The most recent investigators into botanical science are not classifying plants, but they are examining into the meaning of their structure. The mere task of description and enumeration has been done, and so they have set themselves to find out why certain structures exist, and why certain habits (if we may use the word) have been formed. Why do the climbing plants climb at all? and why do some twine, and others cling? Why do the fly-catching plants cause the death of numbers of unlucky insects? Why are the stamens and pistils in plants of such various lengths and sizes? Why have some flowers a hairy fringe, and others drops of nectar in their calyces? What is the meaning of the scent of flowers, and what is the object of the night-opening flowers? The key to many of these questions is in the relationship of flowers to insects; and Charles Darwin, Sir John Lubbock, and others, have done very much to explore and then to popularize the subject. Much that is most important has thus been made known to us, but these eminent naturalists would be the first to own that there is much more still to do. The secrets of nature open out but slowly, and after long and patient wooing. It would sometimes appear too as if there might be danger, not indeed of adapting facts to theory, but of taking it too readily for granted that all facts must eventually fit into some favourite theory. This tendency may not be so apparent in the leaders as in their less cautious disciples in these scientific researches. From some of their expressions they would almost seem to imply that insects were made for the sake of fertilizing flowers. They attribute the bright colour and beauty of flowers not to the same good purpose that gives beauty elsewhere, but as if it were merely that insects may be attracted, and do their duty among the ripening pollen. They are contemptuous at the idea of a flower being intended for the selfish pleasure of man and not for its own purposes, and they point to plants of beauty that “blush unseen” where man cannot admire them, forgetting, however, that man has seen them, or he would not know of their existence. They will learn nothing of the affluence of nature, and nothing is quite accepted unless its use can be established, though on this principle it is hard to explain why, as Bishop Hall pointed out long ago, “there is many a rich stone laid up in the bowels of the earth, many a faire pearle laid up in the bosome of the sea, that never was seen, nor never shall be.”
It is curious how apparent extremes will meet. The very men who would most readily throw over the old theological argument of “design,” which believed that everything was done in the most perfect way for the most perfect ends, will now in the interests of evolution show the necessity for each curve of a flower-cup and for each marking on a petal. We cannot be too thankful to them, if only they will make their ground sure at every step; but it will not do to generalize too rapidly. For instance, it has been stated that veins on a flower are probably guides to lead insects down into the honey-cup below, and that night-blowing flowers are without them because at night they would be invisible and useless. Unfortunately, it has since been shown that the Œnothera taraxicifolia, and probably other night-flowers, are deeply marked with veins. Again, why in some cherry-blossoms is the pistil longer than the stamens, so that the fertilization must be effected differently to what it is in the more ordinary varieties, where the stamens and pistil are of equal length? Why have blossoms gradually developed properties to attract insects, when it is obvious that those properties were not originally required for the perpetuation of the species? Why should some flowers of magnificent size, like the magnolia, require scent to attract insects, if we must indeed admit that use and not pleasure is the end and aim of every attraction of the garden? And if scent is necessary in this case, why is it not so where the flower is small and insignificant? Why among roses has La France a delicious perfume, and Baroness Rothschild none?
But such questionings are inevitable as yet: meanwhile facts are accumulating, and the whole truth, thanks to the patient and laborious workers of our time, may one day be known.
But quite apart from scientific interests, a real old garden, unaltered and unspoiled, has a peculiar interest of its own. It is sure to be haunted by associations, and nothing calls up associations so quickly and certainly as a sudden scent of flowers coming and going upon the summer air. Time and change may have been busy since some long-absent member of the family has revisited his old home, but the flowers and their fragrance, still the same as ever, will call up all the past. There is the corner where the first violets were always found; there is the rosebush from which a flower may once have been gathered of which the poor faded petals still remain; there is the lavender, which supplied the oaken presses where the house-linen was always kept. And, apart from all such fond and foolish private memories, there are all the associations with which literature has consecrated the old garden-flowers. Pelargoniums, calceolarias, verbenas, and the rest of the new-comers have but few friends, but not an old flower but is “loaded with a thought,” as Emerson says of the asters on the slopes at Concord. Roses, lilies, violets, primroses, and daffodils, have been written about over and over again, and the words of great poets rise unbidden to the memory at sight of them. And then certain flowers will recall an entire scene, and Marguerite asks her fate from the large white daisy whose name she bears, or Corisande, in her garden of every perfume, gathers—but not for herself—her choicest rose.
While a garden owes so much to the poet’s pen, it is strange that it should owe comparatively little to the artist’s brush. Who can recall a single picture of gardens or of flowers that ever gave him any great amount of pleasure! Is Watteau an exception? But it is the figures in the foreground, not the garden, for which one really cares. And of flower-painters, there are Van Huysum and the Dutchmen, with their piles and masses of blossom, of large size, but generally of dull colour, and without light or warmth about them. Then there are our English flower-painters; with some the flowers are only subsidiary to the picture, and they seem to have adopted Gilpin’s advice that
“By a nice representation of such trifles, he [the painter] would be esteemed puerile and pedantic. Fern-leaves perhaps, or dock, if his piece be large, he might condescend to imitate; but if he wanted a few touches of red or blue or yellow, to enliven and enrich any particular spot on his foreground, instead of aiming at the exact representation of any natural plant, he will more judiciously give the tint he wants in a few random general touches of something like nature, and leave the spectator, if he please, to find out a resemblance. Botanical precision may please us in the flowerpieces of Van Huysum, but it would be paltry and affected in the landscapes of Claude or Salvator.”
But even when the flower or plant is something better than a “touch” of colour, there is often some gross carelessness, or ignorance, which gives a sense of annoyance rather than of pleasure. Each returning year, the Gardeners’ Chronicle reviews the Royal Academy from a botanical point of view, and nothing can be droller than the blunders it points out. Sometimes all sorts of flowers of various seasons are growing together, or a wood, through which a knight is riding, is adorned with agarics and fungi that belong to different periods of the year. Sometimes places, no less than times, are set at nought, as in an instance quoted by Mr. Rossetti from the Exhibition of 1868, where a Greek maiden is gathering blossoms from a pot of (American) azaleas. But, indeed, such instances are only too common. In how many modern classical pictures, for example, has not the large sunflower of America been introduced? But when the flower itself is one important part of the picture, how curiously unsatisfactory is too often the result! No one has tried more earnestly to set our painters right in these matters than Mr. Ruskin, and how little even now have they profited by his teaching! They catch hold of a suggestion, as when he once told them (showed them, we might say) that a spray of pink apple-blossom against a blue sky was beautiful, and the next exhibition or two abounded in blossoming apple-boughs: but they seem unable to grasp a principle. It was in 1851, in his tract on “Pre-Raphaelitism,” that he urged the painting of “the heather as it grows, and the foxglove and the harebell as they nestle in the clefts of the rocks;” and this last year, while speaking of the same artist, Mr. Hunt, he has had to repeat the same lesson, that plants that grow are pleasanter objects than flowers that are gathered. And, indeed, the reason is not far to seek. A bunch of garden-roses thrown carelessly down upon a mossy bank—and there is scarcely an exhibition without one—not only gives one a feeling of incongruity (as though the fashionable flowers were out at a picnic), but a stronger feeling still of coming death. We know those roses must wither and die, almost, we fancy, as we look upon them. No dew that falls can now keep them alive, as it will the humble moss—so much better than they—on which they rest. And it is almost worse when the poor gathered flowers are brought indoors and placed in some blue jar or Salviati vase, and the artist shows how carefully he can draw, not so much the petals of the flowers as the texture of the porcelain or the iridescence of the glass. It is difficult enough worthily to paint the light and glow of colour in any beautiful flower, but, if it is to be painted, let it be when the plant is still growing, and as it grows. Any garden will give subjects enough, if they are only sought for. Here is a bank of daffodils; here the white narcissus and the red anemone have formed a group; here a blue forget-me-not looks up into the bell of the snake’s-head fritillary; here is a great peony bowed down with its crimson globes; here a nasturtium trails its bright yellow blossoms along a bit of grey old rock; here a cluster of hollyhocks keep watch by a garden walk; here the purple clematis clings to the orchard hedge. Pictures of flowers such as these, if only the artist have some sense of colour and some refinement of taste, would give a real and almost a new pleasure to us all.
But there must be no artistic grouping, or representing of things as they should be rather than as they are. The work must be conscientious, as in the case of a great living sculptor who, having to carve an ivy plant upon a tablet, went himself to study the form of growing ivy, and found how entirely different it is from the conventional wreaths of the ordinary marble-mason.
