Although it is a sweeter and less pigmented variant of the redcurrant, not a separate botanical species, it is sometimes marketed with names such as R. sativum or R. silvestre, or sold as a different fruit. Currant bushes prefer partial to full sunlight and can grow in most types of soil. [11]
The flowers are produced in early spring at the same time as the leaves emerge, on dangling racemes 3–7 cm (1–3 in) long of 5–30 flowers; each flower is 5–10 millimetres (1 ⁄ 4 – 3 ⁄ 8 in) in diameter, with five red, pink, or white [6] petals. The fruit is a dark purple oval berry about 1 cm (3 ⁄ 8 in) long; it has an insipid ...
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.
Ribes triste, known as the northern redcurrant, [2] swamp redcurrant, or wild redcurrant, [3] is an Asian and North American shrub in the gooseberry family. Description [ edit ]
Cecidophyopsis ribis is an eriophyid mite which is best known for being a plant parasite, a pest of Ribes species, the genus that includes gooseberries and blackcurrants. It is commonly known as the blackcurrant gall mite or big bud mite. It feeds on the plants' buds, forming galls, and transmits a virus which causes blackcurrant reversion ...

Soon after the leaves open in the spring, the galls are yellow and turn red by the early summer. Leaves can also be crinkled, with a colony of yellow-greenish aphids living in the hairy depressions on the underside of the leaves. Cultivars of red currants are preferred. Adults are 1–2 millimetres (0.039–0.079 in) long.
Because the infection moves from currant plants, to pines, and back again, it cannot continue to exist without its secondary host. Although effective in theory, removal of currants is rarely successful in practice, as they readily re-grow from small pieces of root left in the soil, and the seeds are very widely spread in birds' droppings.
