Attractive and pleasing to the eye, Lonicera involucrata (Twinberry Honeysuckle) is a long-lived deciduous shrub with sturdy shoots covered with opposite, bright green, elliptical leaves, 5 in. long (12 cm). In early spring to late summer, depending on locations, small, dainty yellow flowers, 1 in. long (2.5 cm), appear in dangling pairs surrounded by two leafy bracts. The bracts turn from green to a brilliant dark red in late summer as fruits ripen. The flowers give way to pairs of small plump purple or black berries that are unpleasantly bitter tasting. Great for wildlife, the flowers are a source of nectar for hummingbirds and butterflies. The berries are eaten by bears, small mammals, game birds including quail and grouse, and songbirds. Native to northern and western North America, Twinberry Honeysuckle grows in moist forest openings, swamps, streamsides, and meadow edges, ranging in elevation from sea level along the Pacific Coast to subalpine sites in the mountains. Twinberry Honeysuckle is a valuable shrub for streambank erosion control and restoration of riparian areas, swamps, bogs, moist woodlands, scrub-shrub wetlands, and sandy coastal areas within its native range. Like many honeysuckles, Twinberry Honeysuckle is also an attractive garden ornamental. Its flowers are most welcomed in summer when many other plants have finished blooming.
