Cladrastis amurensis (Amoor Yellow Wood)Amoorland; LeguminosæWhitish; JulyA very distinct shrub or small tree, which is perfectly hardy, and has peculiarly greyish-green leaves. The dense spikes of small, pea-shaped blossoms are showy when at their best. This has deep descending roots, and holds its own in sandy soils better than most shrubs.
*C. tinctoria (Virginian Yellow Wood. Syn. Virgilia lutea)North AmericaWhiteA tree, 30 feet high, clothed with large ornamental pinnate leaves, which die off a rich yellow. The flowers are white, and in dense drooping racemes. A fairly moist soil is necessary for this.
Clethra alnifoliaUnited States of America; EricaceæWhite; August and early SeptemberIn the United States of America the White Alder or Pepper Bush, as Clethra alnifolia is called, occurs as a native over a considerable area; hence several forms exist, but do not possess any strongly marked features, unless it be the variety tomentosa, which is certainly the most widely removed of all from the typical kind. As a rule the flowering period of the common White Alder extends throughout August and a little way into September, at which last-named period the variety tomentosa is just unfolding its earliest blossoms. As the number of flowering shrubs that are at their best during the latter part of September is very limited, the blooming of this variety of the Clethra at that time makes it valuable. The varietal name of tomentosa is derived from the whitish down on the undersides of the leaves, which serves to readily distinguish it from the other forms. The flower-spikes, too, are rather larger, while the blossoms are as in the others—white. The Clethras all form rather loose-growing bushes from 3 feet to 5 feet high, and delight in a moist soil of a peaty nature, such as that in which Rhododendrons, Azaleas, and others of that class flourish.
C. canescens (Syn. C. barbinervis)JapanMilky white; SummerA very handsome species with dark-green leaves and panicles of blossom. Well worth attention, but is yet rare.
Colutea arborescens (Bladder Senna)Mediterranean region; LeguminosæYellow; May and JuneA perfectly hardy, free growing, deciduous shrub, reaching a height of 8 to 12 feet, clothed with pretty divided leaves, and with a profusion of pea-shaped flowers, succeeded by large inflated seed-pods, which form a very noticeable feature. These pods are green, tinged with red. The Coluteas are very useful, as they will thrive in dry sandy soils where many shrubs would perish.
*C. cruenta, Syn. C. orientalis, and C. sanguinea.OrientReddishAfter the manner of the last, from which it differs in its glaucous leaves, reddish flowers, and deeper-tinted seed-pods. It is also somewhat dwarfer.
Coronilla Emerus (the Scorpion Senna Coronilla)Southern Europe; LeguminosæYellow-tinged red; May and JuneA free-growing bush 6 feet high, with a profusion of pea-shaped blossoms. It needs a well-drained, warm soil.
C. juncea (the Rush-like Coronilla)South of FranceBright yellowAn erect shrub less than a yard high, with rush-like shoots, suggesting those of the Spanish Broom, and also almost devoid of leaves. When in full bloom it is decidedly pretty.
*Corylopsis paucifloraJapan; HamamelideæPrimrose; Spring, before the leavesThis delightful little shrub, when fully grown, makes a dense bush, with branches 6 feet high. The leaves are small, thin in texture, prettily tinted when young, and again in autumn. The flowers are primrose-yellow in colour and fragrant. They are arranged from two to four together in drooping catkins from every node on the previous season's wood. Though it is quite hardy in other respects the flowers are easily damaged by frost.
C. spicataJapanAlso cowslip-coloured and scentedA shrub between 3 and 4 feet high, and better known than C. pauciflora. It flowers in spring before the leaves appear.
*Cratægus (Thorns). See p. [376].

CYTISUS CAPITATUS.

Name.Country or Origin and Natural Order.Colour and Season.General Remarks.
*Cytisus albus (White Spanish or Portuguese Broom)Spain and Portugal; introduced in 1752; LeguminosæWhite; MayA beautiful and popular Broom. It grows with great rapidity, and flowers bountifully and regularly. A bush 6 or 7 feet high, in full flower is a delightful picture, and one never seems to tire of it. Group it with the common Broom. It is very cheap and easily raised from seed. Loudon says: "In good soil it is of very rapid growth, attaining the height of 5 feet or 6 feet in three or four years, and in six or eight years growing as high as 15 feet or even 20 feet if in a sheltered situation. Placed by itself on a lawn it forms a singularly ornamental plant, even when not in flower, by the varied disposition and tufting of its twiggy thread-like branches. When in flower it is one of the finest ornaments of the garden." Loudon also says that bees are fond of the flowers.
C. albus incarnatusVarietyPinkishRare, and not so beautiful as the parent.
*C. ArdoiniMaritime AlpsPure yellow; April and MayQuite a dwarf Broom, a few inches high. It is a charming Broom for the rock garden, placing it where it can spread out its shoots on all sides. It is happiest in sun and dry soil as the other Brooms.
*C. austriacus (Austrian Broom)Native of Austrian woods, also of Italy and Siberia. Introduced in 1741Yellow; July and AugustC. banaticus and C. serotinus are synonyms. The chief value of this Broom is in its late flowering, when its yellow flower clusters are very welcome.
C. a. leucanthusVarietyVery pale yellow, sometimes almost whiteNot important.
C. biflorusHungaryBright yellow; MayThis is not so important as the Moonlight Broom, Andreanus, and some others. It grows about 3 feet high, but even in a group it is not imposing.
C. capitatusFound on wood edges in Austria and introduced in 1774Yellow; JuneThis is also a dwarf and not important Broom.
C. hirsutusAsia Minor and South of Europe. Introduced in 1739Yellow; JuneThis is another dwarf and unimportant shrub.
*C. kewensisHybrid between C. albus and C. ArdoiniCreamy white; MayA most interesting and beautiful Broom, which, as it becomes better known, will be popular in gardens. It was raised in the Royal Gardens, Kew; hence the name, C. Ardoini being the seed parent. It is only suitable for the rock garden, where its slender shoots can spread out and form a mantle of soft colouring, or to make a spreading group on the grass. There is little trace in it of C. albus, except in the flower colouring. This is a Broom for all good gardens.
*C. nigricansAustriaBright yellow; July and AugustThis is also a lovely Broom, so named because it turns black when dried. It should be in the smallest list of beautiful flowering shrubs, and it is singular that it is so seldom seen. The growth is bushy and smothered with flowers in July and August, sometimes before, and lasts a long while in beauty. Sunshine and poor soil bring out its finest qualities. One can scarcely say too much in its praise, especially as it blooms at a time few trees and shrubs are in flower.
*C. præcoxHybrid between C. purgans and C. albusSulphur yellow; April to May One of the most fascinating of all flowering shrubs. It makes clouds of soft colouring, every shoot hidden with the wealth of bloom; whilst when out of flower there is beauty in the brilliant green colouring of the long slender shoots. It is a shrub to make groups of in the flower garden, grows quickly, does not soon get "leggy," and is very dense. The big groups of it on the grass in the Royal Gardens, Kew, are one of the delights of the spring season there. The ordinary shrubbery is the worst place for it, all its gracefulness is lost, there is no fountain of flowers from the slender shoots. It is best raised from cuttings, as seedlings are apt to reproduce C. albus only. Also well known as Genista præcox.
C. purgansSouth and Central EuropeYellowChiefly of note because it is one of the parents of C. præcox, but is of little account for the English garden. It is necessary in a collection, but nowhere else.
*C. purpureusFound in Eastern Europe in exposed situationsPurpleA delightful shrub when properly placed. Loudon's advice to graft it "on the laburnum standard high" is bad, and has been followed in many gardens. This way of treating the shrub is utterly foreign to its nature; it is a trailing Broom, and therefore should be planted on the rough garden or some bank where it can spread in its own way. We have seen it falling over a boulder and making a trail of purple colouring in May. Rare varieties are albus, white, and one with flowers of rose tint. The famous Cytisus Adami is the outcome of grafting this species on the Scotch laburnum (L. alpinum). This curious graft-hybrid usually excites much interest when in flower, both yellow and purple racemes appearing on the same tree.
C. sessilifoliusA native of the south of France and Piedmont, and was cultivated in Britain by Parkinson in 1569.Yellow; MayA Broom for a collection, but without the effectiveness of C. præcox, Andreanus, and others.
C. SchipkænsisIntroducedWhiteThis is a charming little rock-garden shrub, and very rare as yet, but well worth noting for its distinctiveness and freedom.
*C. scoparius (Common Broom)EuropeYellowThe hardy Cytisuses are popularly known as Brooms, and the Broom of the waste lands of the British Isles is Cytisus scoparius, which makes clouds of golden yellow in the early summer. Many a dryish bank now flowerless might be made beautiful with this glorious shrub. Where Broom is not plentiful as a wild plant, and therefore generally where the soil is not suitable for it, the soil should be made so; it need only be well drained and open.
*C. s. andreanusChoice variety found in Normandy by M. Ed. André, after whom it is namedBrownish crimson and yellow; SpringThis varies considerably from seed, and often reverts to the typical yellow Broom. If possible get own root-plants from original stock. A beautiful shrub, which we can scarcely have too much of, but in some gardens it is used too freely. When in full bloom, and the variety is rich in colouring, it is superb.
C. s. pendulus (Drooping Broom)VarietyPale yellowQuite a pendulous variety, but uncommon. It is apparently little known, though so charming when on a bank or rock garden. A group of it in either of these positions would be a revelation to those who know not the value of this family for the English garden.
*C. s. sulphureus (pallidus), (Moonlight Broom)VarietyPale yellowDescribed by Loudon in his "Arboretum" as C. s. albus, "the flowers white or of a very pale yellow." It is a rare shrub, but should not be so. Mr. Goldring writes of it in "The Garden" as follows: "The Moonlight Brown is a very old variety, as it was described by Loudon sixty years ago, but it is still a rare shrub, not easily obtainable, though it is grown in some of the largest nurseries. Its pale yellow flowers are in beautiful harmony with the rich yellow of the type Andreanus. The only private garden where I have seen it in established mass is that of Mrs. Robb at Liphook, where all kinds of tree and shrub varieties are treasured. I do not know if it comes true from seed, but I fancy not."
C. s. flore-plenoVarietyYellowA so-called double variety in which some of the petals are duplicated, but it is not finer than the type, though it is interesting as one of the few double varieties in pea-shaped flowers.

A HYBRID BROOM (Cytisus kewensis) AT KEW.

Name.Country or Origin and Natural Order.Colour and Season.General Remarks.
Cratægus (Thorns)Rosaceæ The Cratægus family comprises nearly 100 species and varieties, contains some of the most beautiful of small garden trees, both with regard to the charm of their white, pink, and scarlet flowers, and the scarlet, black, and yellow fruits. Most of the Thorns are either large shrubs or small trees, and are specially suitable for small gardens, whilst none of them require particular attention, as all will grow in almost any soil and situation. Old trees occasionally require to be relieved of small wood and decaying branches, and a good top-dressing of manure is beneficial sometimes to those which flower and fruit freely; but beyond this Thorns need no attention after they have been planted and become established. The species can be increased by seeds, which are obtained by gathering the fruits when ripe, and mixing them with sand. The mixture of fruits and sand should then be put in a heap in a sheltered place out-of-doors, and covered with a few turfs. By the following spring the fruits will have rotted, and the seeds can be separated and sown. A fair proportion will germinate the first year, and the remainder the second. Many of the Thorns can also be propagated by root cuttings. For this purpose healthy, vigorous shoots, as thick as a man's finger, should be obtained in autumn or winter, and cut into pieces four inches to eight inches in length, cutting the end nearest the stem flat, and the other slanting, so that either end can be readily distinguished. These should be inserted upright in the ground, with the tops nearly or just covered; they soon form roots, and grow into strong plants. The genus is found practically throughout the temperate region, from Europe throughout the East and Central Asia to China and Japan, and in North America. One species is found in Mexico—but this, and in fact all the Thorns are hardy in this country.
*C. AzarolusSouth-East Europe and Asia MinorPure white; late SpringThis grows to a height of about 20 feet. It is very showy, and has pure white flowers followed by large yellow fruits; the leaves are about twice the size of those of the Hawthorn, and rather deeply cut. Cratægus Aronia is a synonym.
*C. CarrièreiA reputed hybrid, but parentage unknown. Supposed to be C. mexicana and C. tomentosaPure white; late SpringA very handsome Thorn, 12 feet to 15 feet, shapely, leaves large, bright glossy green above, whitish beneath. Flowers appear freely in large corymbs, followed by clusters of pear-shaped green fruits, which hang on the tree until the end of the year, changing finally to dull, yellowish red.
*C. coccinea (the Scarlet Thorn)North America; introduced in 1683White; late SpringThis is one of the most striking of all the thorns; it has large bright-green leaves, and flowers nearly an inch across, and in dense corymbs. These are followed by clusters of brilliant scarlet-coloured fruits. There are several varieties equal to or even finer than the species. One is *Macracantha, which has spines sometimes 5 inches long, and bright scarlet haws, not so large as those of the species, but produced more abundantly. It should be more frequently seen in gardens, and is worthy to rank as a species. Indentata has deeply-cut leaves and bright-red fruits.
*C. cordata (Washington Thorn)North AmericaWhite; JuneThis is a small tree with thin, glossy, heart-shaped leaves and small flowers, orange-red fruits, not unlike those of C. Pyracantha, and carried late in the year. Birds, however, enjoy them.
C. Crus-Galli (the Cockspur Thorn)North AmericaWhite; JuneThis is a handsome American Thorn, and one of the most striking of the whole family. It has stout, glossy leaves and formidable spines, these often being from 3 to 4 inches long, and gave rise to the popular name. The brick-red fruits hang on the tree long after the leaves have fallen, and make a bright winter picture. There are several varieties. Arbutifolia has shorter spines and smaller fruits than the type; the leaves are also narrower and duller in colour; linearis has long linear leaves and bright-red fruits. Ovalifolia has large oval shining leaves and bright scarlet fruits, it is rather more upright han the type. *Splendens makes a handsome, shapely tree about 20 feet high, and flowers and fruits very freely; the leaves are rounded, green, and shining, and the flowers pure white, in small corymbs, and followed by bright-scarlet fruits.
C. DouglasiiWestern side of North AmericaWhite; late SpringThis is a large irregular-shaped tree 20 feet to 30 feet, and has short stout spines about an inch long; the flowers appear in small clusters, and the fruits are small and black. Wood and spines are brown and quite shiny. Rivularis has smaller and thicker leaves, and shorter and stouter wood.
C. hiemalisProbably a hybrid, but origin unknownWhite; SpringA tree 15 feet to 20 feet high, round shining leaves, and rather large black fruits, which are the first to ripen of the Thorns.
*C. melanocarpaCaucasusWhite; SpringA very handsome Thorn. It is a small flat-topped tree of medium height, the leaves somewhat like those of the Hawthorn in shape, and covered with a thick grey tomentum; the fruits are small, black, and shining.
C. mollisUnited StatesWhite, with a small red mark at the base of each petalLike C. coccinea, but even handsomer. It is a small tree, 15 feet high, with spreading head, and large firm leaves slightly woolly on the back; the flowers are large, and succeeded by bright-crimson, medium-sized fruit.
C. nigraEastern EuropeWhite; MayThis makes a fair-sized tree, and has small black fruit. The foliage is very abundant, deeply cut, and woolly on both sides. It almost hides flowers and fruit.
*C. orientalisEuropeWhite; MayA handsome Thorn in fruit. It is a small flat-topped tree, and has large clusters of flowers, the oval fruits being yellowish red. Sanguinea is a very showy variety, with deep ruby-red fruits, but the scarlet colour of the type is brighter.
*C. Oxyacantha (Hawthorn, White Thorn, May)Widely distributed, Europe, Western Asia, and North AfricaWhite; MayToo well known to describe. It has been divided into two sub-species, viz. C. monogyna in which there is usually only one style in the flowers and one seed in the fruit, and C. oxyacanthoides, where the number of styles is usually three, and from two to four seeds in the fruit. These differences are generally decided. There are other differences also in growth difficult to explain, but can be detected easily by an experienced eye.
C. monogyna (sub-species)............This is the Hawthorn of the hedgerows, and there are many varieties. Twenty-eight are recorded in the Kew Hand-list. The most beautiful are aurea, with golden-yellow haws, crispa pendula, a pretty weeping tree; Gumperi versicolor, very handsome deep-red, shading to pink in the centre; laciniata, a handsome tree with deeply cut leaves, sometimes called C. apiifolia, but must not be confounded with North American species of that name. Macrocarpa has larger fruits than the type, oxyphylla, large white flowers and handsome fruits, a round-headed tree. Præcox is the Glastonbury Thorn, supposed to flower at Christmas, but rarely does so owing to frost. This is the Thorn which is associated with the famous legend. *Semperflorens is a good variety, a low-growing tree, which flowers for a much longer period than the other Thorns. Stricta makes a dense upright-growing tree, 30 feet or more high; it grows rapidly, and when in flower is strikingly distinct in appearance.
C. oxyacanthoides (sub-species)............This is distinguished from C. monogyna by the styles and seeds as stated above; and also by the larger leaves, flowers, and fruit. All the double-flowered Thorns belong to this section. Atrofusca, a large, shapely tree, of weeping growth; the flowers large, pure white, and the fruits fair sized and abundantly produced. *Flore-pleno albo, the double white Thorn, with purest white flowers. This, like the other double Thorns, rarely fruits. *Flore-pleno coccineo, the double Scarlet Thorn, one of the most beautiful of trees when covered with its scarlet flowers. Very pleasing when grouped with the double white variety or the Laburnum; *Paul's double Scarlet, a well-known and beautiful Thorn. *Flore puniceo, a rich purplish pink, single, and fructu luteo, bright yellow fruits, effective in autumn.
*C. pinnatifidaChina and Central AsiaPure white; MayThe variety *major is the best to grow. It is stronger, and has very large leaves, 4 to 6 inches long, thick and shining. It does not show its true beauty until of some age, but it is a hardy tree of great beauty. The flowers are in large corymbs, and the fruits are of an intense shining red, pear-shaped, and make a bright picture in autumn. This variety is often labelled C. Layi.
*C. punctataEast and North AmericaVariableA good garden tree; it is variable, but the accepted type has white flowers and bright red fruits as large as a small Crab apple. Another form has smaller deep ruby-red fruits. Brevispina, striata, and xanthocarpa are varieties, the last mentioned with bright yellow fruits.
*C. Pyracantha (Fiery Thorn)South Europe, in hedges and rough groundWhiteAn evergreen Thorn. Introduced in 1629, and a well known shrub. Its charms consist in its dense glossy leaves and brilliant masses of scarlet berries. It can be grown as a bush or trained up a wall or trellis. It is so brilliant when in fruit that the French call it buisson ardent, or Burning Bush. This Thorn should be more grown as a bush, and not confined as it usually is to a south wall. As the fruits are bitter they are not cared for by the birds, and thus make a display through the winter. Lælandi is a variety with larger and deeper coloured fruits.
C. sanguineaSiberiaWhite; MayThis is not of great garden value, but effective in winter owing to the red bark. Songorica is a variety also with reddish bark.
*C. tanacetifolia (Tansy-leaved Thorn)Levant; introduced 1789White; MayThis is rare, and can be recognised by bracts at the base of the fruits. The fruits are very large, yellow, and of good flavour, and eaten in the native country of the tree. The specimen at Kew flowers regularly and abundantly every year.
C. spathulataUnited StatesWhite; MayA very distinct Thorn, small, and the leaves are persistent, remaining on until the New Year. The fruits are very small and scarlet.
*C. tomentosaEastern United StatesWhite; JuneA late flowering and handsome Thorn when its orange-yellow fruits are in perfection, but the birds soon consume them.
C. unifloraNorth America, and introduced by the famous tree bishop, Bishop Compton, in 1713Creamy white; early JuneMore curious than beautiful; it is only 2 feet to 3 feet high and has greenish haws.
Name.Country or Origin and Natural Order.Colour and Season.General Remarks.
Cyrilla racemifloraFlorida to North Carolina, &c. CyrilleaWhiteQuite a shrub, 4 feet to 6 feet high, very rare, although introduced as long ago as 1765. The flowers are in drooping racemes on previous season's growth.
*Daboëcia polifolia, St. Daboëc's Heath (Syn. Andromeda Daboëcia)Western Europe and Ireland; EricaceæRosy purple, bell-shaped; May, and throughout Summer and AutumnA pretty little Heath-like shrub growing about 18 inches high, and producing erect spikes of comparatively large bell-shaped blossoms. It is the most continuous blooming of its class. There is a beautiful pure white variety—alba.
Daphne alpina (Alpine Daphne)Alps of Europe; ThymelæaceæWhite; May and JuneA spreading deciduous shrub, with white, sweet-scented flowers. It grows about a couple of feet high, and is essentially a shrub for the rockwork, as it is particularly happy when the roots are wedged between stones.
*D. blagayanaCarniolaIvory white; March and AprilLike the last, this forms a spreading bush, and is equally at home under similar positions. It is, however, of an evergreen character; the ivory white are very sweet-scented blossoms. It is worthy of a place among the most select Daphnes, but difficult to grow well.
*D. Cneorum (Garland Flower)South EuropeBright rose; May to JuneA delightful little evergreen, with highly fragrant blossoms. A good proportion of vegetable soil is necessary to its welldoing.
D. Genkwa (Japanese Lilac)JapanLilacIn its flowers this Daphne closely resembles the Lilac, so that it is frequently mistaken for that well-known shrub. It needs the protection of a wall in most parts of England.
D. Laureola (Spurge Laurel)South Europe and North AfricaYellowish greenThe flowers of this are not particularly showy, but as an evergreen bush some 3 or 4 feet high it is valuable from the fact that it will thrive under the drip of trees, and is one of the few evergreens absolutely rabbit proof.
*D. Mezereum (the Mezereon)Northern EuropeRed; early yearThis is an upright deciduous bush that flowers in February or March according to the season. At that time the still leafless branches are packed for some distance with the pretty fragrant blossoms, so that it may be regarded as the most showy shrub at that time in bloom. There is a variety (alba) with white blossoms, and another (autumnalis or grandiflora) that blooms before Christmas. A cool, loamy soil suits this best.
*D. oleoides (Syn. D. fioniana, Syn. D. neapolitana)South EuropePurplish roseA neat growing evergreen bush about a yard high, whose flowers are often borne throughout the greater part of the year. It is less attractive than some of the others.
D. ponticaAsia MinorYellowA good deal in the way of Daphne Laureola, but the flowers are of a brighter yellow, and are borne in April and May, whereas D. Laureola flowers in February and March.
D. sericea (Syn. D. collina) Deep pinkA compact evergreen 2 to 3 feet high, clothed with dark-green box-like leaves, while the terminal clusters of flowers are borne in early Spring. It prefers a cool, fairly moist, yet well-drained soil.
