Rubus ×setosus, commonly known as Setose Blackberry, is a deciduous subshrub native to open woodlands and forest edges in the Northeastern USA and Eastern Canada. It typically grows to a height of 2-5 feet (0.6-1.5 meters) and a width of 3-6 feet (0.9-1.8 meters). The plant is characterized by its arching canes covered with fine bristles and its compound leaves with toothed leaflets. During the summer, it produces small, showy purple flowers followed by edible blackberries that are attractive to wildlife and can be used in culinary applications.

Setose Blackberry is valued for its fruit production and as a naturalizing plant in garden settings. It is often used in fruit gardens, as a border plant, or for wildlife habitats. This blackberry prefers part shade but can tolerate full sun if provided with adequate moisture. It requires soils with medium drainage and benefits from mulching to retain soil moisture and suppress weeds. While it is generally easy to maintain, it can become invasive if not managed properly, spreading through its rhizomes and self-seeding. Gardeners should be aware of its potential to spread and take measures to control its growth if necessary.CC BY-SA 4.0
