Rubus cuneifolius

Sand blackberry is a shrub in the rose (Rosaceae) family and is a deciduous to semi-evergreen shrub producing clusters of erect, rarely arching, densely-prickly, biennial stems from a woody rootstock This plant can be found in the coastal plains and sporadically in the Piedmont of NC. Sand blackberry is also present in the coastal areas of LA to NH and also in some inland eastern states and is often found in sandy thickets, woodland edges and fields.

The 2-5 foot canes do not bloom or fruit the first year but flower in spring and produce fruit the second year, then die down. The showy white flowers appear in spring and are followed by purple/black edible berries. The plant is loaded with prickles on the canes and stems. The leaves are compound and with a distinctly pleated look.

This plant prefers an acidic sandy loam in partial to full sun in moist but well-drained soil. Use in the edible garden or a naturalized or woodland area. It is a high-value plant for wildlife and provides food and cover year-long.

Information on blackberry cultivation for home gardeners is available in the NC State Extension publication Blackberries for the Home Garden.

Insects, Diseases, and Other Plant Problems: Plants in this genus are notably susceptible to honey fungus.  Thripes may be a problem. Can become aggressive and difficult to eliminate. Because it is so successful and can spread easily, use caution when selecting a planting site. Herbicides may be required to completely eliminate the plant. In South Africa and Australia, it has become invasive.
