Blackcurrant Blackcurrant The blackcurrant or black currant ("Ribes nigrum") is a woody shrub in the family Grossulariaceae grown for its berries. It is native to temperate parts of central and northern Europe and northern Asia where it prefers damp fertile soils and is widely cultivated both commercially and domestically. It is winterhardy, but cold weather at flowering time during the spring reduces the size of the crop. Bunches of small, glossy black fruit develop along the stems in the summer and can be harvested by hand or by machine. The raw fruit is particularly rich in vitamin C and polyphenol phytochemicals.
Empetrum nigrum Empetrum nigrum Empetrum nigrum, crowberry, black crowberry, or, in western Alaska, blackberry, is a flowering plant species in the heather family Ericaceae with a near circumboreal distribution in the northern hemisphere. It is also native in the Falkland Islands. It is usually dioecious, but there is a bisexual tetraploid subspecies, Empetrum nigrum" ssp. "hermaphroditum, that occurs in more northerly locations and at higher altitude. Evolutionary biologists have explained the striking geographic distribution of crowberries as a result of long-distance migratory birds dispersing seeds from one pole to the other. The metabolism and photosynthetic parameters of "Empetrum" can be altered in
