nd thinning wiry and exhausted growths; but remove seed
pods directly the flowers are over, as these are a drain upon the
plant's strength.

BERBERIS.--Few Berberises are of much account for greenhouse decoration,
the best being the orange-flowered _B. Darwinii_ and the rich yellow _B.
stenophylla_. They will not flower well if forced hard, but in a cool
house, with very little heat, they are very charming. A successful
grower of shrubs under glass writes: "I knew of some bushes of _B.
stenophylla_ that had been treated in this way for five years, and
little trouble was taken with them, yet they were so beautiful as to be
much admired every year. After flowering, the weakly growths were cut
out and the pots plunged in the open ground. Manure water was
occasionally given, and with this treatment they did well."

CARPENTERIA CALIFORNICA.--This evergreen shrub, even in the south of
England, is all the better for slight protection, and it is delightful
in the almost cold house, the white flowers, reminding one of those of
the Japanese anemone, appearing about May. It is a very beautiful shrub.

CARYOPTERIS MASTACANTHUS.--This Chinese shrub will bloom freely in light
and warm soils, bearing lavender blue flowers in profusion during the
autumn; indeed, so late that when cold and wet weather occurs they often
fail to expand at all. This difficulty is overcome when the plants are
grown in pots and taken into the greenhouse for the flowers to open; it
is then very pretty and much liked. After flowering, the shoots
generally die back almost to the ground, but break up with renewed
vigour in spring.

CEANOTHUS.--Some of the early-flowering Ceanothuses are very valuable;
they may be grown in pots, and their flowers are of pleasing blue
colouring, which is unusual and therefore welcome. Among the best for
this purpose are _C. dentatus_, _C. papillosus_, and _C. veitchianus_.
Ceanothuses do not transplant very well, and if intended for flowering
in pots should be lifted in the autumn, potted carefully, and wintered
in a cool house. They may be kept altogether in pots, giving them much
the same attention during summer as _Berberis stenophylla_.

CERCIS SILIQUASTRUM.--This is the Judas tree, and as many know, while
the leaves are still absent the stems bear clusters of rosy-purple
flowers. It may be lifted and potted in the autumn or kept altogether in
pots, but on no account indulge in hard forcing, as it resents this
treatment.
