Kerria japonica ‘Pleniflora’ is a vigorous, deciduous spring flowering shrub, perfect for brightening a dark corner or north-facing wall. It will grow almost anywhere and soon develops into a thicket of tall, graceful stems with suckers growing from the creeping roots. Double, yellow flowers burst out from mid- to late spring which are beautifully surrounded by bright green, oval leaves. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
