About Devon blackberry
Rubus dumnoniensis, also known as the Western Bramble, is a deciduous thorny shrub native to Western Europe. It produces abundant edible fruits similar to blackberries, which are glossy black and have a sweet-tart flavor. It is ideal for creating defensive hedges, for soil restoration, or simply as a fruit-bearing plant in rustic or wild gardens.
Native range
Western Europe, including the British Isles
Care tips
It prefers full sun to partial shade exposure and well-drained soils, although it is quite tolerant of different soil types. Watering should be regular during fruiting and dry periods, but avoid waterlogging. Annually prune canes that have already fruited to encourage the growth of new productive branches. A common mistake is not pruning, which leads to lower fruit production and unruly growth.
