A small shrub, the Sitka Mountain Ash is found across western North America and is more often seen on the coast than S. scopulina.

Growing only to 3-10, it forms multiple stems.

The fine foliage is composed of 7-11 leaflets along a leaf axis and they put on a spectacular display of orange and red in autumn.

In spring, clusters of creamy white flowers form, followed by glossy red berry-like fruit, very attractive to birds.

Found from Alaska to northern California and east into the Yukon and Montana (USDA 3-10), s. sitchensis prefers moist, rich soil and several hours of full sun.
