position over the other occupants of the 
house such as these roof-climbers are at all 
infested with these pests, as a natural con- 
sequence they affect every plant standing 
under them that the insects will live upon, 
entailing an endless amount of labour. 
The position of plants thus trained on the 
roof renders them much more difficult to 
clean than when grown as ordinary pot 
specimens ; it is equally of importance 
that any plants at all affected with these 
insects that are introduced to the house in 
which roof-climbers are grown should 
never be stood in contact with the stems 
of the climbers, for if so placed the pests 
are sure to be communicated to them, the 
worst results of which must follow. Let 
the planting-out be done sufficiently early 
in spring, before any growth has com- 
menced, so that the necessary disentang- 
ling of the roots from the ball of earth 
with a view to spreading them in the new 
soil, can be carried out without injury, 
which would follow if growth in either 
roots or branches had begun. After plant- 
ing give no more water until they have 
commenced to grow; this is necessary to 
keep the soil in a suitable condition. 
During the growing season keep the shoots 
regularly tied up into the place allotted to 
them, and supply the roots with water. 
This Clematis is very appropriate for plant- 
ing at one end of ahouse, and training under 
the ridge. When allowed to hang thinly 
in festoons it has a good effect, and is more 
fitting for being]so grown than things 
which are not naturally calculated for ex- 
tending far. As the soil in which the 
roots are placed gets exhausted, recourse 
must be had to stimulants in the shape 
of copious waterings during the growing 
season with liquid manure and renewal of 
the surface soil in the spring by removing 
an inch or two from the top of the border 
the roots occupy, and replacing it with 
new. When the space is filled which the 
plants are intended to occupy, each year, 
after flowering, the knife should be freely 
used so as to reduce the shoots within 
proper limits, and to allow room for the 
season’s growth. 
Insecrs.—Red spider will, during hot 
weather, sometimes make its appearance 
on this Clematis, and should be guarded 
against by a free use of the syringe. Brown 
scale can be removed by sponging in the 
usual way. If white scale gets upon this, 
or any plant grown overhead on the roof, 
there is no chance for its extirpation except 
cutting the head close in during the winter 
when at rest, and dipping or washing the 
affected stem and remaining shoots with a 
strong solution of insecticide. 
CLERODENDRON. 
There are three very distinct sections of 
Stove Clerodendrons ; one consists of de- 
ciduous twiners, of which C. Balfouri may 
be taken as a representative ; a second is 
C. splendens, which is also a twiner, but 
differs from the last-named section in being 
evergreen and in requiring different treat- 
ment; then comes the third division, which 
consists of evergreen shrubs very distinct, 
and which need treatment different from 
the others. A selection from these sections 
may with advantage find a place amongst 
the best collections of plants; they have 
much to recommend them, inasmuch as 
they grow freely, and succeed with less 
attention than most things, not being im- 
patient of either drought or moisture to 
such an extent as the generality of culti- 
vated plants. The Chinese C. fragrans is 
one of the sweetest-scented flowers grown. 
Another advantage which Clerodendrons 
possess is, they can be flowered in either a 
large or small state, several of them being 
alike suitable for twining round a pillar or 
for draping a rafter. Where room is a con- 
sideration, there is another property pos- 
sessed by the shrubby species that is de- 
serving of attention; it is the way in which 
they may be cut in every autumn, so as to 
occupy little room during the winter; not 
only will they bear this treatment without 
injury, but to keep them in their wonted 
shape it is necessary to so reduce their size 
as to literally head them down. 
As regards cultural requirements, let us 
commence with the shrubby kinds, of 
which we may take C. fallax as a good 
representative. This is a vigorous growing 
shrub, with ample lively green leaves, 
supported on stout petioles 8 or 10 inches 
in length; above these, from the points of 
the current season’s shoots, spring the 
flowers, which are bright scarlet in colour 
and borne in very large stately, erect 
panicles, 10 inches in diameter and a foot 
high. This sort strikes readily from 
cuttings, which can generally be obtained 
about the end of June. When they can 
be got 6 inches long they should be taken 
off with a heel and inserted singly in 3-in. 
pots in half sand and finely-sifted loam ; 
the soil ought to be kept moist and the 
propagating glasses sufficiently close to pre- 
vent the leaves flagging; these, from their 
size and somewhat soft texture, will not 
bear so much air as some kinds of foliage 
until roots are formed. They should be 
in a temperature of 70° at night, and 
allowed 10° more in the daytime during 
bright weather. The cuttings will root in 
a few weeks, when the glasses may be re-
