Betula nigra 'Cully'(HERITAGE)

Betula nigra ‘Cully’ (HERITAGE®) — commonly called Heritage River Birch — is a superior selection of native river birch prized for its lighter, cream-to-salmon exfoliating bark, improved uniformity, and excellent heat tolerance. Compared with the straight species, ‘Cully’ shows cleaner bark color and a more refined habit, making it one of the most widely planted river birches in landscapes.
