Facts

Paper birch is easy to spot in forests of the northeast, with its tall trunk marked by unique, white bark that peels off in large, papery rolls that are pink inside. Young saplings are quite elastic and sometimes bend to the ground under the weight of ice. The famous poet, Robert Frost, reminisces about swinging on these boughs as a boy in his poem, "Birches" (from the collection, "Mountain Interval," published 1916). Paper birch is the source of skin for the traditional birch bark canoe. Pliable birch wood is also used to shape the frames of snowshoes and for veneer, pulpwood, and plywood. Beaver eat the pink inner bark, while snowshoe hare nibble the young seedlings. This short-lived but fast-growing tree is also planted for its ornamental value because its white bark provides a dramatic contrast in the garden.

7.  Betula papyrifera Marsh. N

paper birch. Betula alba L. var. commutata Regel; B. papyrifera Marsh. var. commutata (Regel) Fern.; B. papyrifera Marsh. var. macrostachya Fern. • CT, MA, ME, NH, RI, VT. Deciduous and mixed evergreen-deciduous forests, ascending to moderate elevation (but usually replaced by Betula cordifolia at higher elevations).

7×11. Betula papyrifera × Betula pumila → Betula ×‌sandbergii Britt. is a rare hybrid that occurs in VT. It is a shrub or small tree with dark red-brown, close bark. The oval to ovate leaf blades are 2.5–6.5 cm long with serrate margins, acute at the apex and cuneate at the base. The body of the samara is wider than its individual wings.

Native to North America?

Yes

Sometimes confused with

Betula cordifolia:
leaf blades slightly heart-shaped at the base, bark pink-white to brown-white or red-brown-white, and scales of fruiting catkins with ascending lateral lobes (vs. B. papyrifera, with leaf blades wedge-shaped to truncate at the base, bark bright white, and scales of fruting catkins with divergent lateral lobes).
