Chapter 7

It enjoys a sandy loam in a moist but warm situation; at the base of a small rockwork having a southern aspect it flourishes to perfection; it can hardly be planted wrongly provided there is no stagnant moisture. Propagated like _C. autumnale_, than which it is of slower increase.

Flowering period, September and October.

Coreopsis Auriculata.

EAR-LEAVED COREOPSIS; _Nat. Ord._ COMPOSITÆ.

The oldest species of the genus grown in English gardens; its flowers are yellow, but dotted at the base of the ray florets. The leaves, as implied by the name, are dissimilar to other species, being lobed and having ear-like appendages; but this feature is far from constant, and otherwise the leaves differ, being sub-sessile and oval-lance-shaped (see Fig. 26). It came from North America as long ago as 1699. Slugs are very fond of these plants, and in winter more especially, when the dormant eyes are not only in a green, but exposed state; they should be watched after, or during one mild night the whole may be grazed off, to the great injury of the plant.

Its habit, uses, culture, and propagation are the same as for _C. tenuifolia_.

Coreopsis Grandiflora.

LARGE-FLOWERED COREOPSIS; _Nat. Ord._ COMPOSITÆ.

In many parts this resembles _C. lanceolata_, its main distinction being implied by its name. The flowers are larger and the ray florets more deeply cut; it is also bolder in the foliage, and the stems grow nearly as strong as willows. It is an abundant bloomer, and a good specimen is a glorious object during the autumn. It comes from North America, but my experience of it is that it is not so hardy as _C. lanceolata_ and _C. auriculata_.

Habit, uses, culture, and propagation, as for _C. lanceolata_.

Coreopsis Lanceolata.

SPEAR-LEAVED COREOPSIS; _Nat. Ord._ COMPOSITÆ.

This form of bright yellow flower is in great favour during August, but that is not all. The various kinds of this genus are plants of the easiest culture, and their rich flowers are produced in great quantities from midsummer to the time the frosts begin. This species has been said to be only of a biennial character; it is, however, understood generally to be perennial, though not quite so hardy as others which come from the colder climates of America. It was imported from Carolina in 1724, and in this country proves hardy in selected situations, where its roots are comparatively dry in winter, and I may add that it proves a true perennial.

When the plant has attained the height of a foot it begins to flower; each bloom has a long pedicel, nearly naked, also round and smooth. The flowers are a shining yellow colour, and nearly 3in. across; the florets of the ray are flatly arranged, shield-shaped, pleated, and four-toothed, the teeth being sometimes jagged; the disk is small for so large a flower; the florets brown and yellow. The double involucrum, common to the genus, has its upper set of bracteoles rolled outward; they are of a brownish colour; the lower set are green and wheel-shaped during the period of a perfect ray, and they alternate with the upper ones. The leaves, as may be inferred from the specific name, are lance-shaped, 2in. to 6in. long, smooth and entire; they are attenuated to the stems, which they more or less clasp. The habit of the plant is much branched, but only slightly at base; it becomes top-heavy from the numerous shoots near the top, which cause it to be procumbent; otherwise this subject would rank with tall growers. It is one of the most useful flowers, both, in the garden and when cut, the long stalks in both cases adding much to its effectiveness; its form and brightness are sure to commend it, no matter whether it happens to be a fashionable flower or otherwise. It is at once a bold and delicate form, and one that harmonises with any other kinds and colours.

It should be grown in deeply-dug and well-enriched earth, and, as already hinted, the drier the situation the more safely will it winter. Not only that, but on raised beds or banks sloping to the full sunshine it will also flower to perfection. All its family, so far as I have proved them, hate excessive moisture. Its propagation may be by division, as in this damp climate it does not seem to ripen seed, but I have found sometimes not a little difficulty in dividing the woody roots, as frequently there is only one stem below the surface with roots. When there are more the difficulty is lessened, but I have noticed that the stronger branches which are weighted to the ground form rudimentary roots where in contact with the earth. These may either be pegged and covered with soil, or cut off and made into cuttings, removing most of the tops. If the latter is done during August they will become well rooted before the frosts appear.

Flowering period, July to October.

Coreopsis Tenuifolia.

SLENDER-LEAVED COREOPSIS; _Nat. Ord._ COMPOSITÆ.

Hardy, herbaceous, and perennial; a native of North America, and a distinct species, from its finely-cut foliage and small, dark, orange-yellow flowers. For several weeks it has a few flowers, but during September it literally covers itself with bloom, so that it is one of the most pleasing objects in the garden.

It grows 2 ft. high; each flower has a long nearly nude stalk, slender but wiry; the flowers are 1½in. across, and of a deep yellow colour; the florets of the ray are more distant from each other than is the case with many of the genus; the disk is small, dark brown, but changing from the appearance and disappearance of the yellow seed organs. The foliage, as may be seen by the illustration (Fig. 27), is deeply and finely cut, of a dark green colour, and so arranged that each node has a nearly uniform dressing; the main stems are slender, and bend gracefully with the least breeze, and otherwise this plant proves a lively subject. Its habit is bushy and very floriferous, and it is well worth a place in every garden. It cannot fail to win admiration; even when growing, and before the flowers appear, it is a refreshing plant to look upon. In a cut state, the bloom, if taken with long stems, is well adapted for relieving large and more formal kinds. Tastes differ, and in, perhaps, nothing more than floral decorations; all tastes have a right to a share of indulgence, and in claiming my privilege in the use of this flower, I should place two or three sprays (stems) alone in a glass or bright vase, but there might be added a spike of the cardinal flower or a pair of single dahlias and a falling spray of the Flame nasturtium (_Tropæolum speciosum_).

This plant should have a rich soil, sunny aspect, and a raised or well-drained site, and this is all it needs; it is not a subject to increase fast; not only, however, may it be easily divided, but if properly done after the tops have died down, the smallest pieces will make good blooming stock the first season.

Flowering period, August and September.

Cornus Canadensis.

CANADIAN CORNELL, _or_ DOGWOOD; _Nat. Ord._ CORNACEÆ.

This pretty herbaceous plant is sometimes said to be a British species; its specific name, however, somewhat forbids that opinion. _C. suecica_, which is British, is very similar in all its parts, and the two may have been confounded. They flower, however, at very different dates, _C. Canadensis_ beginning in June and continuing until well into autumn; during the month of August the flowers are in their finest form and greatest numbers. It grows 6in. to 8in. high, and notwithstanding its dwarfness, it proves a most attractive object, being not only conspicuous for so small a plant, but chastely beautiful.

The flowers are exceedingly small, strictly speaking, and are arranged in a minute umbel in the midst of a bract of four white pink-tinted leaves; these latter are commonly taken for the petals, and, as may be seen in the illustration (Fig 28), the real flowers will only appear as so many stamens; but at their earlier stage these are of a yellowish colour; later the purplish style becomes prominent and imparts that colour to the umbel, and, in due time, small fruit are formed. All the while the bract of pleasing white leaves remain in unimpaired condition; they are arranged in two pairs, one of larger size than the other, somewhat heart-shaped and bluntly-pointed, richly tinted at their edges and tips with a bright pink colour, and forming a flower-like bract 1½in. across the broadest part. The bract and pedicels of the umbel all spring from the extremity of a peduncle 1½in. long, square, but of wiry character; this grows from the midst of a whorl of six leaves, and sometimes only four. They are in pairs, one pair being larger than their fellows, and are from 1½in. to 2in. long, elliptical-oblong, entire, smooth, waved, distinctly veined, tinted with pink at the tips and edges, and of a pale apple-green colour. On the stem, below the whorl of leaves, there is one pair more, varying only in size, being rather less. The habit of the species is neatness itself. From the slightly creeping roots, the perennial stems are produced separately, forming compact colonies of bright foliage, topped with its lively bracts.

It is a suitable plant for the moist parts of rockwork, where it may be grown with such things as _Cardamine trifolia_, _Galax aphylla_, _Pyrola rotundifolia_, and _Salix reticulata_, and it would form a rich edging to choice dwarf plants, more especially if the position were gutter-formed, as it loves moisture in abundance. In such positions as those just mentioned, together with a light vegetable soil, this plant will grow to perfection, and that it is worth a proper place is evidenced by its long-continued blooming. Many flowers come and go during its period of attractiveness, and, after the summer flush, it is one to remain, braving alike the hot sunshine and heavy rain. Its propagation is by division of the roots in autumn or very early spring.

Flowering period, June to October.

Corydalis Lutea.

YELLOW FUMITORY; _Nat. Ord._ FUMARIACEÆ.

A native herbaceous perennial, though somewhat rare in a wild state. As grown in gardens, where it seems to appreciate cultural attentions, it proves both useful and effective, especially when placed in partial shade (when its foliage has an almost maiden-hair-like appearance), or as an edging it proves both neat and beautiful.

It seldom exceeds a foot in height. The flowers are small, a yellow, white and green mixture, the yellow predominating; they are produced in loose spare racemes, on well-foliaged diffuse stems, which are also angular; the calyx is composed of two leaves; the petals are four, forming a snapdragon-like flower. The leaves are bipinnate, leaflets wedge-shape, trifoliate, and glaucous; the foliage very dense, having a pretty drooping habit. It flowers all summer, and is one of the most useful plants in a garden to cut from, the foliage being more valuable than the flowers.

Its native habitats are said to be old walls and ruins, but I have proved it for years to do grandly in ordinary garden soil, both exposed and in the shade of fruit trees. When once established it propagates itself freely by seed. I ought to add that it answers admirably grown in pots for window decoration, the rich foliage nearly hiding the pot.

Flowering period, May to October.

Corydalis Nobilis.

NOBLE _or_ GREAT-FLOWERED CORYDALIS; _Nat. Ord._ FUMARIACEÆ.

A hardy tuberose perennial, imported from Siberia in 1783. It is one of that section of the Fumitories called "Hollowe Roote," the appropriateness of which name is most amply illustrated in the species now under consideration. If, in the first or second month of the year, a strong specimen is examined, the long and otherwise stout tuberous root will be found, immediately under the healthy and plump crown, to be not only hollow, but so decayed that the lower and heavy fleshy parts of the root, which are attached to the crown by a narrow and very thin portion of the root bark, in such a way as to suggest that the lower parts might as well be cut off as useless--but, let me say, do not cut it. If it is intended to replant the specimen, let it go back to "Mother Earth" with all its parts, deformed as some may seem to us; otherwise _Corydalis nobilis_ will be anything but a noble plant at the flowering season; it may not die, but it will probably make for itself another "hollowe roote" before it produces any flowers, The habit and form of this plant are perfect (see Fig. 29), and there are other points of excellence about it which cannot be shown by an engraving, in the way of the arrangements of colours and shades. Seldom does the little plant, so full of character, exceed a height of 8in. The specimen from which the drawing was made was 7in., and grown fully exposed in a pot plunged in sand. Another plant, grown on rockwork, "high and dry," is about the same size, but it looks better fed. Probably the long roots are short of depth in pots, and the amount of decay may soon poison the handful of mould contained therein. Be that as it may, the specimens grown in pots have a hungry appearance compared with those less confined at the roots.

The flowers are a pleasing mixture of white, yellow, brown, and green. The four petals are of such a shape and so arranged as to form a small snapdragon-like flower. These are densely produced in a terminal cluster in pyramid form on the stout and richly-foliaged stem; dense as is the head of flowers, every floret is alternated with a richly-cut leaf, both diminishing in size as they near the top. The older flowers become yellow, with two petals tipped with brown, the younger ones have more white and green, and the youngest are a rich blend of white and green; the head or truss is therefore very beautiful in both form and colour, and withal exquisitely scented, like peach blossom and lilac. The leaves are stalked bipinnate; leaflets three-parted, cut, and glaucous; there are few plants with more handsome foliage, and its beauty is further enhanced by the gracefully bending habit of the whole compound leaf. The flowers are too stiff for cutting, and otherwise their fine forms, colours, and perfume cannot well be enjoyed unless the plants are grown either in pots or at suitable elevations on rockwork, the latter being the more preferable way. The long blooming period of this plant adds not a little to its value, lasting, as it does, quite a month, the weather having little or no effect on the flowers.

Any kind of sweet garden soil seems to do for it, and its propagation is carried out by careful root division.

Flowering period, April to June.

Corydalis Solida.

_Common Name_, FUMITORY; _Nat. Ord._ FUMARIACEÆ.

This is said to be a British species, but it is a doubtful, as well as somewhat scarce one. Though but a small plant of the height of 6in. or 8in., it is very effective, being compact with finely-cut foliage of a pale glaucous green, and the stems pleasingly tinted. For some weeks in early spring it forms a graceful object on rockwork, where it seems to thrive well.

The flowers, which are purple, are not showy; still, they are effective from the way in which they are borne, as the illustration (Fig. 30) will show. Its specific name is in reference to its root, which is bulbous and solid. Many of the Fumitories have remarkably hollow roots, and one of the old names of this genus is written "Hollowe roote." When the flowers fade the whole plant withers, nothing being left but the bulbous roots to complete their ripening; still, this should not hinder its extensive cultivation, because it not only appears in its best form when flowers are rare, but also because it is so pleasingly distinct.

I find it to do well on rockwork, also in well-drained borders of light loam. It should be allowed to increase until it forms good-sized tufts, which it soon does. To propagate it, it is only necessary to divide the tubers any time from July to October.

Flowering period, February to May.

Crocus Medius.

_Nat. Ord._ IRIDACEÆ.

This is a charming kind, seldom seen and, perhaps, little known; the name would imply that it is a variety having equal traits of two other forms. It blooms in January and the flowers appear without any foliage. So well is the Crocus known, it will only be needful to state the more striking features of the one under notice.

The flowers are produced on tubes 3in. to 5in. long, and stoutly formed; the colour is a shaded lilac-purple, striped with darker lines; the petals or divisions of the perianth are 1½in. long and ½in. broad, shining or satiny, and become well expanded during the short moments of winter sunshine; the stamens are half the length of perianth, of a fine deep orange colour, and covered with a thick coat of pollen all their visible length. In rich contrast with these is the style, with its tuft of filaments of a bright orange scarlet colour. From this description it will be seen that the flower is a rather small Crocus, but from the soft tints of the perianth, and more pronounced and bright colours of the seed organs, it is one of much beauty. These features, added to the facts of the bloom appearing in winter and having the scent of wild roses, are sure to render it a favourite kind wherever grown. The leaves are short and narrow, almost grassy.

It enjoys a light but rich loam and sunny aspect, and increases itself freely by offsets of the matured corms, clumps of which may be divided after the foliage has withered.

Flowering period, January.

Cyananthus Lobatus.

_Nat. Ord._ POLEMONACEÆ.

A small plant with a large flower, a veritable gem; no collection of choice alpines can be complete without this species. A native of Chinese Tartary, brought to this country in 1844, where it proves perfectly hardy in the most exposed parts of the open garden; it is herbaceous and perennial; its large and brilliant flowers are very beautiful, but all its other parts are small, as may be seen in the illustration (Fig. 31). It is seldom met with except in collections of rare plants, but there is no reason why it should not be more commonly grown, as its requirements are now well understood. It is not a showy subject, but, when examined, it proves of exquisite beauty.

The flowers are of a bright purple-blue colour, over an inch across, the petals being of good substance, tongue-shaped, and falling backwards, when the china-like whiteness about the top of the tube becomes more exposed; the calyx is very large, nearly egg-shaped, having five finely-pointed and deeply-cut segments; the bulky-looking part, which has an inflated appearance, is neatly set on a slender stem, and densely furnished with short black hairs of even length; this dusky coat has a changeable effect, and adds not only to the character, but also to the beauty of the flower. The small attenuated leaves are alternate and laxly arranged on the flower stems, which are 6in. to 12in. long, round, and nearly red. Each leaf is less than 1in. long, distinctly lobed with five or more lobes, and all the edges are turned back, causing the foliage to appear thick and well finished; the foliage of the stems not bearing flowers is more closely set. The habit of the plant is procumbent; stems contorted, and producing solitary flowers.

It should be grown on rockwork, where its stems can nestle between the stones and its roots find plenty of moisture, as in a dip or hollowed part; the long and fleshy roots love to run in damp leaf mould and sand. The position should be open and sunny, in order to have flowers. Cuttings may be taken during summer, and struck in sandy peat kept moist, or strong roots may be divided. The latter method is the less desirable, not only because of jeopardising the parent stock but also because strong roots show to greater advantage when not separated.

Flowering period, September and October.

Cypripedium Calceolus.

ENGLISH LADY'S SLIPPER; _Nat. Ord._ ORCHIDACEÆ.

This well-known terrestrial orchid is a rare British plant, very beautiful, and much admired, so much so, indeed, that many desire to grow it. It happens, however, that it seldom thrives under cultural treatment, and seems to prefer a home of its own selection, but its habitats are said now to be very few in Great Britain, it having been hunted out and grubbed up everywhere. Fortunately, it can be grown in gardens, and in good form, though rarely seen thus. To see well-grown flowers of this orchid either makes us feel more contented with our own climate or strongly reminds us of others where the most gorgeous varieties of flowers and fruit grow wild. It is large and striking, fragrant, and very beautiful; no one can see it, especially in a growing state, without being charmed by its freshness and simplicity; it also forms one of the finest specimens for the student in botany, and in every way it is a plant and flower of the highest merit (see Fig. 32). It should be in all collections of choice plants, and every amateur should persevere until he succeeds in establishing it.

Under cultivation it flowers in early May, at a height of 9in. to 12in.; the flowers are composed of a calyx of three brownish-purple sepals, which have only the appearance of two, from the fact of the lower two being joined or grown together, and even so combined they are somewhat less than the upper sepal. The division may be observed at the tips, though in some specimens it is microscopic--in the one now by me it is hardly the eighth of an inch. Two petals; these are cross-form in relation to the sepals, of the same colour, and a little longer--about 2in.--narrow, drooping, pointed, and slightly twisted when a few days old; lip, "blown out like a slipper," shorter than the sepals, compressed, richly veined, and lemon yellow. The seed organs are curious, the stigma being foot-stalked, peltate, and placed between and above the anthers. The leaves are pale green, very hairy, many-ribbed, stem-clasping, alternate, ovate, and slightly wavy; the lower ones are 5in. or 6in. long and 2in. to 3in. wide, and pointed. The root is creeping, the fibres stout, long, wiry, and bent. During spring the plant makes rapid growth, and seldom bears more than one flower; for the first time a plant produced two with me in 1882. They are sweetly scented, like the primrose.
