ke, and let the smaller branches grow at will, the result
being a fountain of yellow flowers. After flowering in the greenhouse,
cut back the shoots hard, leaving only an eye or two at the base. These
eyes will break up and produce flowering shoots for another year. By
this method of treatment the same plants may be kept for many years,
provided they are carefully attended to and given occasional doses of
liquid manure during the summer.

HYDRANGEA.--The many varieties of the common Hydrangea are all valuable
for the greenhouse, particularly _Cyanoclada_, _Mariesii_, _Rosea_,
_Stellata_, and Thomas Hogg. To obtain small flowering plants the
cuttings are struck in spring or early summer, grown on freely for a
time, and well ripened by full exposure to air and sunshine before
autumn. Plants grown in this way readily respond to a little heat in the
spring. Larger specimens, too, may be brought on in the same way. The
Japanese _H. paniculata grandiflora_ needs quite different treatment,
the plants being generally grown in the open ground, from whence they
are lifted and potted in the autumn. Before potting prune the long,
wand-like shoots back hard, leaving only about two eyes at the base. By
so doing the plants are kept dwarfer, and the flower heads are larger
than if no pruning were done. By some the Hydrangea is grown as a
standard, and is very effective when in beauty.

ITEA VIRGINICA.--A neat little bush, about a yard high, with dense
spikes of white flowers. It needs a sunny spot in a cool and moist soil,
and under these conditions will flower freely if carefully lifted in
the autumn and potted. It must not suffer from dryness afterwards. No
pruning is necessary.

JAMESIA AMERICANA.--A pretty little white-flowered shrub from the Rocky
Mountains. It will bloom freely under glass, but must not be forced
hard; it may be treated in the same way as the Itea.

KALMIA.--All the Kalmias are good pot shrubs. The roots are dense and
wig-like, reminding one of those of a Rhododendron, so that well-budded
plants can be lifted in the autumn and potted without risk. They must be
brought on gradually in a cool house, and never suffer from want of
water. The earliest to bloom is _K. glauca_, followed by _K.
angustifolia_, while later on there is the largest and best-known
species, _K. latifolia_, the Mountain Laurel of the United States, which
has pretty pink flower clusters.
