Greenhouse and Stove Plants. 
MANDEVILLA, 
bloom nicely the following year. The 
flowers are of a brown colour. This 
Magnolia forms a large bush, and is best 
suited to a large cool house, where it will 
go on for years if given enough root-room, 
with the assistance of manure-water. 
Insects.—Syringe freely to keep down 
red spider. Should aphides become trouble- 
some fumigate with tobacco. 
MANDEVILLA SUAVEOLENS. 
In this we have one of the most desirable 
plants for decorating the roof of a cool 
conservatory or greenhouse. It is a climber 
of moderate growth, bearing pure white 
trumpet-shaped flowers, very handsome, 
and highly fragrant. Its flowers are pro- 
duced freely through the summer and 
autumn ; it is very distinct in appearance, 
and is in every way a much more suitable 
plant for a roof-climber than numbers 
that are more generally grown. In addition 
to the properties already mentioned it has 
the important advantage over many con- 
servatory climbers of not being over- 
rampant in habit. The deciduous habit of 
the Mandevilla prevents any injury being 
done byshading through the winter months 
to plants grown under it, when all the 
light that can be obtained is required. In 
no way is the plant seen better than when 
planted in the centre of one end of a span- 
roofed house, and trained up along under 
the ridge, from which its blooming shoots 
will hang in festoons; a very few flowers 
will scent a large house. It is not an over 
strong rooted subject, and will grow more 
freely if planted in peat than loam, although 
it will do in the latter. It is not suitable 
for growing as a pot specimen, consequently 
it is better to treat only upon its culture 
as a climber. It comes from Buenos 
Ayres. Like other subjects of not over- 
strong habit, if turned out when small into 
a considerable body of soil in an open 
border, the chances are against its doing 
well. It can be raised from seeds or from 
cuttings, the last-named method will be 
more within the reach of most cultivators. 
Cuttings such as required will be found in 
the right condition about May, in the 
shape of young shoots that have been made 
by established plants that have been cut in 
and have broken fresh growth ; when these 
are 4 or 5 inches long take them off with a 
heel and put singly in small pots half 
filled with sand and peat, the top all sand. 
Kept moist, shaded, and covered with a 
propagating glass, in an intermediate tem- 
perature they will soon root, after which 
dispense with the glass, and encourage 
growth by continuing a growing tempera- 
ture and syringing daily overhead. By 
the middle of July the young plants should 
be ready for moving into 3 or 4 inch pots, 
using soil made moderately fine, with 
some sand in it ; keep close until the roots 
begin to move freely, after which admit 
more air. A stick should be placed to 
each plant, to which the shoots should be 
trained ; give alittle shade all through the 
summer when the sun is powerful, towards 
autumn admit more air, keep the atmo- 
sphere drier, and leave off syringing. 
Keep at a greenhouse temperature through 
the winter, and about the beginning of 
April move into 6-inch pots, treating 
subsequently during the summer as in the 
last, giving to each plant a tall stick, to 
which train the shoots. Winter as before, 
and about the beginning of April if well- 
rooted give a 3-inch shift, use good fibrous 
peat, to which add one-sixth of sand, drain 
the pots well and pot firm, inserting just 
inside the rim three or four 4-feet sticks, 
round which through the season keep the 
shoots regularly trained. While young 
they are tender, and if allowed to get 
entwined in each other they will be difficult 
to separate, and are almost certain to 
receive injury in the operation. When 
potted, place them in a house or pit where 
they can be kept moderately close for a 
short time; a temperature of 50° in the 
night, with a rise in the day according to 
the state of the weather, will answer for 
them. Do not give much air for a few 
weeks until the roots have begun to enter 
the new soil, only so far as requisite to 
keep the temperature from rising too high. 
When they show signs of growing freely, 
give plenty of air in good time in the 
morning and during the day, closing 
sufficiently soon to raise the temperature 
considerably by sun-heat. The plants will 
now need more water at the roots, and as 
the season advances it will be necessary to 
use the syringe more freely than requisite 
with many things, as it is subject to red 
spider. To keep this pest in check the 
whole of the leaves, on both the upper and 
under surface, should be reached by the 
water. Continue this treatment through 
the summer, shading a little when the sun 
is very bright, and moistening the atmo- 
sphere by sprinkling the paths and under 
the stages. Keep on treating in this way 
until the beginning of September, when 
they should be no longer syringed or 
shaded ; give abundance of air so as to 
discourage further growth and to ripen up 
the wood. 
Keep them through the winter at an 
ordinary greenhouse temperature of 35° or 
40° in the night until the end of March,
