About plant names...

The American mountain-ash is a native of eastern North America. American mountain-ash is so named because it is often found in mountain locations—all these photos are from the mountains. They are also quite popular as landscape trees.

Plants: Trees reach 10-30' (3-9.1 m) in height and trunks are about 4-10" (10-25 cm) in diameter. Bark is light gray and smooth.

Leaves: Leaves occur in groups 13-17" (33-43 cm) long. Individual leaflets in each group are about 2-3" (5-7.6 cm) long and ⅝-1" (1.6-2.5 cm) wide.

Flowers: Tiny white flowers, each ⅛" (3.2 mm) around, occur in large groups.

Fruits: Flowers become thick clusters of bright orange-red berries, ⅛-¼" (3.2-6.3 mm) around.

Edibility: Raw mountain ash berries aren’t good for you, but they can be cooked into a beautiful jelly that is traditionally served with lamb, venison, or pork. The recipe is described in Backyard Foraging.
