Overview

The Snakebark Maple, also known as **Moosewood, Striped Maple, Whistlewood, or Goosefoot Maple** (Acer pensylvanicum), is a **distinctive, small understory tree** native to the cool, moist forests of eastern North America (Canada to Georgia, west to Minnesota). It is celebrated for its **striking green-and-white striped bark**—a feature that provides year-round interest, especially in winter.

Signature Bark & Foliage

The **young bark is smooth, olive-green to gray-green, with prominent vertical white stripes** (snake-like). As the trunk ages, the stripes may fade to a mottled gray-brown. Leaves are **large (5–7 inches), 3-lobed (goosefoot-shaped), thin, bright green**, turning a clear, bright yellow in fall. The foliage is unusually large for a maple, giving a tropical texture.

Flowers, Fruit & Form

Yellow-green, pendulous racemes of flowers appear in spring (after leaves). Samaras (keys) are borne in long, drooping chains, maturing in fall. The tree grows **15–25 feet tall and wide** with a short trunk and spreading, open, rounded crown—perfect for the woodland understory.

Culture & Site Specificity

**USDA Zones 3–7.** **Requires cool, moist, well-drained, acidic soil and shade (especially afternoon shade).** **Intolerant of heat, drought, compacted soil, and pollution.** A tree for the **woodland garden, shaded ravine, or north-facing slope** in northern climates. Struggles in the South (Zone 7+). The striped bark is a winter jewel—plant where it can be appreciated against snow or dark evergreens. A native gem for the right cool, shady niche.
