About Wild blackberry
Rubus vallisparsus, commonly known as Ronce, is a deciduous shrub belonging to the Rosaceae family, native to North America. It is characterized by its thorny stems, dark green compound leaves, and white or pink flowers that develop into edible, blackberry-like fruits. It is ideal for creating defensive hedges, for slope stabilization, or as part of a wild and edible garden.
Care tips
This species prefers full sun to partial shade and adapts to a wide range of soils, though it favors well-drained and slightly acidic ones. Watering should be regular during dry periods, especially in its first year, to ensure good establishment. A common mistake is not pruning old canes (those that have already fruited) to ground level in winter to encourage new shoot growth and better fruit production. Avoid waterlogging, as it can lead to root rot.
