About Rubus cubitans
Rubus cubitans, commonly known as sprawling dewberry, is a low-growing perennial plant that forms a dense groundcover. Its trailing stems bear attractive green leaves and white flowers, which are followed by small, edible, blackberry-like fruits. It is ideal for groundcover in gardens, erosion control on slopes, or as an ornamental plant in borders and rockeries.
Native range
Southeastern United States
Care tips
It prefers full sun to partial shade and well-drained soils, though it is quite tolerant of different soil types. Water regularly during dry periods, especially when establishing, but avoid waterlogging as it is susceptible to root rot. A common mistake is not pruning: annual pruning in early spring helps control its vigorous growth and encourages better fruiting. It does not require excessive fertilization; a light compost in spring is sufficient.
