Lonicera involucrata
Black Twinberry is a member of the Honeysuckle family, forming a beautifully arching tall and wide upright shrub. Seemingly thousands of pairs of yellow, tubular flowers emerge in April and continue blooming all summer long, providing nectar to countless species of insect pollinators and making it a magnet for hummingbirds. As the season progresses, the flowers become encased in showy red bracts that eventually hold it’s shiny black, “twin” berries, the namesake of this lovely garden shrub.
