The Sambucus nigra ssp cerulea is leggy deciduous shrub grows up to 20 feet tall, and has soft, pithy stems. Leaves are composed of long, narrow leaflets divided into five to nine leaves. The creamy-white flowers are arranged in dense, flat-topped clusters and mature into waxy, blue to dark-blue (sometimes black) berries.

Twigs and leaves are preferred by deer and elk and flowers attract hummingbirds and butterflies. Berries are eaten by numerous small mammals and birds.
