Ribes laxiflorum is a species of currant known by the common names trailing black currant, and spreading currant. It is native to western North America from Alaska and northeastern Canada to far northern California to Colorado and New Mexico; it is also known from Siberia. Its habitat includes moist mountain forests, open clearings, streambanks, and the borders of mountain roads.
It is a spreading, trailing shrub usually growing one half to one meter in height. It has been known to take a somewhat vinelike form in appropriate shady habitat with nearby supports, climbing to seven meters in maximum length. It has fuzzy, glandular stems lacking spines and prickles. The hairy, glandular, maple-shaped leaves are up to 10 centimeters long and deeply divided into several pointed lobes lined with dull teeth. The inflorescence is a mostly erect raceme of up to eight flowers. The distinctive flower has five greenish, purplish, or red sepals which are often curved back at the tips. At the center is a corolla of five red or pink petals each measuring a millimeter long, narrow at the base and wider or club-shaped at the tip. Inside the corolla are five red stamens tipped with whitish anthers. The fruit is a purple-black berry measuring four to fourteen millimeters wide which is waxy, hairy, or bristly in texture.
