out, as much of the old soil may be re- 
moved as can be gotaway without injuring 
the roots. During this summer the plants 
will attain a size that will enable them to 
produce flowers as abundantly as may be ex- 
pected, however long they are grown ; with 
treatment such as advised they will usually 
last for years, but being essentially what 
may be termed plants of small growth, 
they have a better appearance, and are 
more useful when cultivated in numbers of 
medium size than when grown larger. 
Consequently it is advisable to propagate 
a sufficient quantity of young ones each 
year to take the place of those that get less 
shapely and are not so well furnished. 
This Impatiens is an excellent subject for 
growing in small or medium-sized wire 
baskets suspended over the paths, and in 
no position is it seen to better advantage 
when in flower ; but when so used, instead 
of being trained upright, the shoots should 
be tied in a horizontal position over the 
edge of the basket. For this purpose it is 
also better to use three or four of the 
young-struck cuttings together. It is like- 
wise better to keep them in pots, plunging 
these in the baskets, filling up with sphag- 
num, in which a few pieces of Lycopodium 
are planted in the spring ; the appearance 
of the baskets is thus much improved, and 
the general effect when the plants are in 
bloom heightened. Their treatment in 
other respects when in baskets requires to 
be in no way different from that which is 
advised for pot culture. When they flower 
sufficiently early in the summer months 
before the cool autumn weather sets in, 
they may be put for a few weeks in a con- 
servatory, but not exposed during the time 
to currents of cold air. 
There are several other species, some of 
which attain a larger size than I. Jerdoniz, 
they strike easily and are grown on with 
little difficulty ; cuttings put in early in 
spring, and moved on as they require more 
pot-room, make handsome blooming plants 
the same season, keeping on through most 
of the summer andautumn. For ordinary 
purposes it will be found better to propa- 
gate stock of these each spring. 
I. flaccida. A dwarf bushy plant, that 
bears bright purple flowers. From Ceylon. 
I. flaccida alba. A white-flowered form 
of the preceding. 
I. repens. A dwarf species, with yellow 
flowers. Ceylon. ; 
I. Sultant. A new species, with a dense 
bushy habit ; it attains a considerable size, 
and is a profuse bloomer, keeping on 
through much of the autumn and winter, 
as well as the summer season ; the flowers 
are rose-coloured. It comes from Africa. 
InsEcts.—We have never seen these Im- 
patiens attacked by any of the usual stove 
pests, except greenfly, for the destruction 
of which fumigate repeatedly, but not too 
severely. 
INDIGOFERA. 
; 
The Indigoferas are a large genus of 
plants found in various parts of the world, 
the East Indies, West Indian Islands, Cape 
of Good Hope, New Holland, China, &e. 
Few of the species are worth a place, and 
even the most favourite greenhouse kind, 
I. decora, is now seldom seen. They thrive 
under treatment such as recommended for 
Cassia Corymbosa, which see. 
The following two species are among the 
best :— 
I. australis. An evergreen shrub_ that 
bears pink flowers. From New South 
Wales. 
I. decora. An evergreen shrub from 
China, with pink flowers, produced in 
summer. 
IPOMGA. 
One of the handsomest of Ipomceas is I. 
Horsfallize, a species of smaller growth 
than most of the genus; it is a twiner, 
and comes from the hot, moist regions of 
Africa or East India, consequently there is 
no use attempting its cultivation except 
where there is enough heat at command to 
keep it in a,healthy state. When first it 
became generally known it was to be met 
with in most places where there was 
sufficient heat, but now it is rarely seen, 
and still seldomer in good condition, 
although it is by no means difficult to 
cultivate when once it gets established. 
It is not an easy subject to strike, being 
one of the plants that used to be held up 
by experts to young aspirants in the pro- 
pagating department as a test of their 
abilities. Yet, with a knowledge of the 
right age and condition that the wood 
should have attained when made into 
cuttings, roots may be produced, but still 
much more time is required than with 
most other plants. A knowledge of the 
exact state the wood should be in when 
made into cuttings is difficult to convey 
in writing, and can only be acquired by 
practice and observation. So far as our 
own practice goes we have been able to 
succeed best when the cuttings were made 
from the preceding year’s shoots imme- 
diately after flowering about the end of 
February ; if these are inserted singly in 
small pots half filled with a mixture of 
peat and silver sand, the remainder all
