Although red-flowering currant (Ribes sanguineum) is a deciduous shrub, it offers year round appeal and habitat, making it a favorite among Pacific Northwest gardeners and wildlife, alike. Not one December goes by that I don’t marvel at its ability to hold onto many of its seasonally colorful leaves until the solstice or beyond, and this year was no exception. Just a short while later — following barely two months of downtime in the new year — strikingly gorgeous flower clusters burst forth prolifically at the same time that fresh leaves emerge. No wonder another of its common names is “winter currant.” Fast forward a few more months, and dark dusty-blue berries, a favorite of many bird species, will adorn this multi-stemmed shrub.
The sole genus in the Grossulariaceae family, Ribes means ‘currant’ in medieval Latin. One of about 30 currant and gooseberry species in the Northwest, sanguineum refers to the reddish color of the flowers. It’s one of those native plants that had to be chaperoned by Scottish botanist David Douglas to Britain—where it was introduced into cultivation in the 1820s—before it acquired a return transatlantic ticket to popularity with gardeners on its home turf. Not too small or huge, it can usually find a home in places that offer well-drained soil and at least a quarter day of sun.
How it grows
Red-flowering currant naturally occurs at the edge of forests as well as open, rocky slopes and disturbed sites, at low to middle elevations from southwest British Columbia into Washington and Oregon between the Pacific coast and the Cascades, and as far south as central California.
Wildlife value
Pendulous flower clusters, which consist of numerous lightly fragrant, pink to reddish tubular flowers, bloom in profusion along this shrub’s many stems. They offer nectar and pollen at a time when early-emerging pollinators—such as queen bumble bees who must secure a nest and provide for offspring all by themselves—have little else to eat. The early blossoms are also attractive to birds, especially hummingbirds, but also bushtits, making this species a hub of wildlife activity for well over a month. Later on, when berries ripen as summer wanes, birds such as American robins and cedar waxwings (pictured, below) feast; we can also eat them but they are rather tasteless. The small, lobed leaves may provide food for zephyr (Polygonia gracilis zephyrus), Ceanothus silkmoth (Hyalophora euryalus), and other butterfly and moth larvae, which in turn supply food for insectivorous birds.
Try it at home
Red-flowering currant prefers sun to part sun, and well-drained soil. While tolerant of clay soils, it doesn’t do well on poorly drained sites. Useful for erosion control on slopes, it may eventually form a thicket, which is helpful for wildlife that needs cover.
Mature size varies from around six to ten feet tall; width is typically similar, so do allow it enough space. A fast grower, it may reach four or five feet in just a few years and even produce blossoms as well. If you’re looking to use this shrub in a border, space them five to ten feet apart (on the low end if you want some density and overlap). Although this shrub is quite drought tolerant when established (after two to three years), water it deeply but infrequently in the hot summer months thereafter, especially if your site receives a lot of sun or reflected heat from buildings or fencing, or if drainage is quick. Plant in fall for best results.
The only downside to this lovely shrub is its relatively short life: typically just 20 to 30 years. But replacement is easy since it readily self-sows. Thus, propagation is best achieved via self-sown seed, which are easily dispersed by birds or fall to the ground below. If you want to DIY, collect seeds as soon as fruit is ripe in mid to late summer, remove the pulp and dry them in a shaded place; then sow in autumn (outdoors to allow for stratification). Seed reportedly has a long shelf life if stored in a cool/dry/dark place.
Grab a partner
Since red-flowering currant grows in a fairly wide range of habitats, there are a number of plants with which it interacts in intact ecosystems. For best ecological and gardening results, choose associated native plants that live in communities that currently grow or likely would have grown in your immediate area. In the Pacific Northwest, some of the plants that red-flowering closely associates with include Douglas-fir, bigleaf maple, madrone, bitter cherry, oceanspray, vine maple, elderberry, mock orange, serviceberry, manzanita, salal, sword fern, kinnikinnick, and others.
Buy plants propagated from source material that originated as close as possible to your site. Using such “local genotypes” helps ensure that you get plants that are well adapted to your area and preserves the genetic diversity that helps plants (and animals) adapt to changing conditions. Ask growers and nurseries about their sources if you’re unsure.
Although many cultivars—with a range of flower color—have been developed, it’s best to choose true species or varieties found in nature. A related species for very moist places is wild gooseberry (Ribes divaricatum), which has edible fruit.
