Sorbus Americana American Mountain Ash

Sorbus Americana American Mountain Ash is an ornamental tree. American Mountain Ash requires full sun and moist, acidic, humusy, well-drained soil. The tree consists of each odd pinnate leaf typically having 9-17 sharply serrated, lance-shaped, dark green leaflets with gray-green undersides that turn yellow in fall. In May, American Mountain Ash produces dense flattened clusters of very small 5-petaled white flowers. American Mountain Ash is suitable for use as a specimen. It also bears bright orange-red berries that ripen in late summer and remain on the tree after leaf drop.
