About

Rubus occidentalis is a species of bramble native to eastern North America. Its common name black raspberry is shared with other closely related species. Other names include bear's eye blackberry, black cap, black cap raspberry, and scotch cap.

How to grow it

A center for black raspberry cultivation is in the Willamette Valley of Oregon. The main cultivar is 'Munger'. Other cultivars include 'Allen', 'Blackhawk', 'Bristol', 'Cumberland', 'Dundee', 'Hanover', 'Huron', 'Jewel', 'John Robertson', 'Logan', 'Macblack', 'Morrison', 'Munger', and 'Plum Farmer'. The plants are summer tipped by hand, mechanically pruned in winter and then machine harvested. The yields are generally low per acre and this is why the fruits are often expensive.

The species has been used in the breeding of many Rubus hybrids; those between red and black raspberries are common under the name purple raspberries; 'Brandywine', 'Royalty', and 'Estate' are examples of purple raspberry cultivars. Wild purple raspberries have also been found in various places in northeastern North America where the two parental species co-occur and occasionally hybridize naturally.

Where it grows

The plant is native to eastern North America, with a range as far east as New Brunswick, as far west as Nebraska, as far north as Quebec, and as far south as Mississippi. It grows in disturbed areas, especially those that are logged or cut. It is also found in meadows, and near streams and lakes, trails or roadways.

Uses

The berries are edible raw and can be made into jams and jellies. They have a high content of anthocyanins.
