Hardy Perennials and Old Fashioned Flowers

Flowering period, February to April.

There is a variety called D. M. album; the only difference from the typical form is implied by the name, the flowers being white. It also is in bloom at the same time as the species.

D. M. autumnale is another variety, which, however, blooms in the autumn; the flowers are red; it is a native of Europe.

These shrubs enjoy a light but moist soil of a vegetable nature, but they also thrive in a sandy loam. They may be increased by seed, or, more quickly, by grafting on stocks of spurge laurel; cuttings may be rooted, but are uncertain.

Dentaria Digitata

Toothwort; Nat. Ord. Cruciferæ

A hardy, tuberous perennial, native of Switzerland, but long cultivated in British gardens, and decidedly "old-fashioned."

Imagine a spray of pale purple wallflower, and that will give some idea of the form and colour of its flowers, which are produced on round wiry stems, nearly a foot high, in terminal racemes. The leaves, which are produced mostly in threes on a stem, have a channelled petiole, and, as the specific name denotes, are spread out like fingers, mostly of five parts; a five-cut leaf of a Christmas rose will give a fair notion of the form, but the Toothwort leaves are less, not so thick, and more herb-like than the hellebore; they are also finely, deeply, but irregularly toothed. The roots are of singular form, almost like human teeth, arranged as scales, whence the name Toothwort. Its first appearance above ground is in February, when the young growths are bent or folded like those of the anemone, and in genial seasons it will flower early in March.

It loves both a little shade and moisture. I grow it at the base of a bit of rockwork, in black or leaf mould; the aspect is south-east, but an old sun-dial screens it from the midday sun. The whole plant has a somewhat quaint appearance, but it has proved a great favourite. When the tops have died down the roots can safely be lifted, cut in lengths of one or two inches, and then replanted. It also produces seed freely, but from the easy method of increase by root division, I have not had occasion to experiment with seed.

Flowering period, March to May.

Dianthus Deltoides

Maiden Pink; Old Names, "Wild Gilloflower," "Virgin-like Pinke," "Maidenly Pinke"; Nat. Ord. Caryophyllaceæ—Silenaceæ

A British species of perennial character, never failing to bloom for a long period when it meets with a suitable home in our gardens—as in positions similar to those described for Erysimum pumilum. Seen either wild or in gardens it is much admired; it bears but simple flowers, but therein consists its beauty.

As Gerarde says, "Virgin-like Pinke is like unto the rest of the garden pinkes in stalkes, leaves, and rootes. The flowers are of a blush colour, whereof it tooke his name, which sheweth the difference from the other." It is about the most simple form of the Pink tribe. The flowers are a little over ½in. across, of a rose colour or pleasing blush. It grows nearly a foot high in some soils, but in a poor compost it is more dwarf and floriferous. The flower stems are much divided near the tops, and capable of producing a good effect from their numbers of bright flowers. The leaves are small, scarcely 1in. long, linear, lance-shaped, and of a dark green colour; they are closely arranged on decumbent stems, which sometimes are more than 1ft. long. The habit is compact, both as regards leaves, stems, and flowers.

For all such places as afford dryness at the roots this is a suitable plant as a constant bloomer of effective colour. When once it has become established it seeds freely, and the young plants may be seen in the walks for yards around the parent stock. It is one of those happy subjects that can take care of themselves, either braving its enemies or having none.

In its wild state it blooms from the sixth to the tenth month, both inclusive; but with cultural attention and during favourable winters, it has been seen in flower to the end of the year.

Flowering period, June to October.

Dianthus Hybridus

Syn. D. Multiflorus; Mule Pink; Nat. Ord. Caryophyllaceæ

Hardy and evergreen. The specific name of this variety is not at all descriptive, and it may be better to at once give its common name of Mule Pink, of which there are various colours, as bright scarlet, rose and pure white, all very double and neat flowers.

It is the double rose kind which has induced me to speak of this section of the Pink and Sweetwilliam family. I dare say many will be surprised when I state that my strongest plant of this has been in flower more than two years. Severe as the 1881 winter was, when the plant was clear of snow it was seen to have both flowers and buds—in fact, for two years it has flowered unceasingly; the other varieties are not such persistent bloomers. The genus to which these hybrids belong is very numerous, and includes Carnations, Picotees, garden and alpine Pinks and Sweetwilliams. They are all remarkable for their fresh green and glaucous foliage and handsome flowers. Some species or varieties are amongst the "old-fashioned" garden plants of Parkinson's time, and all are characterised by an exquisite perfume. The Latin name of this genus is a very happy one, meaning "divine flower," in reference to its fragrance. Nearly every form and colour of Dianthus are popular favourites, and hardly any garden is without some of them.

The Mule Pink is supposed to have been produced from D. barbatus and D. plumarius; be that as it may, the features of both are distinctly seen in it: the colour and partial form of the foliage, the form of stems, and clustered arrangement of the buds much resemble D. barbatus or Sweetwilliam; whilst the stout reflexed and pointed features of the leaves, and the general form of the small but double flowers resemble D. plumarius, or the garden Pink. To this description of D. hybridus I will only add that in both foliage and flowers there is more substance than in either of its reputed parents, and the habit of the plant is semi-trailing or procumbent, as seen in specimens three years old. It is rather more difficult to grow than the common Pink. Any position or soil will not answer; it does well on rockwork, where it can hardly suffer from damp, so much disliked by all the genus; but if thus planted, it should be where its thickly-foliaged stems cannot be turned over and wrenched by strong winds. It may be grown in borders in sandy loam; and if such borders are well drained, as they always should be for choice flowers, there will be little to fear as to its thriving. Such an excellent flower, which, moreover, is perpetually produced, deserves some extra care, though, beyond the requirements already mentioned, it will give very little trouble.

To increase it, the readiest way is to layer the shoots about midsummer, half cutting through the stems, as for Carnations; thus treated, nice plants will be formed by October, when they may be lifted and transplanted to their blooming quarters; and I may here state that a line of it, when in flower, is richly effective. A good style also is to make a bold clump by setting ten or twelve plants 9in. apart. Another mode of propagation is to take cuttings at midsummer and dibble them into boxes of leaf soil and sand. Keep them shaded and rather close for a week or more. If the boxes could be placed in a cucumber frame, the bottom heat and moisture would be a great help to them. The object to aim at should be not only to root the cuttings, but to grow them on to fair-sized plants for putting out in the autumn. To do this, when the cuttings are rooted they should be planted 6in. apart in a bed made up of well decayed manure and sand, in which it will be seen that they will make plenty of roots and become sturdy plants. The wireworm and slugs are both very fond of Pinks and Carnations. Slugs should be trapped, but the wireworm, unfortunately, has often done the mischief before we become aware of its presence, and even then it is a troublesome pest to get rid of. I find nothing more useful than stirring and digging the soil as soon as there is room to work with a spade or fork; the worm cannot endure frequent disturbance, and such operations are otherwise beneficial to the plants.

Flowering period, May to September.

Dodecatheon Jeffreyanum

Nat. Ord. Primulaceæ

This is a distinct and noble species. The older leaves are more spoon-shaped, at least a foot long, rather narrow, not toothed, of a reddish colour at the base, and the mid-rib pale green, almost straw-colour; the flower scape is also reddish, but the flowers are fewer. As a foliage plant this species is very effective.

All the Dodecatheons make a rapid growth in spring, their scapes being developed with the leaves; the genus will continue in flower for two months, after which time, however, their foliage begins to dry up. They should, therefore, be planted with other subjects of later growth and blooming, so as to avoid blank spaces. The overshading foliage of other things will do them no harm, as it will be only for a season. The position should be moist and somewhat sheltered from high winds, or the stout and tender flower stems will be snapped off. The soil should be of a vegetable character and retentive of moisture. My specimens are grown in leaf soil and loam, in a dip of small rockwork. All the kinds were planted that a large flat stone, which we had ready, would so fit to, or over, them as to secure their roots against drought. This I find a good plan with moisture-loving subjects, where suitable positions are not otherwise readily offered. Besides, the varieties so grown have a pleasing appearance, and for purposes of comparison are very handy. Their propagation is easy. The crowns may be divided either in spring or autumn, the latter being the best time, as then probably each piece will flower the following spring.

Flowering period, April to June.

Dodecatheon Meadia

Shooting Star, or American Cowslip; Nat. Ord. Primulaceæ

Fig. 34. Dodecatheon Meadia.

(One-sixth natural size.)

A distinct and pretty herbaceous perennial, very hardy and floriferous. Those who do not readily recognise it by any of the above names, may do so by the illustration (Fig. 34). It has long been grown in English gardens—nearly 150 years—its habitat being North America. Not only does it do well in this climate, but since its introduction several improved varieties of this species have been produced, which are both good and distinct. A brief notice of them will not be out of place here, but first the general description may as well be given.

The flowers much resemble the Cyclamen, but they are only about one-fourth the size; the calyx is five-parted; the corolla has five stout petals inserted in the tube of calyx; they are well reflexed and rather twisted; their colour is purplish-lilac, but at the base of the petals there is a rich blending of maroon and yellow. The seed organs are very long, compact, and pointed, giving the appearance of shooting stars. The flowers are arranged in fine clusters on a scape more than a foot high, each flower having a rather long, wiry, and gracefully bending pedicel; all of them spring from one centre. The leaves are radical, oblong, smooth, dented, and wavy, about 8in. long and nearly 3in. broad.

D. M. albiflorum I do not grow, but from what I remember of it, it differs from the above only in being less vigorous and in having white flowers.

D. M. elegans.—Shorter and broader in leaf, and roundly toothed; flower stems shorter, umbels more numerously flowered, bloom deeper in colour.

D. M. giganteum has a very large leaf, much larger than the typical form of the species, and of a pale green colour, and in all other respects it is larger, being also more than a week earlier in flower.

Flowering period, April to June.

Dondia Epipactis

Syns. Astrantia Epipactis and Hacquetia Epipactis; Nat. Ord. Umbelliferæ

This is a little gem, perhaps rather overdone with too many big names; still, this choice, hardy, herbaceous perennial is worth knowing by all its titles. Never more than 6in. high, its singular flowers are very attractive; they spring from the ground almost abruptly, are greenish-yellow and leafy in appearance—in fact, what at first sight might seem to be the petals are really but whorled bracts, which embrace the tiny umbels of flowers. Soon after the flowers the leaves begin to appear, unfolding like many of the anemones, each one springing from the root only; they also are of a peculiar colour and shape, being three-lobed and finely notched.

It will stand any amount of rough weather, always having a fresh appearance when above ground. It forms a choice specimen for pot culture in cold frames or amongst select rock plants; it should be grown in mostly vegetable mould, as peat or leaf mould, and have a moist position. Not only is it a slow-growing subject, but it is impatient of being disturbed; its propagation should therefore only be undertaken in the case of strong and healthy clumps, which are best divided before growth commences in February.

Flowering period, April and May.

Doronicum Caucasicum

Leopard's-bane; Syn. D. Orientale; Nat. Ord. Compositæ

The specific name denotes sufficiently whence this comes. It is hardy, herbaceous, and perennial, and one of those plants which deserves to be in every garden; its general appearance is that of a tender plant, from the pale but fine delicate green of its foliage, a somewhat uncommon shade for so early a season. It begins to flower in March in a warm situation in the garden, when only a few inches high, and it goes on growing and flowering until summer, when it is nearly 2ft. high. A glance at Fig. 35 will give a fair idea of its habit.

Fig. 35. Doronicum Caucasicum

(One-third natural size.)

The flowers, which are bright yellow, are 2½in. across, produced one at a time, though the leafy stems are well supplied with buds in various stages of development. The leaves, besides being so rich in colour, are of handsome forms, being variously shaped, some having long stalks, others none; all are finely toothed and heart-shaped; the radical ones come well out and form a good base, from which the flower stems rise, and they in their turn serve to display the richly veined and ample foliage which clasps them to near their tops. Although this species is not a very old plant in English gardens, it belongs to a genus, several species of which are very "old-fashioned," and, consequently, it shares the esteem in which such subjects are held at the present time.

If left alone, after being planted in fairly good soil, it will soon grow to a bold specimen. Plants three years old are 2ft. across; rockwork or ordinary borders are alike suitable for it, but if planted on the former, it should be of a bold character, so as to harmonise. I have observed that neither grubs nor slugs seem to meddle with this plant, which is certainly a rare recommendation. Its propagation may be carried out at almost any time.

Flowering period, March to July.

Echinacea Purpurea

Syn. Rudbeckia Purpurea; Purple Cone-flower; Nat. Ord. Compositæ

In the autumn season one is almost confined to Composites, but in this subject there is, at any rate, a change, as regards colour. Yellows are indispensable, but then predominate too strongly. The flower under notice is a peculiar purple with greenish-white shadings. This will doubtless sound undesirable, but when the flower is seen it can hardly fail to be appreciated. It is much admired; in fact it is stately, sombre, and richly beautiful—not only an "old-fashioned" flower, but an old inhabitant of English gardens, coming, as it did, from North America in the year 1699. In every way the plant is distinct; it does not produce many flowers, but they individually last for several weeks, and their metallic appearance is a fitting symbol of their durability. They begin to expand in the early part of September, and well-established plants will have bloom until cut off by frost.

The flowers are borne at the height of 2ft. to 3ft., and are produced singly on very thick, rigid stalks, long, nearly nude, grooved, furnished with numerous short, bristle-like hairs, and gradually thickening up to the involucrum of the flower. Said involucrum is composed of numerous small leaves, a distinguishing trait from its nearest relative genus Rudbeckia. The receptacle or main body of the flower is very bulky; the ray is fully 4in. across, the florets being short for so large a ray; they are set somewhat apart, slightly reflexed, plaited, and rolled at the edges, colour reddish-purple, paling off at the tips to a greyish-green; the disk is very large, rather flat, and furnished with spine-like scales, whence the name Echinacea, derived from echinus (a hedgehog). In smelling this flower contact should therefore be avoided; it is rather forbidding; the disk has changeable hues of red, chocolate, and green. The leaves of the root are oval, some nearly heart-shaped, unevenly toothed, having long channelled stalks; those of the stems are lance-shaped, distinctly toothed, of stouter substance, short stalked, and, like those of the root, distinctly nerved, very rough on both sides, and during September quickly changes to a dark, dull, purple colour. The habit of the plant is rather "dumpy;" being spare of foliage, thick and straight in the stems, which are drum-stick like; it is for all that a pleasing subject when in flower; I consider the blooms too stiff for cutting, more especially as they face upwards.

Unlike many species of its order, it is somewhat fickle. I have lost many plants of it; it likes neither shade nor too much moisture; latterly I have found it to do well in a sunny situation, in deep rich loam and vegetable soil mixed. If planted with other ray flowers it forms a fine contrast, and when once it has found suitable quarters the more seldom it is disturbed the better. It may be propagated by division, which may be more safely done after growth has fairly started in spring, or it may be done at the sacrifice of the flowers in late summer or early autumn, before growth or root action has ceased.

Flowering period, September to end of October.

Edraianthus Dalmaticus

Nat. Ord. Campanulaceæ

A rare and beautiful alpine species, from Dalmatia and Switzerland. At the end of July it is one of the most distinct and charming flowers in the rock garden, where it not only finds a happy home, but, by its neat and peculiar habit, proves a decorative subject of much merit. This desirable plant (see Fig. 36) is quite hardy in this climate, being herbaceous and perennial; it has, however, the reputation of being difficult to manage, but, like numerous other things, when once its requirements and enemies are found out, the former supplied and protection from the latter afforded, it proves of easy management. In some instances these conditions may, though stated in such few words, prove comprehensive; but in this case it is not so. The position and soil it most seems to enjoy may be readily afforded in any garden, as we shall shortly see; but, so far as my experience goes, the slugs are its most persistent enemies. Especially when in flower do they make long journeys to reach it; they go over sand and ashes with impunity, and often the beautiful tufts of bloom are all grazed off in one night. I had occasion to fetch in from the garden the specimen now before me, and, when brought into the gaslight, a large slug was found in the midst of the grassy foliage, and a smaller one inside one of the bell flowers. The "catch and kill 'em" process is doubtless the surest remedy, and three hours after sunset seems to be the time of their strongest muster. Not only does this plant suffer from slugs when in flower, but perhaps equally as much when in its dormant state, especially if the winter is mild; then I have noticed the somewhat prominent crowns eaten entirely off, and it is not unlikely that this plant has come to have the name of a fickle grower, from being the favourite prey of slugs.

Fig. 36. Edraianthus Dalmaticus.

(One-half natural size.)

It is not more than 4in. high under any conditions in this climate, and more often only 3in. in height. From the thrift-like tufts of foliage there radiates a set of stout round flower stalks, which are 3in. to 4in. long, and rest on the ground; the large heads of flowers are erect; the stalks are red, and furnished with short stout hairs and short foliage, the latter becoming sere long before the bloom fades. The crowded heads of "bells" are of pale purple colour, in the style of the bell-flower; they are an inch in length, the corolla being somewhat deeply divided; eight to twelve form the terminal cluster, and they have a fleshy calyx, with very long and persistent segments; the lower part can scarcely be seen for the ample and somewhat peculiar bract which closely embraces the whole cluster; said bract springs from the much thickened stalk and is composed of half leaf and half scale-like forms, arranged in two or more circles; the scales feather off with the leaf-like appendage, the latter being reflexed, but the whole is furnished with spines. The foliage of a well-grown specimen is arranged in tufts, the whole having a grass-like appearance. The leaves are 2in. to 4in. long, rough and hairy on the upper side, smooth and shining underneath, the edges having rather long hairs their whole length; the main root is long, thick, and somewhat woody.

To grow this plant well, it requires a good deep loam for its long roots, and a surfacing of grit will be of benefit, as the crowns should be clear of the damp loam. This elevation of the crowns is natural to the plant, and should be provided for. The position cannot well be too exposed, provided the deep searching roots can find plenty of moisture. On rockwork this subject may be planted with considerable effect. If put between large stones in upright positions, the plant will show its pretty form to advantage. The spoke-like flower stalks, radiating from the rich dark green tufts of foliage, are very pleasing. It may be propagated by offsets from strong and healthy plants. Care should be taken not only to have all the roots possible with each crown, but the young stock should be carefully established in pots before planting in the open. Shade and careful watering will be needful; too much of the latter will render rot inevitable. Soon as the flowering period is past is the best time to divide the roots, which should not be done too severely.

Flowering period, July and August.

Epigæa Repens

Creeping or Ground Laurel; Nat. Ord. Ericaceæ

A hardy evergreen creeper, long since imported into this country from North America (1736), but only within the last few years has it won much favour. At the present time it is much sought after. It has the reputation of being a ticklish subject to grow. Many have had it and lost it, and those who still retain a specimen are loth to mutilate it for increase. This may to some extent account for the present demand for and difficulty experienced in obtaining it. For the last three years, hard as the seasons have been within that time, its flowers have been produced in great abundance on my specimen.

Usually it flowers in this climate in April, but when winter has continued open and genial, its blooms are produced as early as the middle of March, and they are in their full beauty in early April. They are white, delicately tinged with pink, of much substance and wax-like appearance. They are small, not unlike in form the lilac flower, but rather more open at the corolla and shorter in the tube. They are arranged in one-sided, elongated bunches, which rest on the ground, the blossoms peeping through the foliage. I must not omit to mention perhaps the most desirable property of this species—viz., the perfume of its flowers, which is strong, aromatic, and refreshing. The leaves are cordate, ovate, and entire, nearly 2in. long, slightly drawn or wrinkled, and covered with stiffish hairs. They are arranged on procumbent branches, all, like the flowers, facing upwards. To see the clusters of waxy flowers these branches must be raised, when it will be seen that the flower stalks issue from the axils of the leaves all along the branches. In a cut state the flowers are more than useful; they are, from their delicious, scent, a great treat. The plant is a suitable companion to the ledums, kalmias, gaultherias, and other genera of its own order.
