This species is native to western North America from Alaska & the Yukon & western Northwest Territories down into the mountains of central California & Arizona & New Mexico on rocky hillsides, open woods, meadows, along streams, or infrequently in wetlands. It is usually a large shrub, but can be a low shrub or a small tree. Its pinnately compound leaves have 9 to 13 leaflets with leaflets 1 to 3 inches long. The foliage is shiny, light green, with deep veins, and sharp marginal teeth. The new growth and winter buds are white and sticky. The dense white flower clusters are slightly fragrant. The tart orange to scarlet fruit is edible raw if it has gone through a few frosts and can be used for jams and jellies and wine. It is offered by some native plant nurseries out West. It is a handsome woody plant like other Mountain-Ashes, but it is not common in cultivation.
