Twinberry is a native shrub found in western North America from Alaska to Mexico. It grows in moist forests, clearings, riparian habitats, swamps and thickets. Twinberry is a woody shrub that reaches 6-12 feet tall and wide with shiny green leaves. It blooms from spring to summer with tubular yellow flowers with red inside that produce showy dark purple berries surrounded by red bracts. The berries are bitter and slightly toxic, attracting birds but not being edible for humans. Twinberry is often used in gardens in moist areas and provides good habitat and cover for wildlife while its foliage and fruits attract hummingbirds, butterflies, bees and birds. It requires full sun
