THE GARDENING WORLD. 
June 2, 1894. 
upon the Laburnum, when it may be planted on the 
grass or in some prominent position. A round um¬ 
brella head, inclined to droop in the manner of a 
Weeping Willow, is then formed, and is both grace¬ 
ful and pretty when in bloom. The purple flowers 
are, however, quite as acceptable when seen amongst 
the stones and boulders of a rockery. 
L.4BURNUM Adami. —No tree is more sportive than 
this graft hybrid. The tree grows rather slowly so 
long as it remains true to character, but when the 
shoots that revert to Laburnum vulgare are allowed 
to have free scope, they soon overmaster the hybrid, 
and in the course of a few years yellow flowers pre¬ 
dominate, or they even monopolise the whole tree to 
the exclusion of the coppery-purple of this hybrid. 
Those who value the flowers of the latter should 
keep the growths bearing the yellow flowers in 
check. 
The Scarlet Thorn. —At present it is difiicult to 
say whether the Scarlet or white Thorn is the more 
conspicuous as seen in parks, pleasure grounds and 
shrubberies. The Double Scarlet Thorn is variously 
known as Crataegus Oxyacantha rosea-superba plena 
or C. O. punicea plena. The dark red petals are pale 
beneath, so that the flowers lack a little of their 
intensity till fully expanded. The abundant sun¬ 
shine last year must doubtless be held accountable 
to some extent for the profusion of bloom, but the 
Thorns hardly ever fail to make a respectable 
appearance, whatever the previous season may have 
been. 
The Burnet Rose. —No one would think of 
planting either the single or double forms of Rosa 
spinosissima in beds amongst the hybrid perpetuals, 
yet there are places in the garden for which it would 
prove suitable and even beautify them. The species 
is valuable for its dwarf habit, small and finely 
pinnate leaves, and its relatively large, creamy-white 
and fragrant flowers. It is the first of our native 
Roses to bloom, and with exception of the Banksian 
and China Roses, precedes most of the cultivated 
ones. The margin of the shrubbery, the upper 
ledges of the rockery, and beds upon the grass form 
suitable places for this interesting subject. 
Pyrus Smithii. —A specimen of Smith’s Medlar, 
about 15 ft. or 20 ft. high, forms a beautiful object 
when in bloom. In habit the tree is not unlike a 
Hawthorn, but the spray is not so fine; the branches 
in fact are stouter, and the pure white flowers, 
individually, are much larger. In this respect the 
tree shows its distinctness, and merits a place even 
midst the wealth of trees that are flowering at the 
present time. It is best known under the name of 
Mespilus Smithii, and M. grandiflora is another 
synonym. 
Clematis alpina. —Although an old inhabitant of 
gardens this beautiful climber is very much ignored. 
We have evidence of this in the fact that it was 
brought before the public some time ago, grown and 
flowered in a pot, when it was honoured with a 
Certificate. The flowers consist of four sky-blue 
sepals, with ten to twelve small organs, which are 
sometimes termed petals. Like all other species of 
Clematis the coloured sepals are the most orna¬ 
mental part of it, and are very acceptable when few 
of the others are yet in bloom. It does best on a 
wall. 
Clematis Montana. —Annually with the return of 
May, as far as Britain is concerned, anyone going 
the round of the country cannot fail to be charmed 
with a tall climber covering the walls of various 
gardens, and even the walls of cottages in many 
localities. The stems are only just coming into 
leaf when the stems get clothed with a wealth of 
white blossom. The flowers individually are 
moderate in size, with four white petals, but they 
make amends by their enormous number. The 
climber is amenable to various kinds of treatment, 
and, if so desired, the principal stems alone may be 
retained, spur pruning them in winter, and a great 
profusion of flowers will be developed nothwith- 
standing. 
Ribes speciosu.m. —The ornamental species of 
Ribes are generally spineless, but that under notice 
is an exception, and when not in leaf reminds one of a 
Gooseberry, but is even more spiny, and the flowers 
resemble those of a small wild Fuchsia. For that 
reason it has been termed the Fuchsia-flowered 
Gooseberry. Being a native of California, it is 
occasionally liable to get a little injury from frost, but 
when grown against a wall there is little danger. 
The pendant flowers are crimson with long project¬ 
ing stamens. The plant may be propagated from 
cuttings or layers. 
Aesculus glabra. —The red flowered Horse 
Chestnut is now gay everywhere, and its bold and 
striking efiect when seen in good condition should 
encourage its planting in parks and pleasure grounds 
where its beauty is nowhere better shown off than 
by contrast with the common white one. The 
flowers are not so dark in colour as the Red Buck¬ 
eye (Ae. pavia), but they are much larger and far 
more effective.

DEUTZIA GRACILIS. 
' What a useful flowering shrub this is. It readily 
adapts itself to all kinds of treatment, but I think 
never looks so pretty as when well grown in pots, 
and it can be easily had in bloom at Christmas 
without much trouble. I should like to lay down a 
rule for the treatment of old plants so as to keep 
them shapely and in good health. When the bloom¬ 
ing period is over repot the plants and thin out the 
weak shoots. Keep them well supplied with water 
through the summer, and not leave them to be 
starved as many do. If they cannot be constantly 
attended to, if in pots it is much better to select a 
piece of good land which has been well worked and 
plant them out. String a line and draw out a trench 
to the depth of Sin. or 9 in., then turn out the plants, 
shake out the old soil, and trim off the old roots so 
as to reduce the ball to smaller dimensions. This 
done plant them 9 in. apart, with the rows 12 in. 
asunder. For the final stroke take a knife or the 
pruning shears and cut off the old tops to the ground. 
No one need 456 afraid of doing this, for instead of 
plants of a stunted and unshapely appearance they 
will get one with all clean, strong, new wood, which 
if occasionally encouraged by the application of good 
watering in dry weather will lift grandly in the 
autumn and make fine stuff for pot work.— J. G.

IVIES AT CHISWICK. 
[Concluded from page 612.) 
Leaves five angled. 
This type is represented by the common wild Ivy 
in the woods and hedges, and on the rocks of this 
country. The Irish Ivy is also typical, but on a 
larger scale. In the creeping or climbing stage the 
leaves are five-angled; but when the plants attain 
the flowering stage, erect or ascending shoots, bear¬ 
ing ovate, undivided leaves, are developed. 
Canariensis. —Of the cultivated Ivies this is the 
commonest of all, used for covering walls and 
buildings throughout Britain, according to our 
experience. The leaves are very broad, five-angled, 
and when newly developed are of the richest, dark 
green hue of any we have noticed, with exception, of 
course, of the varieties belonging to it. Ultimately 
they are of a dark olive green with pale grey veins. 
It is the Irish Ivy, and is also known in nurseries 
under the names of Arborescens and Grandifolia, 
Canariensis maculata (here named Canariensis 
latifolia maculata) has the young leaves washed 
with yellow and the old ones washed and splashed 
with gray. Canariensis variegata (here named 
Hibernica variegata) is irregularly splashed or 
blotched with yellow on the young leaves and with 
cream colour on the old leaves. It is perfectly 
distinct from Canariensis maculata, on account of 
the fewer and larger blotches on the leaves. The 
intensity of the green hue of the young leaves is 
common to all the three forms : and the same may 
be said of their size. 
Marmorata.— The leaves of this variety are much 
smaller than those of Canariensis, marbled with 
cream when young and with gray when fully 
matured. Marmorata elegaotissima seems a sub- 
variety, with smaller leaves, and more distinctly 
marbled with gray as a rule in the final stage. 
Maculata minor and Discolor do not seem to possess 
any tangible marks of distinction to separate them 
from Marmorata. 
Pallida. —This has also the small leaves of 
Marmorata, but the leaves are green, some of them 
being blotched with bright yellow, fading to a 
creamy hue in winter. Not unfrequently some of 
the shoots develop leaves that are wholly yellow. 
The variegation, however, is so inconstant and 
irregular that we cannot admire the variety at all. 
It is closely related to Canariensis, as is Marmorata, 
the chief difference being their smaller size. All the 
three varieties, with their subvarieties, therefore form 
a very natural group. 
Chrysophylla. —The moderate sized, three to 
five angled leavms of this variety are golden-yellow, 
netted with green when young, but ultimately deep 
green, variously netted and marked. The summer 
foliage is the best, and at that time it may be 
regarded as a beautiful Ivy. 
Lucida. —There is a plant under the name of 
Lucida poetica, but the reason for the additional 
name of poetica is not very apparent. The leaves 
are large, deltoid, three to five angled, and of a rich 
shining green, ultimately very dark green. Some¬ 
times there are several large teeth along each side. 
We have previously mentioned the fact that there is 
a plant under the simple name of Lucida. but it does 
not agree with the present plant in any way, and we 
suspect it to be the young state of Lobata major, as 
stated under the description of that variety. 
Tree Ivies. 
Arborescens aurea. —This is a golden variety of 
the flowering or so-called tree form of the Ivy. 
When grown against a wall the leaves are variable, 
some of them are three-angled on the climbing 
shoots and the rest ovate. The latter more especially 
are bright yellow when newly developed, and 
ultimately grayish-green or variously washed with 
dull creamy-yellow. The young shoots that project 
away from the wall, that is the flowering shoots, 
constitute the type of this variety. When grown as 
a bush the creeping shoots that occasionally arise 
should bs removed. There are plants here under 
the names of Arborea aurea. Gold Clouded, and 
Spectabilis aurea. Two plants under the latter 
name are erroneously so termed, because the name 
is applied to a very distinct and rarer kind. 
Arborescens argentea. —The stems of this 
variety are more slender and the leaves much 
smaller than in the case of Arborescens aurea. The 
leaves are triangular or ovate, and very often con¬ 
cave like a bicolor Pelargonium, with a broad pale 
yellow margin ultimately silvery. It has many 
running stems, and is therefore suitable for covering 
walls or trees. There are plants under the names of 
Sulphurea and Sublutea, and it would seem that 
Luteola is considered the proper name for it by some 
authorities. 
Arborescens mapginata.— The leaves of this 
variety are also small, ovate, with a pale greenish- 
yellow margin, ultimately becoming silvery, but 
irregular in outline. They do not, however, become 
concave like those of Arborescens argentea. 
Broad-leaved Silver.— Here the leaves are of 
medium size, ovate, rather infolded at the sides, 
bright green when they expand, with a creamy edge, 
but when fully developed they are grayish-green with 
a silver edge. The plant loses all its old leaves by 
the time the young ones are produced. 
Japonic A variegata. —In most respects this 
agrees in the form and colour of the leaves as well 
as in its decidedly arborescent habit with Broad¬ 
leaved Silver, but is said to be of more robust consti¬ 
tution, and freer growth. 
Algeriensis Variegata. —This has already been 
mentioned as a variety of Algeriensis, because of the 
name, but it is decidedly of arborescent habit. 
Rhombea. —The leaves of this variety are large, 
and vary from rhomboid to ovate, are incurved at 
the sides, and dark shining green with a very 
narrow, creamy edge, ultimately becoming dull, 
grayish-green with a silvery edge. The plant is 
grown under the name of Rhomboidea obovata varie¬ 
gata, but seems to have nothing in common wdth the 
ordinary green form under that name. It would, 
seem to have more affinity with Algeriensis varie¬ 
gata, but the leaves are shorter and proportionately 
broader. 
Cruppsii. —The habit of this sort is less distinctly 
arborescent than either of the foregoing, but the 
leaves vary from triangular to rhomboid, and are 
light green with a creamy margin changing to silver, 
and washed with gray all over. They are also very 
moderate in size. 
OvATA.—The leaves of this sort are moderate in 
size, cordate or roundly heart-shaped, and bright 
green when young, but ultimately deep green with 
slender gray veins. 
Glymmii. —This sort is more truly arborescent 
than either of the two previous ones, and does not 
readily take to w-all culture. It should be grown as 
a bush. The leaves are of medium size, broad, 
rhomboid, sometimes slightly three-lobed, convex, 
bright shining green, ultimately assuming a very 
dark, glossy green. The plant is very suitable for pot 
culture.
