Betula nigra, commonly referred to as river birch, is native to Ontario and ranges throughout and ranges throughout North America. This species is a fast-growing birch known for its striking exfoliating bark. It can tolerate various soil conditions including sand, loam, and clay, but prefers moist well-drained soils, and is tolerant of occasional periods of drought once it has established. A popular and common cultivar in the nursery is Heritage� (�Cully�) and Dura Heat� (�BNMTF�), offering enhanced heat and drought tolerance, a pyramidal form, and vibrant pinkish-orange bark. Dura Heat is resistant to pests like the bronze birch borer and aphids, and performs well in warmer climates with superior bark color and foliage resilience. Both cultivars are well-suited for urban landscapes, though they can be moderately messy with fallen seeds and leaves. Planting single specimens in groups will result in longer life.
