About plant names...

The American white birch or paper birch is a native of North America. Papyrifera means "paper"—the white, peelable bark is smooth and paperlike.

Identification: The paper birch reaches about 60′ (18 m) in height, rarely up to twice that. The trunk (sometimes multiply stemmed) is typically bright white, up to 1′ (30 cm) in diameter, with a peeling, papery bark. However, young trees consist of a reddish bronze bark that does not peel, and sometimes, especially in western trees, this bark remains throughout the tree's life. Trees tend to be pyramidal when young, becoming more irregular as they age. Leaves are alternate, ovate, with pointed tips; dark green above, pale green below, yellow in the fall. Both male and female flowers occur on the same tree. Male flowers are catkins 2-4″ (5-10 cm) long. Female flowers are also catkins, 1-1½″ (2.5-3.8 cm) long.

Please don't peel bark from these trees—it can kill them!
