Description
Ribes bracteosum is a deciduous shrub reaching heights of 2–3 m (6–10 ft). The stems are brownish and bear short, stout spines near the base. Leaves are palmately lobed, typically with five lobes, measuring 3–7 cm (1.2–2.8 in) across; the leaf surface is covered with glandular hairs that give a slightly sticky feel.
The inflorescences are terminal racemes 5–10 cm (2–4 in) long, composed of numerous small, pink‑white to pale lavender flowers. Each flower has five reflexed petals and a prominent central cluster of stamens. Flowering occurs in early summer (May–June).
Fruits are small berries, 5–8 mm in diameter, initially green, maturing to a dark purple‑black color. The berries are edible but have a strong, often unpleasant odor, which is the source of the common name “stink currant.”
Distribution and habitat
Ribes bracteosum is native to the Pacific Northwest of North America. Its range extends from southern British Columbia through Washington, Oregon, and northern California. The species is typically found in moist, shaded environments such as coniferous forest understories, riparian zones, and along stream banks, from sea level to elevations of about 1,800 m (6,000 ft).
Ecology
The flowers are visited by a variety of pollinators, including bees and flies. The berries provide a food source for birds and small mammals, which also aid in seed dispersal. The shrub contributes to understory diversity and can tolerate a range of soil moisture conditions, though it prefers well‑drained, humus‑rich substrates.
Uses
- Traditional uses: Indigenous peoples of the region have historically harvested the berries for food, sometimes processing them to reduce the strong odor.
- Ornamental horticulture: The plant is occasionally cultivated for its attractive foliage and racemes of flowers, especially in native‑plant gardens and restoration projects.
- Wildlife: Provides browse for deer and cover for small mammals; berries support avian species.
Conservation status
The species is generally considered secure across most of its range and is not listed as threatened or endangered by major conservation agencies. Localized impacts may occur from habitat alteration, such as logging or development of riparian zones.
