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).

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]
Aphelenchoides ritzemabosi (black currant nematode, chrysanthemum foliar nematode, chrysanthemum leaf nematode, chrysanthemum nematode, chrysanthemum foliar eelworm) is a plant pathogenic nematode. It was first scientifically described in 1890 in England.
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.
