Overview
Betula nigra, the black birch, river birch or water birch, is a species of birch native to the Eastern United States from New Hampshire west to southern Minnesota, and south to northern Florida and west to Texas. It is one of the few heat-tolerant birches in a family of mostly cold-weather trees which do not thrive in USDA Zone 6 and up. B. nigra commonly occurs in floodplains and swamps.
Common questions
Is River Birch 'Dura Heat®' a good plant for Raleigh and the Triangle?
Yes—when the site matches its light and drainage needs. River Birch 'Dura Heat®' is used in Raleigh, Durham, and Cary landscapes in USDA zones 7b–8a. Confirm mature width, overhead wires, and how wet the Piedmont clay stays after storms before you plant.
When should I plant River Birch 'Dura Heat®' in North Carolina?
Fall (October–November) is the safest window for River Birch 'Dura Heat®' in the Piedmont: soil is still warm, air is cooler, and roots can grow before summer. Spring after the last frost works if you can water deeply through the first hot season.
Will River Birch 'Dura Heat®' grow in Piedmont clay?
It can, with careful planting: wide hole, crown slightly above grade, and no water sitting on the root flare. Heavy, poorly drained clay is the usual failure mode—not summer heat alone.
