Sorbus decora, commonly known as the northern mountain ash,[1] showy mountain-ash,[2] or dogberry, is a deciduous shrub or very small tree native to northeastern North America. It occurs throughout the Laurentian Mixed Forest Province, the New England-Acadian forest region, and the eastern Canadian boreal forests.

Description

Showy mountain-ash grows 4–10 metres (13–33 ft) tall. Its leaves are odd-pinnately compound, with 11–17 leaflets. Each leaflet is 5–10 cm (2–4 in) long and 1–2.5 cm (38–1 in) wide. All parts are hairless to slightly hairy. Flowers are borne in 125- to more than 400-flowered panicles 6–25 cm (2 149 34 in) across. Each flower is 5–7.5 cm (2–3 in) across and has five white petals 2.5–3.5 mm (33218 in) long, 14–20 stamens, and carpels with 3–4 styles. The fruits (pomes) are bright red to orange-red and 4–7 mm (532932 in) across.[3]

Similar species

Showy mountain-ash is very similar to the closely related American mountain-ash (Sorbus americana). Like the American mountain-ash, the showy mountain-ash has odd-pinnately compound leaves and often large clusters of flowers and fruits. Showy mountain-ash can be distinguished by its shiny, sticky buds,[4] and its slightly larger flowers and fruit.[2] It is said to bloom a week earlier.[3]

Uses

It is often cultivated as an ornamental plant for its cold-hardiness, its attractive flowers, and its large clusters of small red berry-like pomes.

The fruits are an important source of food for wildlife, particularly birds in the winter and early spring.
