Trailing Black Currant (Ribes laxiflorum) Conservation Status Review
Review Date =
Trailing Black Currant is a prostrate to upright shrub usually less than 1 m high, with branches that may be pubescent when young but become smooth and deep reddish-brown. Leaves are mostly 4-8 cm across and usually wider than long, and 5-lobed nearly half the length. Infloresences are loosely 8-18 flowered, erect or ascending, and copiously pubescent with stalked glands throughout. Flowers are shallowly bowl-shaped, with a pubescent calyx that is greenish-white too deep red or purplish, and petals that are red to purplish. The berry is purplish-black and glandular-bristly.
Possibly flowering in May, fruit persisting through summer.
Distinguished from the other species of Ribes that lack spines and bristles by the saucer-shaped base of the flower and glandular fruit.
