Betula populifolia Marshall Gray birch, yellow birch
Gray birch is a North American native. Plants: Trees reach 33′ (10 m) in height, often with multiple trunks, and are pyramid-shaped in form. Bark is dark reddish brown on young trees, becoming white as the tree ages. While white birch bark is a brighter color, and tends to peel easily, gray birch bark is tighter, less likely to peel; and darker, more often interrupted by black markings that are often chevron-shaped. Leaves: Leaves are fairly triangular in shape (ovate to deltate or rhombic, if you want to get technical). They have irregular and sometimes doubled serrations. Flowers: Both male and female flowers are found on the same tree ("monoecious"). Male flowers are yellow-brown, 1-3″ (2.5-7.6 cm) long, less than ¼″ (6.3 mm) in diameter, usually drooping; female flowers are green, about 1″ (2.5 cm) long, ⅛″ (4.8 mm) in diameter. Edibility: The inner bark can be cooked or dried, then ground into a meal which may be added to flour, though this is typically done only when more convenient forms of starch are not available. Sap is also edible. Though not nearly as sweet and tasty as that of some maple trees, it is a source of carbohydrates in a pinch. Online References:
