Plant details

Also known as Jew's mallow or quite simply as Kerria, this is a vigorous, deciduous spring flowering shrub. 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 and are beautifully surrounded by bright green, oval leaves. It is best kept out of direct sunlight to avoid bleaching the flowers. It is ideal for illuminating a dark corner or north-facing wall. Thin out old shoots after flowering and propgate by softwood cuttings in summer or by division in autumn. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
