_Ghent_ or _American Azaleas_. These are extremely popular hardy

deciduous shrubs. When plants are grown in the open, artificial

crossing will be unnecessary; but this method must be employed upon

those grown in the cool greenhouse, if well fertilised seeds are

required. The seed should be gathered and sown when ripe in a large

shallow frame containing from 2in. to 3in. of peat, over which more

peat must be laid very level by means of a fine sieve; or they may be

kept until early the following spring. No covering will be necessary,

but a thorough watering with a fine-rosed water-pot must be given.

The lights should be darkened, and the frames kept close until the

young seedlings begin to appear, when they must have air (carefully

admitted), shade, and a daily sprinkling of water. By the autumn, they

will be large enough to transplant in small clumps into boxes of peat

and coarse sand, and to place in other frames, or in the open. In each

case, they will need watering, shading, and to be kept close until

growth commences. The hardier the plants are before winter commences,

the better; but a protection of mats or similar material will prevent

the probability of their being killed by severe frosts. During the

following season, they will only require water during dry weather,

and no protection need be afforded this winter. The next spring, they

should be planted out singly in beds, sufficiently wide apart to allow

the development of two years growth. If an upright growth is being

made, the leading shoot must be shortened, in order to secure dwarf,

well-branched plants. The same methods should be employed on a smaller

scale where but a few are wanted. Grafting is largely practised to

increase the stock of named varieties or choice seedlings, the stock

employed being _A. pontica_. This process, of course, ensures the

quicker production of flowering plants. Layering in March, encasing

the part buried with moss, is also some times practised; but the layer

must be left two years before separating. Cuttings of the last year's

wood, 2in. or 3in. long, taken with a heel, root readily in sand; about

the end of August is the best time for so doing. If they are pricked

off in pots or pans of sandy soil, and kept in a cool frame until

they are calloused, and afterwards introduced into a slight bottom

heat, they root quicker, but this is not absolutely essential. When

placed outside, they should be covered with a handlight for about two

months, and, at the end of this time, air should be gradually given

and increased. Ghent Azaleas are now forced extensively for the market

as well as in private gardens; and, by judicious culture, they can be

had in full blossom by Christmas. With this end in view, they should

be grown in pots, and have the growth prematurely completed soon after

flowering with the aid of a little artificial heat; after which they

may be placed outside. During very hot and dry weather, the north side

of a wall is necessary, to prevent their flowering in the autumn. The

same plants must only be forced every alternate year. Commence to place

the plants in heat in October, and keep up a succession until the

following March. The best plants for forcing purposes are obtained from

the Continent, where they are grown in enormous quantities. When grown

permanently out of doors, the most suitable soil is peat and rough sand

mixed. Failing this, leaf mould, maiden loam, and sand, will be found

satisfactory. In many cases, we have known them to flourish in ordinary

garden soil.

The following varieties of Ghent Azaleas are distinct, and all

=A. arborescens= (tree-like).* _fl._ large, reddish, not clammy,

leafy; tube of corolla longer than the segments; calyx leafy, with

the segments oblong and acute. May. _l._, of the flower buds large,

yellowish-brown, surrounded with a fringed white border, obovate,

rather obtuse, smooth on both surfaces, glaucous beneath, ciliated

on the margins, and having the midrib almost smooth. _h._ 10ft. to

20ft. Pennsylvania, 1818. Deciduous species.

=A. balsaminæflora= (Balsam-flowered).* _fl._ bright salmony

red, finely double and rosette-like, the segments regularly

imbricated, much resembling in general appearance the blooms of

a Camellia-flowered Balsam. Japan. It is a distinct species,

and remains in bloom for a considerable period; the flowers are

invaluable for bouquets. See Fig. 196, for which we are indebted to

Mr. Bull.

=A. calendulacea= (Marigold-like).* _fl._ yellow, red, orange, and

copper coloured, large, not clammy, rather naked; tube of corolla

hairy, shorter than the segments. May. _l._ oblong, pubescent on

both surfaces, at length hairy. _h._ 2ft. to 6ft. Pennsylvania to

Carolina, 1806. This is said to be the handsomest shrub in North

America. There are several varieties of it in cultivation. Hardy;

deciduous. (B. M. 1721, 2143.)

=A. hispida= (bristly). _fl._ white, with a red border and a

tinge of red on the tube, which is wide and scarcely longer

than the segments, very clammy, leafy; stamens ten. July. _l._

long-lanceolate, hispid above, and smooth beneath, glaucous on both

surfaces, ciliated on the margins, and having the nerve bristly

beneath. Branches straight, and very hispid. _h._ 10ft. to 15ft.

New York, &c., 1734. A hardy deciduous species. (W. D. B. 1, 6.)

[Illustration: FIG. 197. FLOWER OF AZALEA LEDIFOLIA.]

=A. ledifolia= (Ledum-leaved).* _fl._ pure white, showy; corolla

campanulate; in threes at the extremities of the branches; calyx

erect, glandular, and viscid. March. _l._ elliptic-lanceolate. _h._

2ft. to 6ft. China, 1819. The whole shrub is very hairy. Hardy;

evergreen. SYN. _A. liliiflora_. See Fig. 197. (B. M. 2901.)

=A. liliiflora= (lily-flowered). Synonymous with _A. ledifolia_.

=A. nudiflora= (naked-flowered).* _fl._ in terminal clustered

racemes, appearing before the leaves, rather naked, not

clammy; tube of corolla longer than the segments; teeth of

calyx short, rather rounded; stamens much exserted. June. _l._

lanceolate-oblong, nearly smooth and green on both surfaces,

ciliated on the margins, having the midrib bristly beneath, and

woolly above. _h._ 3ft. to 4ft. North America, 1734. This species

hybridises very freely with _A. calendulacea_, _A. pontica_, _A.

viscosa_, &c., and descriptive lists of a host of hybrids of almost

every conceivable shade, both double and single, are to be found in

continental and home catalogues, to which the reader is referred.

Hardy. (W. F. A., t. 36.)

=A. pontica= (Pontic).* _fl._ leafy, clammy; corolla funnel-shaped;

stamens very long. May. _l._ shining, ovate, oblong, pilose,

ciliated. _h._ 4ft. to 6ft. Levant, Caucasus, &c., 1793. The

varieties of this species are also numerous, differing principally

in the colour of the flowers and the hue of the leaves. The flowers

are of all shades, and frequently striped. The name generally

adopted, as above, must not be confounded with _Rhododendron

ponticum_. If the genus _Azalea_ is merged into Rhododendron, as is

done by most systematists, this plant must be called by Don's name,

_Rhododendron flavum_. (I. H. 1864, 415.)

=A. procumbens= (procumbent). _See_ =Loiseleria procumbens=.

=A. speciosa= (showy).* _fl._ scarlet and orange coloured; corolla

silky, with obtuse, ciliated, lanceolate, undulated segments; calyx

pubescent. May. _l._ lanceolate, ciliated, acute at both ends.

Branches hairy. _h._ 3ft. to 4ft. North America. The varieties

of above are several, varying in the shape of the leaves and the

colour of the flowers. (L. B. C. 1255)

=A. viscosa= (clammy).* _fl._ white, sweet-scented, in terminal

clusters, downy, clammy, leafy; tube of corolla as long as the

segments. July. _l._ oblong-ovate, acute, smooth, and green on both

surfaces, ciliated on the margins, having the midrib bristly. _h._

2ft. to 4ft. North America, 1734. Like nearly all species belonging

to this genus, the varieties are many, varying in the colour of the

flowers and otherwise. (T. S. M. 438.)

=A. v. nitida= (shining).* _fl._ white, tinged with red, clammy,

leafy; tube of corolla a little longer than the segments. April.

_l._ oblanceolate, rather mucronate, leathery, smooth on both

surfaces, shining above, having the nerve bristly beneath, with

revolute, ciliated margins. _h._ 2ft. to 4ft. New York, 1812.

Hardy; deciduous. (B. R. 5, 414.)

_Indian or Chinese Azaleas._ This is a section of greenhouse

evergreen varieties obtained from _A. indica_ (which _see_), blooming

continuously from November to June, or even later, and of the greatest

value for all purposes, whether for decoration, cutting, or exhibition.

Cultivation: Thorough drainage is essential, and a compost of half

peat, the other half made up of fibrous loam, leaf soil, and sand, in

equal quantities. They cannot have too much light and air, and may be

grown to almost any size by shifting from one pot to a size larger.

In repotting, the whole of the crocks should be taken away from the

base of the ball of soil and roots, and the top should also be removed

till the fine roots are reached. The plant should then be put in the

new pot, and the additional soil rammed firm, in order to prevent the

water running through it, and thus depriving the plant of any benefit

therefrom. In all cases, the roots near the stem must be above the

soil, so that the water may not sink in next the stem, or death will

most certainly ensue. After potting, for a few days the plants should

be kept close and freely syringed, and as the growth is completed,

they may be well hardened off. The best time for potting is after

flowering, before the new growth has been made. From October to June

the plants should be in the greenhouse, and during the other months in

a cold frame, or plunged in pots in the open; or, what is preferable

in favoured localities, planted out in prepared beds; they will thus

be kept cleaner, and the growth will be much superior. In autumn they

may be lifted and repotted, placing in a shady position for a few days.

Water in abundance must be given throughout the blooming and growing

season; and the plants must, on no account, be allowed to become dry.

At the same time, a proper amount of care is most essential, as an

excessive amount of moisture is equally as fatal as drought. Cuttings

should be placed in sand under a bell glass with moderate bottom heat;

half-ripened ones are preferable. They must be cut up to a joint--the

base of a leaf--the lower leaves for an inch stripped off, and the stem

stuck into the sand, which should lay, about an inch thick, on the top

of sandy peat soil; the bottom of the cuttings should reach, but not go

quite into, the soil. The whole should be covered with a bell glass,

which must be wiped dry every morning. Soon after the cuttings have

commenced growing, place them in small pots. They are also very largely

and easily increased by grafting; indeed, this is the only satisfactory

method of securing standards. Seeds may be sown similar to the last

section, but in the greenhouse, and, when well up, pricked out into

little pots 1in. apart. Azaleas are liable to the attacks of thrips and

red spider, the latter being especially troublesome if the plants are

in a dry position; frequent syringing will materially help to eradicate

both pests. If insufficient, syringe with a solution of Gishurst's

Compound.

=A. amœna= (pleasing). _fl._ almost campanulate, rich crimson,

about 1-1/2in. across, hose-in-hose conformation, produced in great

profusion. April. _l._ small, size of the common Box, hairy. _h._

1ft. China. This is an elegant little neat and compact growing

shrub, which has proved to be quite hardy in England. (B. M.

4728.) A very beautiful series of hybrids have been obtained by

crossing this species with _A. indica_, which are most serviceable

and free. The following are most desirable: LADY MUSGRAVE, light

carmine; MISS BUIST, pure white; MRS. CARMICHAEL, rich magenta,

shaded crimson; PRIME MINISTER, soft pink, deep shaded, very free;

PRINCESS BEATRICE, light mauve, very distinct and free; PRINCESS

MAUDE, rich magenta, rose shaded.

[Illustration: FIG. 198. FLOWER OF AZALEA INDICA.]

=A. indica= (Indian).* _fl._ campanulate, terminal, solitary or

twin; calycine teeth long-lanceolate, obtuse, ciliated, spreading.

_l._ cuneate-lanceolate, finely crenelated, covered with sharp,

close-pressed rigid hairs, attenuated at both ends. Branches

also covered with sharp, close-pressed, rigid hairs. _h._ 3ft.

to 6ft. China, 1808. See Fig. 198. There are a great number of

garden seedlings of the Indian Azalea, including every shade and

colour. A selection to any extent may be made from the nurserymen's

catalogues, but, for the guidance of the amateur, we have made a

rigid selection of the best double and single varieties.

and black spotted, a very fine variety; LA VICTOIRE, centre

reddish, white towards the edge, the upper petals spotted with

maroon-crimson; LOUIS VON BADEN, pure white, a grand variety;

MADAME CHARLES VAN ECKHAUTE, pure white, with beautifully crisped

edges, of excellent form and substance; MADAME VAN HOUTTE, richly

flaked with carmine and rose, very large and free; MARQUIS OF

LORNE, brilliant scarlet, of the finest form and substance; MRS.

TURNER, bright pink, white-margined, and spotted with crimson;

PRESIDENT VAN DEN HECKE, white, striped and speckled with crimson,

with a yellow centre; PRINCESS ALICE, pure white, one of the best;

REINE DES PAYS-BAS, rich violet-pink, margined with white; ROI

D'HOLLANDE, dark blood-red, spotted with black; SIGISMUND RUCKER,

=A. mollis= (soft). Synonymous with _A. sinensis_.

=A. sinensis= (Chinese). _fl._ campanulate, downy, flame coloured;

stamens equal in length to the petals. May. _l._ slowly deciduous,

elliptic, acutish, pilosely pubescent, feather-nerved, with

ciliated margins, greyish beneath. _h._ 3ft. to 4ft. China and

Japan. A large number of seedlings and hybrids from this species

are in cultivation, known under the name of Japanese Azaleas, and

all are valuable for the decoration of the cool conservatory, or

for outdoor work. SYN. _A. mollis_. (L. B. C. 885.)

=AZARA= (in honour of J. N. Azara, a Spanish promoter of science, but

of botany in particular). ORD. _Bixineæ_. Showy evergreen, hardy and

half-hardy shrubs, with alternate, simple, stalked stipulate leaves,

and fragrant flowers. They thrive well in a compost of loam, leaf

soil, and sand. Ripened cuttings root readily if placed in sand, under

glass, in slight heat. It is believed that all the species enumerated

will prove hardy if a slight winter protection in midland and northern

counties be afforded. This precaution will be unnecessary in more

southern parts.

=A. dentata= (toothed). _fl._ yellow; corymbs sessile,

few-flowered. June. _l._ ovate, serrated, scabrous, tomentose

beneath; stipules leafy, unequal in size. _h._ 12ft. Chili, 1830.

(B. R. 1728.)

=A. Gillesii= (Gilles').* _fl._ bright yellow; panicles axillary,

densely packed. Spring. _l._ large, Holly-like, ovate, coarsely

toothed, smooth. _h._ 15ft. Chili, 1859. (B. M. 5178.)

[Illustration: FIG. 199. AZARA MICROPHYLLA, showing Habit, and Foliage

(half natural size).]

=A. integrifolia= (entire-leaved).* _fl._ yellow, on numerous

short axillary spikes, of an aromatic fragrance. Autumn. _l._

obovate or oblong, entire, smooth; stipules equal, permanent. _h._

18ft. Chili (about Conception), 1832. The variegated-leaved form,

although rare, is very ornamental. The variegation consists of

greenish-yellow, with a blotch of dark green, and in a young state

edged with deep pink.

=A. microphylla= (small-leaved).* _fl._ greenish, corymbose,

succeeded by numerous small orange-coloured berries. Autumn. _l._

small, distichous, obovate, obtuse, dark-shining green. _h._ 12ft.

Chiloe and Valdavia, 1873. This shrub is very ornamental as a

standard, and also excellent for covering walls. Quite hardy. See

Fig. 199, for which we are indebted to Messrs. Veitch and Sons.

=BABIANA= (from _babianer_, the Dutch for baboon; in reference to

the bulbs being eaten by baboons). ORD. _Iridaceæ_. A genus of very

ornamental bulbous plants confined to the Cape of Good Hope, with the

exception of a single species, which is found in Socotra. Flowers

occasionally fragrant, and generally characterised by their rich

self-colours, or the striking contrast of very distinct hues in the

same flower; perianth regular and symmetrical, with six ovate divisions

(tube varying in length). Stems from 6in. to 9in. high, arising from

a small bulb-like corm, and bearing tapering plaited leaves, which

are usually more or less densely covered with long hairs; the scapes

are racemose, each bearing about six or more simultaneously expanding

flowers. They may be successfully grown in pots. By this plan there

is, perhaps, less danger of loss, and their flowering season can be

prolonged considerably. A light sandy compost, with a small proportion

of well-decayed manure, is required, and thorough drainage is also most

essential. Use 48 or 60-sized pots, placing four or five corms in the

former, and two or three in the latter, and keep moderately dry until

they commence to form roots. October is the best time to pot. As soon

as the plants appear above ground, water may be carefully given, and

the supply proportionately increased as the plants develop. Very weak

liquid manure, applied twice a week, just as the spikes are pushing up,

will be beneficial. When the flowers fade, and the stems show signs of

decay, the supply of water must be gradually decreased, thus inducing

the thorough maturation of the corms, upon which the next season's

display depends. When quite down, store the pots in a dry place till

the time for repotting arrives, when the corms should be carefully

cleaned, and all offsets separated, the latter being potted up in the

same way as the parent corms in order to produce flowering specimens;

or they may be kept in a pot of sand and planted in a warm border

outside in March. Outdoor culture: A sheltered, sunny, and well-drained

situation is most essential to success. Although not absolutely

necessary, it is preferable to replant every year in early spring,

placing the bulbs about 5in. or 6in. deep, with a little sand sprinkled

about them. Planting may, of course, be done in autumn, when it will be

necessary to cover with cocoa nut fibre refuse to the depth of 5in. or

6in. In warm, sheltered situations, the corms may remain undisturbed;

but, as a rule, it is desirable to remove them late in autumn, when

the leaves are dead, and store them in dry sand through the winter in

a cool, airy position, free of frost. Mixed Babianas may be purchased

from dealers at a cheap rate, and, for general purposes, they are best

to plant. Propagation may be effected by offsets and seeds. The former

is the best and quickest method. The offsets should be grown in boxes

or planted out in light rich soil until large enough for flowering.

Seeds sown in pans, and placed in a gentle heat, will grow at almost

any time; the young plants will require to be carefully transplanted

each season until they develop into blooming corms.
