Sorbus americana Red Cascade

Red Cascade Mountain Ash

Red Cascade mountain ash (Sorbus americana 'Dwarfcrown') forms a compact oval tree with glossy leaves. White spring flowers, orange-red fruits, and yellow-orange autumn foliage give it a varied seasonal display.

The canopy loses its leaves for winter. Autumn color includes orange and yellow. Allow the natural framework to develop without crowding neighboring plants or paths.

Choose a sunny position with well-drained soil. Water during establishment and allow enough room for the developing crown. It performs best in cooler climates.
