Rubus ulmifolius, commonly known as elmleaf blackberry or thornless blackberry, is a semi-deciduous shrub native to a variety of habitats including open woodlands, forest edges, and riparian areas across Europe and North Africa. It has also become naturalized in parts of the United States, Australia, and South America. This robust plant can grow up to 16 feet tall and is characterized by its arching canes and palmately compound leaves with woolly undersides. The shrub produces pink to white flowers in late spring to early summer, followed by edible blackberries that are attractive to both humans and wildlife.

Elmleaf blackberry is valued for its fruit production and is often used in fruit gardens and for naturalistic plantings. It can also provide erosion control on slopes due to its spreading habit. In cultivation, it prefers full sun to part shade, moist but well-drained soils, and it tolerates a range of soil types. While it is known for being less aggressive than other blackberry species, it can still spread via root suckers, potentially becoming problematic. Regular pruning is recommended to maintain its shape and promote fruiting.CC BY-SA 4.0
