Sorbus scopulina
Common Name Western Mountain Ash
Family Rosaceae (Rose Family)

 

Description

This shrub can be anywhere from 1-4 meters tall. It bears whitish or yellowish bark. Leaves are pinnately compound, characteristic of most ashes. The leaves have sharply serrated margins. The berry is scarlet to orange, drying to a dark purple.

Range

Found at 6,500' to 9,000' from the east slope of the Rocky Mountains west across the mountainous regions of the Great Basin.

Culture

Needs moderately moist soils; not particularly drought tolerant.

Value

Needs placement in either more moist soil or to receive more frequent irrigation, but where used it is an attractive large shrub that has the typical Sorbus berries and bright red fall color. Uncommon in the trade.

Propagation

Seeds must be recovered from the fruits before the birds have a chance to eat it. The seeds are easily germinated after at least 60 days of prechilling. To start indoors cold treat for 60 to 150 days. Sow in container and cover to depth. Seed will germinate sporadically from 30 days to 6 months. Because of such a long germination time it is often desirable to start seed in the desired location in the fall. Cover with 1/8" soil and water in. Be sure to water them in the winter if it is dry for more than 1 ½ weeks as these plants most often occur in moist locations.
