American elderberry (Sambucus canadensis) is a fast-growing shrub native to the eastern half of North America. It prefers wet soils, but is not limited to them. Both the flower and the berries are edible. The fruit are often used in wine, jam, jelly, syrup, and beer. Aside from attracting many native pollinators, it is also a host plant for three dozen caterpillars.
