Synonym(s): Japanese wineberry

Wine raspberry is a multi-stemmed, spiny, small shrub that invades open areas throughout the eastern United States. The canes have small spines and the entire plant is covered in minute, glandular, reddish hairs. Canes can, under favorable conditions, grow to 9 ft. (2.7 m) in length. The alternate leaves are compound with three heart-shaped, toothed leaflets. The undersides of the leaflets are silvery-white and very hairy. Small, white, 5-petaled flowers develop in the spring and give way to tasty, red, raspberry-like fruit. Wine raspberry invades moist, open areas such as fields, roadsides, forest margins, open forests and prairies. It reproduces by seed (which are readily dispersed by animals) and root nodes. New plants can grow from the canes touching the ground. It can form extensive, dense thickets that displace native vegetation and restrict light to the ground cover in open areas. Wine raspberry is native to eastern Asia and was first introduced into the United States in 1890 as breeding stock for new raspberry cultivars.
