Ribes lacustre, commonly known as swamp currant, is a deciduous shrub native to western North America. It is a member of the Grossulariaceae family, which also includes gooseberries. This species is often found in moist, shaded environments, contributing to the biodiversity of its ecosystems. The swamp currant typically grows to a height of 1 to 3 meters (3 to 10 feet), forming a dense, spreading thicket. Its stems are armed with sharp, bristly prickles, a characteristic that helps deter herbivores. The leaves are palmately lobed, usually with five lobes, and are arranged alternately on the stems. They are typically 3 to 7 centimeters (1 to 3 inches) wide, with serrated margins and a somewhat sticky, glandular surface that emits a pungent aroma when crushed. In autumn, the foliage may turn shades of yellow or reddish-brown before dropping. Flowering occurs in late spring to early summer, with racemes of small, inconspicuous flowers. Each flower is typically 3 to 5 millimeters long and is pendulous, with petals and sepals that are often greenish or purplish-red. The flowers are borne in drooping clusters, usually 3 to 8 centimeters (1 to 3 inches) long, and are attractive to pollinators. Following pollination, the plant produces clusters of small, spherical berries. These berries are typically dark purple to black when ripe, about 6 to 10 millimeters in diameter, and are covered in glandular hairs, giving them a bristly appearance. The fruit is edible, with a tart flavor, and is a food source for various wildlife. Ribes lacustre is widely distributed across western North America, from Alaska and Canada south to California and Colorado. It thrives in moist to wet habitats, commonly found in bogs, fens, wet meadows, along stream banks, and in coniferous or mixed forests, often in shaded understories. It prefers acidic to neutral soils and can tolerate a range of soil types as long as adequate moisture is present. While it is not widely cultivated, its tolerance for wet conditions and shade makes it a potential candidate for naturalistic landscaping in suitable environments. The berries of swamp currant have been historically used by indigenous peoples for food, often consumed fresh or dried. Ecologically, Ribes lacustre plays a role in its habitat by providing food and shelter for wildlife. Birds and small mammals consume the berries, and the dense shrubbery offers protection. The plant's ability to grow in wet, shaded areas contributes to soil stabilization and habitat structure in riparian zones and wetlands. While not a significant agricultural crop, its presence is indicative of healthy, moist ecosystems. An interesting characteristic of this species is its glandular pubescence, which gives the leaves and fruits a sticky, somewhat hairy texture and a distinctive scent.
