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.
