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 its shiny black, “twin” berries, the namesake of this lovely garden shrub.

Gardening with Black Twinberry: This fast growing shrub is carefree when planted in the right place. Be sure to give it a part to full sun location with moist soil, such as a sunny raingarden. It can even tolerate seasonal flooding and will help stabilize soils in these areas. Since it is adored by hummingbirds, place it in an area where it can be viewed from a window to enjoy entertainment all summer long.
