Black Gum

Swamp tupelo brings some of the most reliable red fall color of any native tree, setting the margins of pocosins and pinelands ablaze long before the maples get the credit.

Nyssa biflora grows naturally in flooded swamps, wet pinelands, and pocosins across the Southeast, where it can reach 60 to 100 feet in height and 20 to 40 feet in width. It is a slow grower but a long-lived one, tolerating wet sites that would drown most shade trees and resisting the effects of black walnut toxicity that limits companion planting options elsewhere in the garden. The flowers are inconspicuous green clusters in spring, drawing bees rather than admirers, but the autumn display of deep red foliage is among the more dramatic of any deciduous native.

Like its tupelo relatives it is dioecious, requiring both male and female trees for fruit production. It is difficult to transplant once established due to its taproot, so placement is a decision worth making carefully. In the right site, a naturalized area, a low lawn corner, or the edge of a pond, it needs little intervention and rewards patience with decades of reliable seasonal color and wildlife value.
