Water–plants of northern and temperate25 regions, associated with those of our own country, add much beauty to a garden if well selected and well grown. A great deal of variety may be added to the margins26, and here and there to the surface, of ornamental27 water, by the use of a good collection of hardy aquatics28 arranged with taste; but this has not yet been fairly attempted. Usually we see the same monotonous29 vegetation all round the margin if the soil be rich; in some cases, where the bottom is of gravel30, there is little or no vegetation, but an unbroken ugly line of washed earth between wind and water. In others, water–plants accumulate till they are only an eyesore—not submerged plants like Anacharis, but such as the Water Lilies when matted together. A well–developed plant or group of plants of the queenly Water Lily, with its large leaves and noble flowers, is an object not surpassed by any other in our gardens; but when it increases and runs over the whole of a piece of water—thickening together and being in consequence weakened—and water–fowl cannot make their way through it, then even this plant loses its charms. No garden water, however, should be without a few fine plants or groups of the Water Lily. Where the bottom does not allow of the free development of the plant, earth might be accumulated in the spot where it was desired to encourage the growth of the Nymphæa. Thus arranged it would not spread too much. But it is not difficult to prevent the plant from spreading; indeed I have known isolated31 plants, and groups of it, remain of almost the same size for years. The Yellow Water Lily, Nuphar lutea, though not so beautiful as the preceding, is well worthy32 of a place; and also the little N. pumila, a variety or sub–species found in the lakes of the north of Scotland.
Then there is the fine and large N. advena, a native of America, which pushes its leaves boldly above the water, and is very vigorous in habit. It is very plentiful33 in the Manchester Botanic Garden, and will be found to some extent in most gardens of the same kind. The American White Water Lily (Nymphæa odorata) is a noble species, which would prove quite hardy in Britain. It is a pity this noble aquatic plant is not more frequently seen, as it is quite as fine as our own Water Lily. Rose–coloured varieties are spoken of, but are not yet in cultivation34 here.
One of the prettiest effects I have ever observed was afforded by a sheet of Villarsia nymphæoides belting round the margin of a lake near a woody recess35, and before it, more towards the deep water, a group of Water Lilies. The Villarsia is a charming little water–plant, with its Nymphæa–like leaves and numerous golden–yellow flowers, which furnish a beautiful effect on fine days, under a bright sun. It is not very commonly distributed as a native plant, though, where found, generally very plentiful.
Not rare—growing, in fact, in nearly all districts of Britain—but beautiful and singular, is the Buckbean or[72] Marsh36 Trefoil (Menyanthes trifoliata), with its flowers deeply fringed on the inside with white filaments37, and the round unopened buds blushing on the top with a rosy38 red like that of an Apple–blossom. It will grow in a bog or any moist place, or by the margin of any water. For grace, no water–plant can well surpass Equisetum Telmateia, which, in deep soil, in shady and sheltered places near water, often grows several feet high, the long, close–set, slender branches depending from each whorl in a singularly graceful39 manner. It will grow on the margins of lakes and streams, especially among water–side bushes, or in boggy spots in the shade.
For a bold and picturesque40 plant on the margin of water, nothing equals the great Water Dock (Rumex Hydrolapathum), which is rather generally dispersed41 over the British Isles42; it has leaves quite sub–tropical in aspect and size, becoming of a lurid43 red in the autumn. It forms a grand mass of foliage44 on rich muddy banks, and, unlike many water–plants, has the good quality of not spreading too much. The Cat’s–tail (Typha) must not be omitted, but it should not be allowed too much liberty. The narrow–leaved one (T. angustifolia) is more graceful than the common one (T. latifolia). Carex pendula is excellent for the margins of water, its elegant drooping45 spikes46 being quite distinct in their way. It is rather common in England, more so than Carex pseudocyperus, which grows well in a foot or two of water or on the margin of a muddy pond. Carex paniculata forms a strong and thick stem, sometimes 3 ft. or 4 ft. high, somewhat like a tree Fern, and with luxuriant masses of drooping leaves, and on that account is transferred to moist places in gardens, and cultivated by some, though generally these large specimens[73] are difficult to remove and soon perish. Scirpus lacustris (the Bulrush) is too distinct a plant to be omitted, as its stems, sometimes attaining47 a height of more than 7 ft. and even 8 ft., look very imposing48; and Cyperus longus is also a desirable plant, reminding one of the aspect of the Papyrus49 when in flower. It is found in some of the southern counties of England. Poa aquatica might also be used. Cladium Mariscus is another distinct and rather scarce British aquatic which is worth a place.
If one chose to enumerate50 the plants that grow in British and European waters, a very long list might be made, but those which possess no distinct character or no beauty of flower would be useless, for it is only by a judicious51 selection of the very best kinds that gardening of this description can give satisfaction; therefore, omitting a host of inconspicuous water–weeds, we will endeavour to indicate others of real worth for our present purpose.
Those who have seen the flowering Rush (Butomus umbellatus) in blossom, are not likely to omit it from a collection of water–plants, as it is conspicuous52 and distinct. It is a native of the greater part of Europe and Russian Asia, and is dispersed[74] over the central and southern parts of England and Ireland. Plant it not far from the margin, and it likes rich muddy soil. The common Arrow Head (Sagittaria), very frequent in England and Ireland, but not in Scotland, might be associated with this; but there is a very much finer double exotic kind, which is really a handsome plant, its flowers white, and resembling, but larger than, those of the old white Double Rocket. This used to be grown in abundance in the pleasure gardens at Rye House, Broxbourne, where it filled a sort of oblong basin, or wide ditch, and was very handsome in flower. It forms large egg–shaped tubers, or rather receptacles of farina, and in searching for these, ducks destroyed the plants occasionally. Calla palustris is a beautiful bog–plant, and I know nothing that produces a more pleasing effect over rich, soft, boggy ground. It will also grow by the side of water. Calla æthiopica, the well–known and beautiful Lily of the Nile, is hardy enough in some places if planted rather deep, and in nearly all it may be placed out for the summer; but, except in quiet waters, in the south of England and Ireland, it will not thrive. However, as it is a plant so generally cultivated, it may be tried without loss in favourable53 positions. Pontederia cordata is a stout20, firm–rooting, and perfectly54 hardy water–herb, with erect55 and distinct habit, and blue flowers, not difficult to obtain from botanic garden or nursery. The Sweet–flag will be associated with the Water Iris13 (I. Pseudacorus), and a number of exotic Irises will thrive in wet ground, i.e. I. sibirica, ochreleuca, graminea, and many others. Aponogeton distachyon is a native of the Cape1 of Good Hope, a singularly pretty plant, which is hardy enough for our climate, and, from its sweetness and curious beauty, a most[75] desirable plant to cultivate. It frequently succeeds in water not choked by weeds or foulness56, and wherever there are springs that tend to keep the water a little warmer than usual it seems to thrive in any part of the country. The Water Ranunculuses, which sheet over our pools in spring and early summer with such silvery beauty, are not worth an attempt at cultivation, so rambling57 are they; and the same applies to not a few other things of interest. Orontium aquaticum is a scarce and handsome aquatic for a choice collection, and as beautiful as any is the Water Violet (Hottonia palustris). It occurs most frequently in the eastern and central districts of England and Ireland. The best example of it that I have seen was on an expanse of soft mud near Lea Bridge, in Essex, where it covered the surface with a sheet of dark fresh green, and must have looked better in that position than when in water, though doubtless the place was occasionally flooded. A suitable companion for the Marsh Marigold (Caltha) and its varieties is the very large and showy Ranunculus Lingua, which grows in rich ground to a height of three feet or more.
If with this water–garden we combine the wild garden of land plants—herbaceous, trailers, etc.—some of the loveliest effects possible in gardens will be produced. The margins of lakes and streams are happily not upturned by the spade in winter; and hereabouts, just away from the water–line, almost any vigorous and really hardy flower of the thousands now in our gardens may be grown and will afterwards take care of itself. The Globe–flowers alone would form beautiful effects in such positions, and would endure as long as the Grass. Near the various Irises that love the water–side might be planted those that thrive in moist ground, and they are many, including the most beautiful kinds. Among recently introduced plants the singular Californian Saxifraga peltata is likely to prove a noble one for the water–side, its natural habitat being beside mountain watercourses, dry in the autumn when it is at rest; both flowers and foliage are effective, and the growth very vigorous when in moist ground. It would require a very long list to enumerate all the plants that would grow near the margins of water, and apart from the aquatics proper; but enough has been said to prove that, given a strip of ground beside a stream or lake, a garden of[77] the most delightful58 kind could be formed. The juxtaposition59 of plants inhabiting different situations—water–plants, water–side plants, and land–plants thriving in moist ground—would prevent what would, in many cases, be so undesirable—a general admixture of the whole. Two distinct classes of effects could be obtained, the beauty of the flowers seen close at hand, and that of the more conspicuous kinds in the distance, or from the other side of the water of a stream or lakelet.
An interesting point in favour of the wild garden is the succession of effects which it may afford, and which are suggested by the illustrations on the next pages, both showing a succession of life on the same spot of ground. In gardens in early summer at present the whole of the portion devoted60 to flower–gardening is dug up raw as a ploughed field, just when the earth is naturally most thickly strewn with flowers. A very little consideration and observation will suffice to make it clear that a succession of effects may be secured without this violent disfigurement of our gardens in the fairest days of early summer. These are not the days for digging or planting either, and the system that necessitates61 them is pernicious in its effects on our gardens.
It is equally an enemy of all peace or rest for the gardener, who, having trenched, dug, enriched, planted, and sown, through the autumn, winter, and spring, might certainly begin to look for the fruits and flowers of his labour, when he has to face the most trying effort of all—the planting of the flower–garden in May and June with a host of flowers too tender to be committed to the earth at an earlier season.
The bog–garden is a home for the numerous children of the wild that will not thrive on our harsh, bare, and dry garden borders, but must be cushioned on moss7, and associated with their own relatives in moist peat soil. Many beautiful plants, like the Wind Gentian and Creeping Harebell, grow on our own bogs62 and marshes63, much as these are now encroached upon. But even those acquainted with the beauty of the plants of our own bogs have, as a rule, but a feeble notion of the multitude of charming plants, natives of northern and temperate countries, whose home is the open marsh or boggy wood. In our own country, we have been so long encroaching upon the bogs and wastes that some of us come to regard them as exceptional tracts64 all over the world. But when one travels in new countries in northern climes, one soon learns what a vast extent of the world’s surface was at one time covered with bogs. In North America day after day, even by the margins of the railroads, one sees the vivid blooms of the Cardinal–flower springing erect from the wet peaty hollows. Far under the shady woods stretch the black bog–pools, the ground between being so shaky that you move a few steps with difficulty. One wonders how the trees exist with their roots in such a bath. And where the forest vegetation disappears the American Pitcher–plant (Sarracenia),[79] Golden Club (Orontium), Water Arum (Calla palustris), and a host of other handsome and interesting bog–plants cover the ground for hundreds of acres, with perhaps an occasional slender bush of Laurel Magnolia (Magnolia glauca) among them. In some parts of Canada, where the painfully long and straight roads are often made through woody swamps, and where the few scattered65 and poor habitations offer little to cheer the traveller, he will, if a lover of plants, find conservatories66 of beauty in the ditches and pools of black water beside the road, fringed with the sweet–scented Buttonbush, with a profusion67 of stately ferns, and often filled with masses of the pretty Sagittarias.
Southwards and seawards, the bog–flowers become tropical in size and brilliancy, as in the splendid kinds of herbaceous Hibiscus, while far north, and west and south along the mountains, the beautiful and showy Mocassin–flower (Cypripedium spectabile) grows the queen of the peat bog. Then in California, all along the Sierras, there are a number of delicate little annual plants growing in small mountain bogs[80] long after the plains have become quite parched68, and annual vegetation has quite disappeared from them. But who shall record the beauty and interest of the flowers of the wide–spreading marsh–lands of this globe of ours, from those of the vast wet woods of America, dark and brown, and hidden from the sunbeams, to those of the breezy uplands of the high Alps, far above the woods, where the little bogs teem69 with Nature’s most brilliant flowers, joyous70 in the sun? No one worthily71; for many mountain–swamp regions are as yet as little known to us as those of the Himalaya, with their giant Primroses73 and many strange and lovely flowers. One thing, however, we may gather from our small experiences—that many plants commonly termed “alpine74,” and found on high mountains, are true bog–plants. This must be clear to anyone who has seen our pretty Bird’s–eye Primrose72 in the wet mountain–side bogs of Westmoreland, or the Bavarian Gentian in the spongy soil by alpine rivulets75, or the Gentianella (Gentiana acaulis) in the snow ooze76.
Bogs are neither found or desired in or near our gardens now–a–days, but, wherever they are, there are many handsome flowers from other countries that will thrive in them as freely as in their native wastes.
