description Black Raspberry (Rubus occidentalis) Overview
Black raspberry, Rubus occidentalis, is a deciduous bramble in the rose family native to eastern North America. Its dark aggregate fruit resembles a blackberry, but a ripe black raspberry separates cleanly from the receptacle and is therefore hollow at the center when picked. The plant grows on arching, thorny canes and is cultivated on a limited commercial scale, with Oregon serving as an important center of United States production.
help Black Raspberry (Rubus occidentalis) FAQ
How can you tell a black raspberry from a blackberry?
A ripe black raspberry pulls away from its receptacle and leaves a hollow center. A blackberry keeps its receptacle inside the picked fruit, so its core appears solid rather than hollow.
Where is Rubus occidentalis native?
Rubus occidentalis is native to eastern North America and commonly grows along woodland edges and disturbed ground. It belongs to the rose family, Rosaceae, and grows as a thorny deciduous bramble.
Why are fresh black raspberries difficult to find in stores?
The berries are soft, highly perishable, and more easily damaged during transport than many commercial fruits. Much of the crop is therefore sold frozen, processed into preserves, or used in products such as Oregon black raspberry puree.
Can black raspberries and red raspberries cross-pollinate safely in a garden?
They can grow near one another, but gardeners often separate black raspberries from other brambles to reduce the spread of viral diseases. Aphids can carry viruses from apparently healthy red raspberries to more susceptible black raspberry plants.
