Rock garden

“ Rock gardens are of so many legitimate—in other words, natural—types, that [Pg 3] there is not the slightest excuse for a rockery. Even that commonest of excuses, finding a use for stray stones, falls to the ground. Any close observer of nature is familiar with these types. The natural rock gardens range from the patches of alpine plants above the timber line in high mountains down the lower slopes and through defiles to fields on or near sea level. ”

“ What a rock garden should be, is an integral part of the landscape, completely at home and in harmony with its surroundings, and having a sound reason for its existence. Except for a few functional affairs such as walls that retain terraces and steps that climb banks, their purpose is mainly ornamental. Neither rocks nor plants are featured at the expense of the other. Both work together to create the picture—the plants to add brightness, vitality, and life ”

“ If we think of the changes in gardening terms which have occurred during the last quarter of a century, there is surely significance in the gradual transition from the Rock Garden or Alpine Garden into the more imposing Rock Garden of our present-day language. It points to the bolder grouping—now happily adopted in most good gardens and more in accordance with Nature's pattern—which includes evergreen and flowering shrubs as well as the close-growing alpine plants, gem-like in their brilliant colours, which in earlier days were alone considered suitable for the purpose. ”

“ The drip is bad, especially for alpines, and the greedy roots not only rob the plants of nourishment but are very apt to dislocate the stones.
Wherever possible make the entrance to the rock garden a rough flight of steps. Excavate if necessary. Plant the step crevices as well as those of the side walls
Somewhere just outside the real garden is the best place; then it is only a step from one little world into another that is altogether different. If the rock garden leads to a bit of wood, either directly or through a wild garden, there will be all the more to rejoice over. ”

“ The advantages of a rock garden are, primarily, an element of picturesqueness that nothing else can provide, and the possession of a place in which can be grown some of the loveliest flowers on earth that, if they flourish at all, will never do as well in the ordinary garden as in conditions more or less approximating their natural habitat. ”

“ The bog, too, the heath and the desert, they take unto themselves, though perhaps only the nearer edge. And does man, by ponderous effort, raise up massive masonry in orderly fashion; one day disorder comes and nature makes things look natural by another kind of rock garden. ”

“ Here, in a nutshell, are not only the natural variations of the rock garden, but the inspiration. No rock garden worthy of the name has ever been created by man that did not depend upon a study of those that nature has given the world in prodigal abundance. ”

“ The mountain slope on which we live must have always been beautiful of itself; but for all that, our garden—that is to say, the space about our landlord's house and our own—has been treated with extreme care. Our inclosure is framed towards the great temple groves, and the great mountains behind them, by a high wall of rock, over which, at a corner edged with moss, rolls a torrent, making a waterfall that breaks three times. The pool below, edged with iris that grow in the garden sand, is crossed by a bridge of three big flat stones, and empties secretly away. ”

“ Nor should the rock garden, any more than the rockery, be in the lawn unless it is depressed and therefore out of sight, or mainly so, from the level. The depression may be a natural or an artificial one, it may be a brook with high banks or it may be a sunken pathway. The edge of a lawn is better, a corner of it is better yet, and preferable to either is a bank sloping down from it. ”

“ I always tremble for the lowlander who, down in the depth of his nature, has a prenatal hankering for rocks, [Pg 5] because he is apt to build an undigested rockery! These sort of rockeries are wholly separate from the rock gardens, often majestic, that nowadays supplement a bit of natural rocky woodland, bringing it within the garden pale. The awful rockery of the flat garden is like unto a nest of prehistoric eggs that have been turned to stone, from the interstices of which a few wan vines and ferns protrude somewhat, suggesting the garnishing for an omelet. ”

“ The easy rock garden plants, where the material is not taken from the wild, are to be found in most of the large hardy gardens of the East. Some of them are natives of Europe or Asia, and more than is commonly suspected are at home in other parts of the United States. ”

“ Spring is the best time to make a rock garden. When the important matter of the proper site has been put in the past, a definite scheme must be planned. Upon the definiteness of this scheme, much of the success of the rock garden will depend. Here desire will have to be subservient to the situation. It is not so much what you want as what is best in the circumstances.
Do not attempt slavishly to copy the rock garden of some one else. All the money in the world would not create an exact duplicate for you, since nature has made no two rocks precisely alike. ”

“ Neither the water nor the bog garden is dependent on rocks. Either or both, however, may just as well be an adjunct of the rock garden. They solve the wet spot problem admirably, permit the culture of native water lilies, orchids, and numerous other beautiful plants, and certainly contribute their share of picturesqueness. If water is lacking, it may often be introduced at little expense. ”

“ And they are so many; more than most [Pg 34] realize, and often of an individual beauty not always appreciated in the bewildering profusion of the wild but plainly apparent when an individual, or a little group, is open to close study in a rock garden. Do not make the rather common mistake of thinking that they are too familiar to be interesting; they are never likely to be. And, honestly, can you say in your heart that they are?
Native plants are excellent material for the rock garden. ”

“ There are two ways of planting a rock garden. One is to do all the crevice planting along with the building, and the other, of course, is to defer everything until the rocks are in place and the soil thoroughly settled.
The former plan is a singularly appealing, as well as practical, one. There is something fascinating in finishing completely a part of the work as one goes along. The practical advantage lies chiefly in the fact that by this method good-sized plants may be firmly established in crevices at the very outset. ”

“ From ferns alone, or from only plants of shrubby growth, a most beautiful native rock garden may be made. And adding small flowering plants, or excluding all else, there are limitless opportunities. It goes without saying that A's rock garden in Maine will not be like B's in Louisiana ”

“ Anywhere there is abundant opportunity. Take a leaf or two from the book of the Japanese gardeners. They are past-masters of the art of making rock gardens, with a bit of water thrown in. They make use of comparatively few blossoming plants, but their example is invaluable in the disposition of rocks with simple effectiveness, in the simulation of height and distance, in the proper employment of turf, and in the planting of such small trees and shrubs as are suitable for a rock garden scheme. ”

“ PLANTS FOR A ROCK GARDEN
So many plants are suitable for a rock garden that the range of choice is bewildering. In this, as in the laying out of the garden, advisability takes precedence over pure personal desire, though, very fortunately, it is often not difficult to make the two go hand in hand; a little intelligent thought helps a lot. ”

“ Occasionally—and here is one of the most important things to be learned about the rock garden—it is the veritable key to the garden situation; there are small places where no other kind is worth while, if indeed it is possible. ”

“ Any other kind of a garden would have been out of place and taste there. Wherever a rocky ledge is found, there is a possibility for a rock garden.
"To have a good garden of this sort, one must have earth as well as rocks. Earth must be put into all the crevices of rock, so that there is some depth to it, and at such an angle that it won't be washed out by hard rains. A rock garden should have an earth foundation. I mean that there must be much of earth about it. I saw a charming one, which had only climbing nasturtiums planted over it. ”

“ Mere surface watering is bad enough in the ordinary garden; in a rock garden it is a fatal error, as the growth of roots near the top of the soil [Pg 31] leaves the plants in no condition to stand the full force of the summer sun.
Go over the garden thoroughly once a year and all the time keep a sharp lookout for weeds. If the soil is heavy, top-dress with grit in the fall. Grit is good for rock plants. Stone chips placed around a plant will prevent too much dampness lodging about the collar in winter. ”

“ Like most hobbies, rock-gardening provides an endless topic of interest for its devotees, and the lore of the subject is inexhaustible. At any rate, Mr. Reginald Farrer, who is a recognized authority on the art, by no means exhausted his stock of information and anecdote in his previous work, 'My Rock-Garden.' That garden, as most of his fellow-enthusiasts know, is on the slopes of Ingleborough in Yorkshire, and it is a place of pilgrimage for the faithful of this cult. ”

“ Scarcely less important is the choice of a site, for if the rock-garden is placed under the drip of trees it is hopeless to expect that any of the more delicate and beautiful Alpine plants can thrive. ”

“ The bog garden simply reproduces bog conditions. As a rock garden adjunct it may be a small spot with the perpetually moist and moss-covered soil in which the native cypripediums and pitcher plants flourish. Eighteen or twenty inches of suitable soil, a mixture of leaf mold, peat, and loam, in which has been stirred some sand and gravel, must be provided. If an artificial bog, the bottom may be made of cement or puddled clay. ”

“ These pockets are of prime importance in the construction of a rock garden. They hold the only considerable spaces of soil and are the chief means of colonizing plants, thus providing for pronounced color effects. They should break the slopes and be irregular in size, shape, and distribution. The large ones may be easily subdivided by small stones when the planting is done if a further separation of species is desirable. The soil must slope a little from the top, so that there will be no standing water. ”

“ The height is entirely arbitrary, but some points should be at least as high as the line of vision, as one of the great advantages of a rock garden is the pleasure of enjoying some of the typical rock plants without stooping. The rocks used as fillers should overlap here and there to give strength, but care must be taken to contrive plenty of long soil runs. Eighteen inches should be the very least. ”

“ Above the house the ground rises another step, and the boundary of the garden here is a wall of native rock, which is already half veiled with the trees and trailing plants interposed to relieve its ruggedness. ”

“ So far as plants native to the immediate neighborhood are concerned, their value to the rock garden of the average person with limited time, who is not obsessed with the idea of growing the rare and curious, cannot be overestimated. ”

“ A wall garden is a perpendicular rock garden. But whereas a rock garden is of all things irregular, a wall garden has regularity. The wall need not be a straight line; it is better that one end should describe a curve, and rocks at the base may give it further irregularity. Yet it can never quite lose the air of man's handiwork. ”

“ Problems of insufficient rain, poor soil, and rocky ground have been overcome by most scientific measures, and now a pool filled with Lilies and bordered with water-loving [Pg 268] plants is a feature of a wonderful rock garden abundantly and tastefully planted with the perennials most suitable for rocks or for moisture. The Rose garden near by and long path leading to the house, bordered with beds of perennials, are further delightful tributes to the devoted labor of one who has spent much time on this, her gladdest task. ”

“ But if you have a place in your yard, which is near the woods or in the vicinity of trees, or by a rocky ledge—in short, if you have any place with a bit of wildness surrounding it, use this for a rockery. If your yard is just a plain, tame, civilized yard, you'd better leave the rock garden out. I know of a lady living in a city, whose backyard is a rocky ledge. ”

“ In the cavities between the stones, filled with earth, alpine or trailing plants are inserted, and also some of the choicest flowers. In proper situations, a small pool of water may be introduced for the culture of aquatic plants. In these days the rock-garden is a most important feature, and it requires a good deal of care and skill to arrange the boulders, walks, pools or streams in natural and artistic fashion. The selection of suitable alpines, perennials and shrubs and trees also necessitates considerable knowledge on the part of the gardener. ”

“ Many garden lovers delight in collecting wild flowers, digging them up in the neighboring woods to blossom in their cultivated garden. Why not give them a home by themselves in a rough rockery? This can easily be built from stones found on the estate. Here we deviate from the stilted idea of paths and introduce stone steps. These should be large and rough enough to fit in with our plan. Hardy ferns should be planted on either side and rock plants between the steps. You will then see the wisdom of creating a path like this which is in sympathy with the general idea of the garden. ”
