KERRIA JAPONICA (syn Corchorus japonicus).—Japan, 1700. A Japanese shrub, the double-flowered variety of which, K. japonica flore-pleno, is one of our commonest wall plants. The orange-yellow flowers, produced in great rosettes, are highly ornamental, and have earned for the shrub a well-known name. It succeeds well almost anywhere, and, though usually seen as a wall plant, is perfectly hardy, and forms a neat shrub for the open border. There is a form in which the leaves are variegated, and known under the name of K. japonica variegata.
