Marvin Pritts, a professor of horticulture at Cornell University, asserts that less than 0.1% of Americans have likely ever eaten a blackcurrant. [3] Their rarity in the United States contrasts with the situation in Europe, which produces 99.1% of the world's blackcurrant crop, and where blackcurrant is a popular flavor of squash (cordial).

Ribes (/ ˈ r aɪ b iː z /) [5] is a genus of about 200 known species of flowering plants, most of them native to the temperate regions of the Northern Hemisphere. [2] The species may be known as various kinds of currants, such as redcurrants, blackcurrants, and whitecurrants, or as gooseberries, and some are cultivated for their edible fruit or as ornamental plants.

Although effective in theory, removal of currants is rarely successful ...
Ribes americanum is a North American species of flowering plant in the gooseberry family known as wild black currant, [1] [3] [4] [5] American black currant, [6] and eastern black currant. [7] It is widespread in much of Canada (from Alberta to Nova Scotia ) and the northern United States (from New England to Washington , with additional ...
The species is divided into two varieties, [4] each known simultaneously as northern black currants, and by their own individual common, and scientific names; the type variety, R. h. var. hudsonianum, is also known as the Hudson Bay currant; [4] [7] whereas R. h. var. petiolare is also known as the western black currant.
Inflorescence. The jostaberry (Ribes × nidigrolaria) is a complex-cross fruit bush in the genus Ribes, involving three original species, the blackcurrant R. nigrum, the North American coastal black gooseberry R. divaricatum, and the European gooseberry R. uva-crispa. [1]
