THE GREEN-HOUSE, HOT-HOUSE, AND STOVE. 
winter, when they will flower beautifully the 
Following summer. Cuttings taken off in 
autumn, and kept in a dry, airy place, where 
frosl is merely excluded, if potted into larger 
pots in spring, will also flower in great perfec- 
tion during summer. The whole family is 
very subject to the attacks of green-fly : when 
that is observed, recourse must be had to the 
fumigation of tobacco, and a slight syringing 
over their tops the day following. The 
shrubby sorts are so hardy that they will stand 
in the open border uninjured during ordinary 
winters, and so also would the herbaceous 
kinds were it not that they suffer from damp. 
"Gardenia. — Most of this genus are hot- 
house plants ; but the two species G-. florida 
and Gr. radicans are best kept in a cool pit 
from the time that they go out of flower till it 
be desirable to make them form flower-buds 
for the succeeding season, when they should 
be shifted into fresh mould, plunged, or rather 
set, on the surface of a pretty strong bottom 
heat, a moist steam heat being kept up in the 
pit, and the lights kept rather closely shut. 
They will by this means show abundance of 
bloom buds and beautiful fresh foliage, and 
when they are just about coming into bloom, if 
removed to the green-house or drawing-room, 
they will continue longer in flower, and per- 
fume the whole apartment with their delightful 
fragrance. They are readily propagated by 
cuttings of the last year's wood, planted in 
rich, light mould, without glasses, in a humid, 
rather warm atmosphere. 
" Alonsoa, and Bouvardia. — Both of 
these strike root freely by cuttings of the young 
wood placed in a slight heat, without cover- 
ing ; their whole culture is of the most simple 
kind ; a soil half peat and half loam suits 
them very well. 
" Lobelia. — This genus has been recently 
divided into several genera : these are included 
under the original name, Lobelia. The small 
species, such as L. eriniodes, &c, seed freely, 
and are increased by cuttings of the young 
shoots. The larger species, such as L. tupa, 
&c, multiply also by seeds, cuttings taken off 
close to the crown of the root, just as they are 
coming up in spring, and also the roots may 
be divided. They all prosper in a rich, light 
soil. 
" Fuchsia.— There is no genus that can be 
more readily increased ; the young shoots root 
freely, and they will grow well in almost any 
kind of soil. 
" Chrysanthemum. — The numerous varie- 
ties of the Chinese species of this family increase 
by cuttings, by dividing the root, and occa- 
sionally by seeds, but these seldom ripen in 
this country. The operation of propagation 
may be commenced almost at any season, and 
in any soil. 
"Plumbago, and Hibiscus. — These two 
genera are usually kept in the stove. P. ca- 
pensis and II. rosa-sinensis, with its varieties, 
are much better in the green-house. They are 
propagated by cuttings of the half-ripened 
wood, planted in sand, and placed in a mild 
heat. A soil composed of good peat and light 
loam is the best for them. 
" Anigozantiios. — This singular and hand- 
some genus is increased by dividing the plant 
near its roots : it grows well in a peaty soil, 
or in peat and loam. 
"Canarina. — This genus is not by any 
means common, notwithstanding its great 
merits. It is increased by dividing the roots, 
and by exciting them in spring, and taking 
the young shoots off when about two inches 
long for cuttings. These are planted in sand, 
and root freely in a moderate heat under a 
glass. A peat and loam soil is sufficient for 
it. The roots should be kept dry during 
winter, like the Dahlia, but kept in the pot. 
" Arctotis and GrAZANiAare both increased 
by separation at the roots, and also by cut- 
tings, which grow freely in a soil composed of 
peat and loam. 
" Erythrina, Crista-Galli, and Lauri- 
folia, are plants of great beauty, lasting long 
in flower. The roots should be kept dormant 
during winter, and excited about the end of 
February, when young cuttings will be ob- 
tained from the numerous shoots that they will 
send up. These, taken off close to the root, 
and planted singly into small pots filled with 
sand and placed in a mild heat, will root freely, 
and if forwarded in the hot-bed or stove will 
flower the same season. But the best flowers 
will be obtained from the old plants, which can 
scarcely be put into too large a pot, and placed 
in the green-house. So hardy are both species, 
that they will stand out of doors planted in 
the ground, with a very slight protection. A 
rich soil should be given to them, as that will 
add much to their size, and to the beauty of 
the spikes of flowers. 
" Brugmansia. — This genus is readily in- 
creased by cuttings taken off when quite young 
from near the root. If planted in any light, 
rich soil, they will grow rapidly. They re- 
quire repeated shifting, because the larger the 
plant can be grown before flowering the better. 
" Clerodendron. — Of this genus the spe- 
cies C fragrans is a beautiful and fragrant 
green-house plant, although generally kept in 
the stove. It is readily propagated by cuttings 
of the young wood, placed in a warm situation. 
A light, rich soil is requisite to have this plant 
in perfection. 
" Humea is increased by seeds sown early 
in spring, and treated like any pot-cultivated 
annual. It often flowers the first season, but 
always the next.
