Genus

Betula

The Betula genus in the Plotwright catalog — 4 species: Paper birch, River birch, Silver birch, Sweet birch. Open any for hardiness, native range, wildlife value, and growing guidance.
Betula papyrifera
Paper birch
A northern native deciduous tree producing iconic white peeling-paper bark — among the most recognizable + photogenic of any temperate tree. Native to northern + boreal forests; declines in southern landscapes due to heat stress + bronze birch borer pressure. Short-lived (40-70 years) compared to most native canopy trees but provides outsized visual + wildlife value during that window.

Betula nigra
River birch
The most heat-tolerant native birch — exfoliating salmon-pink-to-cinnamon bark provides four-season visual interest, and the species thrives in warm humid southern landscapes where paper birch fails. Native to riparian + floodplain habitats; tolerates wet feet + occasional flooding. Resistant to bronze birch borer (the canonical birch killer). The Heritage cultivar is the residential standard.

Betula pendula
Silver birch
A graceful, fast-growing pioneer tree prized for its brilliant white peeling bark, fluttering diamond-shaped leaves that turn clear yellow in fall, and slender weeping branchlets. POWO (Kew) records it as native across Europe and northern Asia, from the Atlantic seaboard to Siberia, making it one of the most cold-hardy of all broadleaf trees. It thrives where little else will — poor, dry, acid soils — and casts only light, dappled shade, so a rich underplanting can grow beneath it. Be honest about the trade-offs: it is relatively short-lived (typically 50-80 years), shallow-rooted, a thirsty competitor near borders, and its abundant wind-borne spring pollen is a significant hay-fever allergen.

Betula lenta
Sweet birch
A handsome cool-climate native birch set apart from the white-barked birches by dark, smooth, cherry-like bark that does NOT peel and intensely golden-yellow fall color. Broken twigs and inner bark smell strongly of wintergreen — historically the source of oil of wintergreen — and the sap is tapped for birch beer and syrup. Markedly more resistant to the bronze birch borer than white-barked birches, but a cool, moist, acidic-soil species that struggles with heat, drought, and compacted urban soil. Also called black birch or cherry birch.
