Life History
Wineberry, also called Wine Raspberry, is a multi-stemmed, spiny, small shrub that can grow to 9 ft. (2.75 m) and is a member of the Rosaceae (Rose) family. It spreads through seed dispersal via birds and mammals as well as vegetative spread when long canes take root where they touch the ground. Though useful to berry culture, Wineberry is an aggressive plant forming large, dense thickets and is a threat to native plants in a variety of habitats. Wineberry is sometimes confused with the common blackberry and raspberry of the same family.Habitat
Like other members of Rubus, wineberry prefers moist conditions and adequate sunlight. Many species of birds and mammals use the brambles for nesting and shelter.Origin and Distribution
Wine raspberry is native to eastern Asia and was first introduced into the United States in 1890 as breeding stock for new raspberry cultivars.
