Flowers: many in elongate clusters up to 17 cm long. Flower stalks slender, jointed below the flowers, 3-8 mm long. Ovary conical, covered with stalkless glands. Calyx white, thickly crisp-short-hairy, widely flared and somewhat saucer-shaped, 1-1.5 mm long, lined, the 5 sepals obovate, 3-4 mm long, spreading. The 5 petals white, about 1.5 mm long, wedge-shaped upward. The 5 stamens inserted below but about equaling the petals. Filaments hairless, anthers oval, about 0.7 mm long. Styles about 2 mm long, joined slightly more than half their length at flowering.

The fruits of northern black currant are edible raw or cooked. They don't taste very good raw, however they can be made into black currant jelly or jam, which is delicious with meat, fish or bannock.
A decoction of the stem sections, used alone or with wild gooseberry stems has been used to treat sickness after childbirth. The raw fruits have been eaten as a treatment for colds. A decoction of the stems and leaves has been used in the treatment of colds, sore throats and stomach complaints, and has also been taken as a general panacea to treat all types of sickness and also tuberculosis. Large quantities of northern black currants can be strongly purgative, and can even cause vomiting at the same time but not if they are mixed with cranberries. The Thompson tribe believed that this shrub had a calming effect on children, so sprigs of it were often put in baby carriers.
