Kerria japonica 'Honshu' - Japanese rose

Kerria japonica - Japanese Kerria Family: Rosaceae (Ker-ria: named for William Kerr, Kew Gardener and Collector) Kerria japonica is a hardy (Zone 5) deciduous shrub that matures at 3 to 5 feet in height. It's a dense mounded plant with numerous slender, zigzagging branches that emerge at ground level. The beauty of Kerria is found in its flowers, stems and foliage. The bright yellow flowers are noticeably reminiscent of an old fashioned rose with its 5 petals. The flowers clearly make this plant a member of the Rosaceae family. In early spring, before the leaves emerge, the numerous yellow flowers create a colorful show. As an added benefit, Kerria will often rebloom off and on all summer long. The effect is beautiful and rewarding. Kerria is also blessed with attractive ornamental stems. From autumn to spring, its bright kelly green stems create a wonderful, fresh impression.

Honshu A gem of a Kerria selected by Kai Mei and David Parks of Camelia Forest Nursery. Large, rich yellow, single blooms appear in early spring and repeat during the summer. Attractive bright green stems. Blooms and thrives in partial shade.
