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.


KOELREUTERIA.

KOELREUTERIA PANICULATA.--Northern China, 1763. Whether for its foliage
or flowers, this small-growing tree is worthy of a place. Though of
rather irregular growth, the beautiful foliage and large panicles of
yellowish flowers, which stand well above the leaves, make the shrub
(for it does not in this country attain to tree height), one of
particular interest, and a valuable aid in ornamental planting. In a
sheltered corner, and planted in rich soil, it grows and flowers freely.


LABURNUM.

LABURNUM ADAMI (_syn Cytisus Adami_).--A graft hybrid form between the
common Laburnum and Cytisus purpureus, the result being flowers of the
Laburnum, the true Cytisus purpureus, and the graft hybrid between the
two. It was raised by Jean Louis Adam in 1825. It is a curious and
distinct tree, worthy of culture if only for the production of three
distinct kinds of flowers on the same plant.
