Comments:
A stately tree with a straight trunk and rounded crown that typically grows 30-50' tall. Small, greenish-white flowers appear in spring on long stalks female flowers in sparse clusters and male flowers in dense heads. Although flowers are not showy, they are an excellent nectar source for bees. Flowers give way to oval, 1/2" long fruits which are technically edible but quite sour. Fruits mature to a dark blue and are attractive to birds and wildlife. Spectacular scarlet fall color. Obovate to elliptic, entire to slightly toothed leaves to 5" long are dark green above and paler below.
Best grown in average, medium to wet soils in full sun to part shade. Prefers moist, acidic soils. Tolerates poorly-drained soils and can grow in standing water.
