum is found on many different sites, including moist bottomlands and very dry uplands.

Growth

Size
A medium sized tree reaching up to 80 feet tall on moist sites, generally much shorter in the mountains. On younger trees the branches often stand at right angles to the trunk with numerous short, curled spur shoots present.

Timber Value
Blackgum's light, uniformly textured wood makes good containers, crossties, pallets, lumber, flooring, paper pulp, rollers in glass factories, gunstocks, and occasionally veneer.

Wildlife Value
Blackgum fruits are a good source of crude fat, fiber, phosphorous, calcium, and are consumed by many species. Young sprouts are browsed by deer. Cavities are common in blackgums, making the tree useful for dens and nesting. Flowers provide nectar for bees and other insects.

Fun Facts
Blackgum can tolerate a very wide variety of sites, from flooded swamps to dry shales. It grows slowly and can live for a long time - the oldest known specimen is nearly 700 years old. Blackgum's shiny leaves are amongst the first to break bud in the spring, and some of the first to turn brilliant red in the fall. The intense fall foliage lends ornamental value.

Latin Meaning
Nyssa: Greek "Nysa" - a water nymph / sylvatica: of the woods - Latin "silva" (forest)
