Blue Elderberry
Sambucus nigra subsp. cerulea
Adoxaceae, Caprifoliaceae · broadleaf · native
Blue elderberry is a large, spreading deciduous (or nearly evergreen in mild climates) shrub or small tree reaching 15-30 feet, native from British Columbia east to Montana and south to California and New Mexico. You will recognize it by its opposite, pinnately compound leaves (15-25 cm long) with 5-7 (occasionally 9) narrow leaflets.
Blue elderberry adapts to a range of soil conditions from wet to dry, though it prefers moist sites. Provide full sun to part shade and occasional summer water during establishment. The plant responds well to renewal pruning and recovers vigorously from cutting. The berries are traditional food for Native Americans and are excellent for syrups, jams, and liqueurs.
