Birch – Heritage Clump
Heritage® River Birch | Betula nigra 'Cully'
This vigorous grower is noted for its exfoliating bark, paler than river birch and ranging from warm tan to creamy and parchment white. Adaptable to both wet, poorly drained soils and upland conditions, it is also resistant to bronze birch borer. Plants naturally develop into clumps of three or more stems. In 2002, it was honored as Urban Tree of the Year by the Society of Municipal Arborists.
