Flowering currant is a deciduous shrub native to the Pacific coast of western North America, from British Columbia south through Washington and Oregon to coastal California (as far south as Santa Barbara County), with a marginal inland presence in Idaho and a southern outpost on Guadalupe Island, Mexico. Its bold dangling racemes of deep-pink to crimson flowers open in early spring, often before the leaves, making it one of the most conspicuous late-winter shrubs in mild gardens. The honest catch is threefold: it is a confirmed alternate host of white pine blister rust (a serious pathogen of five-needled pines), its blue-black berries are edible but notably insipid, and it has become an established invasive weed in New Zealand (where it forms dense stands excluding native species) and is a more minor, localized weed in Tasmania.

An upright, multi-stemmed, rhizomatous deciduous shrub of the western U.S. and Canada, named for its showy, fragrant yellow-to-orange spring flowers. Glossy lobed leaves turn reddish-purple in fall, and the spring bloom gives way to edible black currants by mid to late summer. Tough and adaptable — it tolerates dry to seasonally flooded soils, poor and clay soils, drought, and erosion, and the flowers and fruit feed hummingbirds, butterflies, and birds.
