Hear white as Arnold's Virgin Queen; next to that 
pure colour, one witli a deep purple, such as Alonzo, 
adds greatly to tlie beauty of both. Those examples 
will bo sufficient to guide the amatem' in arranging the 
colours of his blooms to the greatest advantage. 
Mode of Conoeijance .—The best conveyance for large 
plants is a wide, close-covered spring van or vans, with 
four wheels each. In this place a layer nine inches | 
thick of coal-ashcs, just moist enough not to be dusty, 
and not so wet as to cling to or dirty the pots. Set i 
each plant close to the hottom of the van, and do not 
let them touch each other. Some place a long strand 
of mat round each plant, drawing the branches closer 
together, in order to get more plants into the van ; but 
this is very injudicious, as the blooms then rub against 
each other, and are disfigured thereby. It is better and 
safer, and more economical in the end, to have, rather 
than crowd them, an extra van if one will not hold the 
collection. As each plant is placed in the van, let the 
packer press the ashes firmly to the pot, to prevent it | 
slipping out of its place in going up or coming down a 
hill. The driver should be a careful, attentive man, and 
keep his eyes constantly upon the road during the 
journey. He should, if possible, avoid every loose stone 
or deep hole, in order to keep the plants steady, and 
shake the blooms as little as possible; a constant atten¬ 
tion to this point will save the plants many a jolt, and 
bring them safely to their destination. The Pelar¬ 
gonium, with moderate care, may be conveyed safely a 
great distance ; in proof of which T need only mention 
that the Messi’s. Veitch, of Exeter, have sent them all 
the way from that place to London, brought them safe 
and fresh, and taken a prize with their collection. 
I have now gone through the whole course of Pelar¬ 
gonium culture as an exhibition plant. I shall, in my 
next paper on this subject, give, as proposed at page 
3(i5, a list of the best varieties for 1853.

PRESERVATIVE WALLS.

LIST OF SUITABLE PLANTS. 
PiTTOSPORUM Tobiba (Tobira Pittosporum). — An 
evergreen, slow-growing, handsomc-foliaged shrub, with 
stalkless clusters of pure white sweet-scented llowers. 
PiTTospoBUM uNnuLATOM (Wavy-leaved Pittosporum). 
— The leaves of this species are longer and thinner 
than the preceding, and besides this, they are undulated, 
that is, parts of the leaves rise up, and the other parts 
sink down, giving it the ajipearance of the waves of the 
sea; hence its specific name. The flowers are produced 
in loose panicles, and are white and green in colour, 
j Jjike the P. tohira, they are sweet-scented. 
I These two species are both evergreen and hardy 
j enough to bear our winters against a cold wall, if 
I sheltered with a mat in severe weather. 
I PuNicA GBANATUM (Tho Pomegranate). — This well- 
known shrub is not hardy, excepting against a wall. 
The flowers are large, and of a licli scarlet-colour, fl'hey 
are produced on small twigs; hence, in ])runing them, 
; a large quantity of these twigs should bo left on the 
' branches. The flower-buds are very beautiful, even 
' before the flowers expand. There arc several varieties, 
all distinguished by variations in colour; but the 
original species is by far the finest; tho double red being 
I an exception—it is still more beautiful. In tho North, 
j this lino tree requires protection to bloom it well; yet 
' it will not bloom well in a greenhouse, probably because 
I it does not obtain there a sufficient amount of rest 
' during winter. The best bloomed plant I ever saw was 
j)lanted against a west wall, in a stable-yard that was 
paved close up to the stem; the soil was thin and poor. 
but very dry, conditions that most likely were favour¬ 
able to tho production of these beautiful flowers. I 
never saw it fruit in this country ; but I have no doubt 
it would produce its beautiful fruit in a preservatory. 
Rapiiiolepis. — A genus of shrubs, with evergreen 
foliage and handsome flowers. All from China, and 
hardy enough to bear our winters on a glass-covered wall, 
without heat. They are very little known, though most 
of them have been introduced more than twenty years 
ago. The species arc, R. indioa, R. hoc nos lemon, brown 
staraened. R. rubrum, red, and R. snlicifolia, willow- 
leaved. 
Rhododendbon abbobeum (Tlie Tree Rhododendron). 
—Though this line species is strictly a conservatory 
plant; yet it may be planted with a good effect against 
a wall. It is so nearly hardy, that no artificial heat is 
required to protect it. It flowers so early, that the 
blossoms are always injured by late frosts, if they are 
cultivated in tho open air. Tho splendid trusses of 
bloom of a dazzling scarlet, bright crimson, rich pur])le, 
and pure white, render all the varieties desirable 
plants for a glass-covered wall. They all require a 
large mixture of sandy peat amongst the soil. 
RnoDODENBRON CAMPANULATUJi (Bcll-flowered Rhodo¬ 
dendron).— This distinct species is not quite hardy, 
and though a slow grower is well deserving a place 
against a sheltered wall. The flowers are of a pleasing 
pink hue, spotted with brownish crimson. 
lliionoDENDBON GiBsoNii (Mr. Gibson’s Rhododen¬ 
dron, sometimes called R. formosum). —It is a fast grow¬ 
ing species, with foliage like an Azalea. The flowers 
are very largo, of a blush-white colour, and are generally 
produced in pairs, from the axils of the leaves, towards 
the ends of the shoots. They are slightly perfumed. 
It requires protection from frost. It is a most beautiful 
species, and should be grown in every collection. 
Rosa (The Rose).—If the preservatory is on a large 
scale, a few of the best Tea Roses and hybrid China 
Roses may be planted with good effect; they will bloom 
early and late, and will not be injured by heavy rains, 
or late and early frosts. 
ScHOTiA Speciosa (Sliowy Schotia).—A plant from 
the Capo of Good Hope; very seldom seen in flower; 
bnt, when planted against a wall covered with glass, it 
will bloom freely when old. The flowers are produced 
at the ends of tho strong short shoots: hence these only 
should be loft on the tree; all weak ones should be 
pruned away. 
Siphocampylos betdl,efolius (Birch - leaved Sipho- 
campylos).—It is not generally known that this hand¬ 
some freo-flowering plant is generally hardy, as is also 
S. bicolor. They are both worthy of a place against a 
glass-covered wall, on account of their pretty flowers, 
which arc produced all the summer. In such a situation 
they grow much finer than in a pot. Tho first has red 
flowers, and the other rod and yellow blooms. 
SoLLYA. —A genus of half-hardy climbers. I do not 
generally advise the planting of climbers against a wall 
j of this description, because they would overrun more 
valuable plants; but this genus is an exception. They 
are twiners, and will run iqi and twist I’ound a wire, or 
wires, which should be placed behind the plants for that 
purpose. Their foliage is small, and, therefore, will not 
shade other plants ; and their flowers are of a pleasing 
; blue colour, and produced profusely, tho whole length of 
I the shoots. The species suitable arc S. angustifolia 
i (Narrow-leaved); N. heterojdiglla (Various-leaved); S. 
linearis (Narrow-leaved); and S. salicifolia (Willow¬ 
leaved). If these four species are procured, and planted 
at equal distances, and upright wire rods fixed a little 
distance from tho wall, for the shoots to twine round, 
they will produce a good effect. 
Stbanvesia glaucescens (Grey Stranvesia).—A rare, 
and almost evergreen, shrub from Nepaul, with white
