Kerria japonica 'Pleniflora'
Double-flowered Japanese Kerria, Japanese Kerria
Grown for its sunny flowers and its evergreen stems, Japanese kerria is a suckering deciduous shrub from China and Japan. The double-flowered kerria is popular for its bright yellow pompon flowers in late spring that last longer than those of other cultivars. Its also has taller, more erect stems. The oval, toothed, bright green leaves turn yellow in fall. Plants sometimes rebloom in summer.
This long-lived, hardy, carefree shrub prefers full to partial sun and thrives in fertile to average, well-drained soil. Once established, plants will tolerate moderate periods of drought. Since its stems are evergreen, Japanese kerria adds a spot of color to otherwise dormant winter borders. This plant needs room to roam; try it in a shrub border, or grow it as a feature plant. The colorful stems are popular in winter flower arrangements.
