Rubus phoenicolasius

The species was introduced to Europe and North America as an ornamental plant and for its potential in breeding hybrid raspberries.

[7] As a fruit develops, it is surrounded by a protective calyx covered in hairs that exude tiny drops of sticky fluid.

Also, unlike carnivorous plants, wineberry grows in nutrient-rich soil, so it need not resort to insect proteins as a source of nitrogen.

Wineberries grow vigorously and can form extensive, dense thickets that displace many native species.

[13][14] Wineberries can be found in many habitats, such as forest, fields, stream banks, and wetland edges, as well as open woods.

[13] The wineberry is listed as a noxious weed by both Connecticut and New York where its possession and sale are prohibited by law.
