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.
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 ...
