Chapter 9

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.

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.

Its culture, in this climate at least, has, from all accounts, proved rather difficult, so that it may be said to require special treatment; such, at any rate, has been my experience of it. Suitable soil, aspect, shelter, moisture, and position, all seem necessary for the well-doing of this plant. It deserves them all, and, let me add, they may all be easily afforded. The list of requirements may seem formidable on paper, but to put them into practice is but a trifling affair. My specimen is grown in leaf mould, a little loam mixed in with it, and fine charcoal instead of sand, but sand will answer nearly as well; the aspect is east, it is sheltered from the west by a wall, the north by rhododendrons, and the south by a tall andromeda. Moreover, its position is one that is sunken between small mounds, where moisture collects, and is never wanting; and when the specimen was first planted a large sandstone was placed over its roots to further secure them against drought; under these conditions it has thriven and flowered well, and afforded many offshoots. I attribute its well-doing mainly to the sheltered aspect and even state of moisture, but doubtless all the conditions have helped its growth. Its propagation is best carried out by earthing up about the collar, so as to induce the branches to become rooted, or they may be pegged near the extremities like carnation layers, but they will be two years, probably, before they can be safely lifted.

Flowering period, middle of March to end of April.

Eranthis Hyemalis.

_Syn._ HELLEBORUS HYEMALIS; WINTER ACONITE; _Nat. Ord._ RANUNCULACEÆ.

This, though well known and a general favourite, is not seen in the broad masses which ought to characterise its culture.

It is nearly related to the Christmas roses, and, like them, flowers in winter, the bright golden blossoms suddenly appearing during sunshine close to the earth. A little later the involucrum becomes developed, and is no unimportant feature. It forms a dark green setting for the sessile flower, and is beautifully cut, like the Aconite. There are other and very interesting traits about this little flower that will engage the study of botanists.

It enjoys a moist soil, somewhat light; also a little shade. In such quarters not only do the tubers increase quickly, but the seed germinates, and if such positions are allowed it, and garden tools kept off, there will soon be a dense carpet of golden flowers to brighten the wintry aspect of the open garden. Many things in the way of deciduous flowering shrubs may be grown with them, their bareness in winter and shade during summer favouring their enjoyment and growth. Early in the summer they die down. From that time the tubers may be lifted and transplanted. Such work should be finished in early autumn, or the roots will not have time to establish themselves for the first winter's bloom.

Flowering period, December to February.

Erica Carnea.

WINTER HEATH; _Nat. Ord._ ERICACEÆ.

A well-known, hardy, evergreen shrub, belonging to a genus comprising many hundreds of species and varieties, which, for the most part, however, are not hardy in this country, being natives of the Cape. The genus is most numerously and beautifully illustrated in _Loddige's Botanical Cabinet_. This might be thought to have no claim to consideration in this book, but I introduce it because of its great value in the spring garden, and because in all respects it may be cultivated like an ordinary border plant, which is saying a deal for one of the Heath family.

_Erica carnea_ comes to us from Germany, but it has so long been grown in this country that it would appear to have become naturalised in some parts. In the latter part of March it is to be seen in its full beauty; the flowers are reddish-purple, abundantly produced on short leafy stems, and arranged in racemes, drooping; the foliage is of the well-known Heath type; the whole shrub has a procumbent habit, rarely growing more than a foot high; its fine deep green foliage, compact habit, and bright enduring flowers are its chief recommendations; the latter often last six weeks in good form and colour, so that little more needs to be said in its praise.

It can hardly be planted in a wrong position--on rockwork, in borders, or shrubberies, fully exposed, or otherwise, it proves a cheerful object, whilst as an edging shrub it is second to none, excelling box by the additional charm of its flowers. Not long since I was struck by the way in which the common vinca had interlaced itself with a few bushes of this Heath, both being in full bloom at the same time; the effect was truly fine, the red of the Heath and pale blue flowers of the periwinkle being so numerous and set on such a fine bright green carpet, of two distinct types of foliage, that to my mind they suggested a most pleasing form of spring bedding, and also one of semi-wildness, which, for quiet beauty, more laboured planting could certainly not excel. Most Ericas require peaty soil; in the case of this, however, it is not necessary. Doubtless it would do well in peat, but I have ever found it to thrive in ordinary loam or garden soil, so that I have never planted it otherwise, except where peat has been the most handy. It is also easily propagated, carrying, as it does, plenty of root as well as earth with each rooted stem; these only need to be carefully divided and transplanted in showery weather, just before the new growths commence being the best time. An annual top dressing of leaf mould is very beneficial.

Flowering period, February to April.

Erigeron Caucasicus.

CAUCASION FLEABANE; _Nat. Ord._ COMPOSITÆ.

Herbaceous and perennial. This species is a somewhat recent introduction compared with some of the same genus which may be called old varieties, from having been introduced as early as 1633, as in the case of _E. graveolens_. Moreover, the genus is represented by such British species as _E. acris_, _E. alpinus_, and _E. uniflorus_. The variety now under notice is, as its specific name implies, a native of the Caucasus, first brought into this country about sixty years ago. It is a pleasing subject when in flower, and is certainly worth growing.

Its daisy-shaped flowers are less than an inch across, and when fully matured of a rosy purple colour; but, perhaps, the most interesting and attractive features about this plant are the various forms and colours of its flowers at their different stages of development; just before opening, the buds are like miniature birds' nests formed of white horsehairs, all arranged in the same way, _i.e._, round the bud, but the points are turned into the centre--these are the unexpanded florets; the next stage of development may be seen in buds, say, two days older, when a few of the florets have sprung from the nest form, and have the appearance of mauve-coloured spiders' legs laid over the bud; gradually they (being dense and numerous) expand in a similar manner, outgrowing their angularity, and at the same time deepening in colour, until at length we see the rosy-purple, daisy-shaped, and feathery flower with a yellowish centre. These pleasing flowers are borne in loose masses on stems nearly 2ft. high, and remain in bloom all the summer through.

About the middle of August a large plant was divided, and the flowers were then cut away. The young stock so propagated were in flower in the following June. I may here appropriately name an experiment I tried on this species two years ago. It was sent to me as the dwarf _Aster dumosus_, which it much resembles in the leaves, these being spoon-shaped from the roots, the others tongue-shaped and stem-clasping, but rougher and lighter green. I also saw it was not woody enough in the stem for the Michaelmas daisy. It was then near flowering, and the winter was just upon us, so, in order to get the flowers out, I covered it with a bell glass, slightly tilted. It flowered, and continued to flower throughout the winter with such shelter, and doubtless many of our fine late-blooming perennials, by such simple contrivances, might have their flowers protected or produced at a much later date than otherwise.

Flowering period, June to October.

Erigeron Glaucum.

_Syn._ CONYZA CHILENSIS; GLAUCOUS FLEABANE, _or_ SPIKENARD; _Nat. Ord._ COMPOSITÆ.

This very beautiful species is far from common. There are many facts in connection with it which render it of more than ordinary value and interest. It is sometimes classed as an alpine; probably that is only an inference, or it may be so considered by some, from its dwarf habit and suitable association with alpines. It is not an alpine; it comes from South America, and though that climate differs so widely from ours, the plant grows and winters to perfection in this country.

One of its main distinctions is its somewhat shrubby and evergreen character; of the whole genus, so far as it is at present comprehended, it is the only species with such traits; its foliage, too, is of leathery substance, and compares oddly with the herb-like leaves of its relatives; it is, moreover, as indicated by its specific name, of a glaucous hue; and otherwise, as may be seen in the following description, there exist well marked dissimilarities. But, what is of more importance, when viewed as a garden subject or an ornamental flower, it is one of the most useful as well as distinctly beautiful, as much from the fact that it produces its flowers in two crops, which extend over six or seven months of the year, as from their numbers and showiness.

The flowers are nearly 2in. across the ray, the florets being of a pleasing lilac-purple, and rather short, owing to the large size of the disk, which is often nearly an inch in diameter; this part of the flower is more than usually effective, as the disk florets become well developed in succession, when they have the appearance of being dusted with gold; the scales, which are set on the swollen stem, are of a substantial character; the numerous imbricate parts, which are covered with long downy hairs pointing downwards, give the body of the flower a somewhat bulky appearance. It will be observed that I have made no mention of the Conyza traits of divided ray florets and reflexed scales, simply because they do not exist in this species, and though there are other Conyza traits about the plant, notwithstanding its almost isolating distinctions from other Erigerons, it would seem to have more properly the latter name, and which is most often applied to it. The flower stems, which produce the flowers singly, seldom exceed a height of 12in.; they are stout, round, and covered with soft hairs, somewhat bent downwards. They spring from the parts having new foliage, and for a portion--about half--of their length are furnished with small leaves, which differ from those on the non-floriferous parts of the shrub, inasmuch as they have no stalks. The leaves are produced in compact tufts on the extremities of the old or woody parts of the shrub, which become procumbent in aged specimens; the leaves vary in length from 2in. to 4in. long, and are roundly spoon-shaped, also slightly and distantly toothed, but only on the upper half; they are stout, ribbed, clammy, and glaucous. The habit of the shrub is much branching, dense, and prostrate; its foliage has a pleasant, mentha-like odour, and the flowers have a honey smell.

This subject may occupy such positions as rockwork, borders of the shrubbery, or beds of "old-fashioned" flowers. Its flowers, being, as taste goes at the present time, of a desirable form, will prove very serviceable as cut bloom. A good loam suits it to perfection, and no flower will better repay a good mulching of rotten manure. Its propagation, though easy, is somewhat special, inasmuch as its woody parts are stick-like and bare of roots, until followed down to a considerable depth, therefore the better plan is either to take advantage of its prostrate habit by pegging and embedding its branches, or, as I have mostly done, take cuttings with a part of the previous season's wood to them, put them well down in deeply-dug light soil, and make them firm. If this plan is followed, it should be done during the summer, so that the cuttings will have time to root before winter sets in. The layering may be done any time, but if in spring or summer, rooted plants will be ready for the following season.

This subject begins to flower in June, and, as already hinted, it produces two crops of flowers; the first are from the parts which have been green and leafy through the winter, the second from the more numerous growths of the new season, and which are grandly in bloom in August; not only are the latter more effective as regards numbers and colour, but the fuller habit or more luxuriant condition of the shrub render the specimens more effective in late summer.

Eryngium Giganteum.

GREAT ERYNGO; _Nat. Ord._ UMBELLIFERÆ.

This hardy species was brought from the Caucasus in 1820. The genus, though not commonly patronised as garden subjects, are, nevertheless, highly ornamental, and when well grown much admired. Specimens are of various heights, according to position and nature of the soil; under ordinary conditions they will be 2ft. to 3ft. high at the blooming period.

As will be inferred from the order to which the Eryngium belongs, the flowers are aggregate, of a changeable blue, and arranged in cone-shaped heads 1½in. long; the heads are neatly embraced by an ample bract of prickly leaves; the main flower stem is well and evenly branched (see Fig. 37), each node being furnished with leaves which clasp the stems; they are, like those of the flower bract, deeply cut and prickly; the radical leaves are very different, long stalked, large heart-shaped and toothed, of good substance and a glossy green colour. The whole plant has a rather stiff appearance, the flower stems, together with the stem leaves, are of a pleasing hue, nearly the colour of blue note paper; this is characteristic of several of the genus, and adds greatly to their effect. Specimens look well with a grassy foreground or in borders.

Their culture is easy, provided the soil is of a light nature; a sunny position is needful, in order to have the tops well coloured. Propagate by division of strong and healthy clumps when dormant. Wireworm and grub are fond of the roots; when the plants appear sickly, these pests should be looked for.

Flowering period, August and September.
