A black raspberry is a small fruit (botanically an aggregate fruit) that weighs between one and two grams. Almost all commercial production of black raspberries is from developed cultivars of Rubus occidentalis. Oregon accounts for over 90% of black raspberry production in the United States.
Black raspberry plants yield significantly less fruit than their red counterparts and also commonly suffer from a raspberry mosaic disease complex that gives them shorter lifespans than other cane berry plants. Because of this, they can be costly to produce on a large scale.
Famous quotes containing the word black:
“In writing biography, fact and fiction shouldn’t be mixed. And if they are, the fictional points should be printed in red ink, the facts printed in black ink.”
—Catherine Drinker Bowen (1897–1973)
