Carya ovata (Mill.) K. Koch

Shagbark hickory

Shagbark hickory is common in eastern North America.

Plants: Trees are 70–100′ (21–30 m) tall, rarely up to 150′ (45 m). The bark is smooth and gray when young, becoming “shaggy” with age, with long loose scales.

Leaves: 8–14″ (20–35 cm) long, pinnate, in groups of 5 or 7. They are pale green and fuzzy on the bottom; oval-shaped, pointed on both ends, with small sharp serrations.

Flowers: Staminate (male) flowers are borne on long-stalked catkins at the tip of old wood or in the axils of the previous season’s leaves. Pistillate (female) flowers occur in short terminal spikes.

Fruits: Shagbark hickory nuts are green. This is really a husk, consisting of four sections that open as they dry, releasing the nuts inside. Nuts are ⅞–1½″ (2.5–4 cm) long, with very hard shells.

Habitats: Habitats are highly variable, depending upon climate.

Edibility: Nuts are edible, and have a sweet, nutty taste.
