Japanese Kerria

Japanese Kerria (Kerria japonica)

Japanese Kerria (Kerria japonica) is a graceful, deciduous flowering shrub known for its vibrant yellow blooms and arching green stems. Native to China and Japan, this old-fashioned favorite brings cheerful spring color and textural elegance to shady borders, woodland gardens, and informal landscapes. It�s especially prized for blooming in low-light conditions where few other shrubs perform as well.

Distinctive Features

Kerria japonica produces a profusion of bright yellow, rose-like flowers in mid to late spring, often continuing to sporadically rebloom throughout the summer. The simple, serrated green leaves turn soft yellow in fall, while the slender, lime-green stems provide winter interest even after leaf drop. Reaching 5 to 7 feet tall and wide, it forms a loose, fountain-like mass that adds movement and softness to any setting.
