Shrub/Tree Indiana Native Forestiera acuminata [Swamp Privet] The Swamp Privet is a large shrub typically found near swamps, floodplains, wet woods and marshes. Purple-black fruits (drupes) ripen during late summer and is a food source for water fowl, such as ducks. Forestiera acumunata is dioecious, so one would need a male and female for the shrub to produce its fruit. Leaves are a dark green and looks evergreen from a glance, yet turns a golden yellow in fall.
