THE GARDENING WORLD 
July 22, 1905 
scarcely help you in the matter. The question is 
one which really belongs to entomology rather 
than gardening, and if there is a museum or De¬ 
partment of Agriculture in South Africa, that 
would be the best place to settle all questions 
concerning insects, injurious or otherwise, native 
to that part of the world. 
Autumn Flowering Colcliicums. 
Will you kindly give me through the columns of 
The Gardening World the best three autumn¬ 
flowering Colcliicums, not very expensive ones, 
and good foliage a consideration ; also when to 
plant ? (Murr aythwaite. ) 
It is easier to name good autumn-flowering 
Colcliicums than to give you all the qualities 
which you require combined in one plant. The 
three best species would be Colchicum autumnale, 
C. variegatum and C. speciosum. These are 
selected for the reason that they give a succes¬ 
sion. All of them have good foliage, but the 
leaves are not produced until spring. If you re¬ 
quire species producing their leaves and flowers 
together, then you must be content with flowers 
of smaller size and blooming from mid-winter 
till spring more or less rather than in autumn. 
Amongst this lot we should name C. libanoticum, 
C. hydrophilum, and C. crociflorum. Several 
others of this character could be named which 
produce their flowers and leaves together, but 
owing to the time of the year at which they 
bloom they must be kept under glass if satisfaction 
is expected from them in the way of flowers in your 
northern latitude. The plants, however, are 
much smaller in every respect than the autumn 
flowering ones which we named, and consequently 
you might object to them on this score. On the 
other hand, there is no reason why you should 
not get the half-dozen which we have named, as 
most if not all of them are to be obtained cheaply 
in this country at the present time. C. crociflorum 
is really a very handsome one, being striped like 
a Crocus, and is the last to come into bloom of 
those we mention. The autumn-flowering ones 
should be planted out in August, and the three 
others potted not later than October. 
Violas and Green Fly. 
For some time past my Violas have been making 
no progress whatever, owing, I suppose, to them 
being infested with green fly- What remedy can 
you suggest that would kill the pest without 
injuring the plants? (A. J. Bentley.) 
A very simple and easy method of checking the 
multiplication of green fly upon Violas is to 
syringe them overhead, so as to slightly damp 
them, and then dust the growing crowns with 
tobacco powder. This may be rather a slow 
process unless you have something that will dis¬ 
tribute the powder rapidly. There can be no 
question, however, that it is a very effectual 
method of stopping the depredations of green fly 
on Violas. The damping with water is merely to 
hold the tobacco powder until it has thoroughly 
effected its mission. There can be no doubt also 
that the slow growth made by the plants is en¬ 
tirely due to this insidious enemy. 
Best Evergreen Cotoneasters. 
Will you kindly give me through the columns of 
The Gardening World the best evergreen 
Cotoneasters and other wall-coverers—other than 
Ivies, Garryas and Escallonias—especially please 
regarding the first-named. (Mtjrraythwaite.) 
In our opinion and experience, the best ever¬ 
green Cotoneasters for wall coverings are C. 
microphylla, C. Simonsii, _ C. rotundifolia, C. 
buxifolia, and C. horizontalis. All of the above 
are evergreen, with the exception perhaps of C. 
Simonsii, which loses its leaves in smoky towns, 
but should behave differently with you. We could 
mention several other beautiful evergreen species, 
but we fear they would be less satisfactory as 
wall coverings than those we have given. C. 
microphylla. gives the most dense evergreen cover¬ 
ing of any that we have seen employed for this 
purpose. 'There is a new one of great promise, 
which we think will yet prove to be a very 
handsome subject, but at present it is scarce and 
dear. We refer to C. angustifolia, figured in The 
Gardening World for December 24th, 1904, pp. 
1047 and 1048. The Fiery Thorn (Crataegus 
Bvracantha) is very similar to a Cotoneaster, and 
is also evergreen. It makes a splendid wall 
covering, even in the far North. There are 
several species of Jasminum which are usually 
regarded as evergreen on account of the colour of 
the stems rather than the foliage, and this would 
include J. nudiflorum, J. officinale and J. revolu- 
tum, all of which are hardy in Britain. You 
may well try- some of the species of Elaeagnus, 
such as E. glabra, E. g. foliis variegatis, E. 
pungens. variegatus, and its variety E. p. aureo- 
maculatus, which prove very hardy in the South, 
and we think would answer your purpose and 
prove hardy in your district. 'Several others we 
could name, but as you have the best of them it 
would be well to try those which have been named 
before attempting the evergreen species of 
Ceanothus, Choisya ternata, Magnolia grandiflora, 
etc. 
Rapid growing Roses for Walls. 
Will you kindly give me through the columns 
of The Gardening World advice on rapid-grow¬ 
ing Roses to cover walls, continuous flowerers and 
bearing leaves long. Give the ten best for South 
of Scotland, mild but windy. (Murkaythwaite.) 
In order to combine all the characters that you 
require it would be necessary to get qualities 
belonging to different groups of Roses. For in¬ 
stance, if you require the leaves to hang over the 
winter it would be necessary to select evergreen 
varieties, which, as a rule, cannot be described as 
perpetual bloomers. For instance some good ever¬ 
green varieties are Flora, Dundee Rambler, and 
Felicite Perpetue, but we are afraid they would 
not give you continuous blooming like those be¬ 
longing to the Tea and Hybrid Tea sections. 
Amongst Teas, we should recommend Gloire de 
Dijon, Mine. Berard and Bouquet d’Or. Excellent 
Hybrid Teas for the same purpose are Longworth 
Rambler, Reine Marie Henriette, Monsieur Desir 
and Reine Olga de Wurtembourg. Good Noisette 
Roses for walls are Reve d’Or, William Allan 
Richardson and Aimee Vibert. Mme. Alfred 
Carriere is a good hybrid Noisette. The above 
exceeds your number, and if any are to be omitted 
we leave it to you, as you may possibly have some 
of those already which we have named. In any 
case, all of them are first-class Roses for the pur¬ 
pose named. We hesitated to recommend 
Marechal Niel, as it does not succeed equally in 
every garden out of doors. 
American Blight on Apples. 
Last year some young Apple trees got badly 
blighted with American Blight, and now it is 
appearing again. Can you say what would effec¬ 
tually check it? (A. M. E.) 
At this season of the year, when the trees are 
in leaf and fruit, it would be unsafe to employ 
some of the washes that you could utilise with 
good effect in winter. At. present, however, you 
will have to use a half-worn painter’s brush, and 
dip it in some or other insecticide that will kill 
the American Blight by direct contact with the 
fly in the affected spots. Methylated spirits are 
very useful for this purpose, or you could use a 
solution of ammonia. The brush' may simply be 
dipped into either of these and the blighted por¬ 
tions well scrubbed with the brush, being careful 
both of the fruit and foliage not to touch them 
with these insecticides. It would no doubt save 
you a deal of trouble in summer if you would take 
the trouble to remove the soil around the base 
of the tree and to place in the hole a layer of 
lime or soot, as the aphis which produces what 
is termed American Blight often lives there in 
numbers upon the roots during winter, and then 
comes out in summer to attack the stems and 
shoots of the trees. Winter time would also be 
suitable for removing all the rough portions 
around the diseased spots, so as to let you get 
at any insects or eggs that may be concealed 
there. At that time you could safely use paraffin 
or paraffin emulsion to scrub the diseased spots.

International Show at Edinburgh.— The 
Council of the Royal Caledonian Horticultural 
Society met on the 12tli inst., when arrange¬ 
ments were further matured for this forth¬ 
coming event on 13th to 15th September. 
Already a considerable number of applications 
for space for non-competitive exhibits have 
been received. The last date for receiving 
these is 27th inst. On the representation of 
prospective exhibitors, the Council have modi¬ 
fied the rule as to staging exhibits by 11 p.m., 
and have now resolved that, with the excep¬ 
tion of a few classes of exhibits which are 
specially mentioned in the schedule, all ex- 
1 ubits must be in the Waverley Market by mid¬ 
night on 12th September, and all staging must 
be completed by 3 a.m. 
Bill for the Sale of Poisons. —In the 
House of Commons, on the 13th inst., Mr. 
Alexander Cross, M.P., asked the President of 
the Board of Agriculture when lie proposes to 
introduce his Bill dealing with the sale of 
substances used extensively and in large quan¬ 
tity in horticulture and agriculture, but which 
are technically included as poisons under the 
schedules of the Pharmacy Act, in view of the 
efforts made to monopolise the trade in sucli 
articles by retail druggists, to the injury of 
these industries of f arming and gardening, and 
in reply he received the following answer: — 
“ The Bill in question falls within the pro¬ 
vince of. the Privy Council rather than my 
own, but I am in communication with my 
noble friend the Lord President as to the ad¬ 
visability of its introduction at no distant 
date, and, further, that the Bill is in a state 
cl preparedness.”
