ia is a twiggy bush,
with bright yellow flowers, like those of a single Rose, and expand
quickly in spring. The major form of the double Kerria is much better
than the ordinary one; they can be potted in autumn or grown permanently
in pots. After the flowering season is over the double variety can be
spurred back hard to prevent a tall weakly growth.

LABURNUM.--This has long been used for the greenhouse, and very
effective it is when well flowered. It is as a rule most successful when
in large pots, in the shape of a standard. Prune back moderately after
flowering.

LONICERA (Honeysuckle).--As _L. fragrantissima_ flowers naturally out of
doors soon after Christmas when the weather is mild, it is evident that
no forcing is needed to obtain it at that season, and in a cool
greenhouse the little white flowers are remarkable for their delicious
perfume. As spring advances the early Dutch may be flowered under glass,
while the scarlet Honeysuckle (_L. sempervirens minor_) is a delightful
greenhouse plant, not used so much as it deserves to be for rafters and
similar purposes in the greenhouse.

LOROPETALUM CHINENSE.--This Chinese shrub, with its long, pure white,
strap-shaped petals, bears much resemblance to the Chionanthus, and is
quite as desirable for flowering in pots. It may be either lifted in the
autumn or grown altogether in pots.

MAGNOLIA.--The Magnolias can be grown under glass. If allowed to come
gradually into bloom in a greenhouse the large flowers will open freely.
As a rule they transplant badly, and for that reason, at least the
choicer ones, are kept in pots for convenience in removal. From this it
will be understood that as a rule it is more satisfactory to keep them
permanently in pots than to lift them in the autumn. _M. purpurea_ can
be grown more easily than any of the others in this form. When grown in
pots for the greenhouse, if they get too large for that structure they
may be planted permanently out of doors and their place taken by smaller
plants. Of those particularly valuable for this treatment are the little
_M. stellata_, a charming shrub; _M. Lenne_, which has massive
chalice-like flowers, rosy-purple outside; _M. conspicua_, _M.
soulangeana_, and _M. purpurea_ among the early Magnolias; and of those
that flower later the Japanese _M. parviflora_ and _M. Watsoni_ do well
in pots.

OLEARIA.--The best known of the Daisy trees of New Zealand is _O.
Haastii_, which flowers freely in Augus
