Uses
Bird and Pollinator Support
WildlifeThe white flowers attract bees, butterflies, and other pollinators in spring, while the abundant blue-black berries provide essential fall and winter food for migratory birds including cedar waxwings, robins, and thrushes. [source]
Hedging and Privacy Screens
HouseholdDense branching and moderate-to-tall growth habit (6-10 feet) make Smooth Arrowwood excellent for living hedges and screening unsightly views. Can be pruned for formal shapes or left natural. [source]
Edible Berries

Harvest Tips
Smooth Arrowwood is ornamental and ecological rather than harvested. Berries can be collected for wildlife observation or to propagate new plants. Allow berries to fully ripen to dark blue-black in late summer/early fall before harvesting seeds. Cut flowering stems for fresh arrangements in late spring when flowers are fully open.
