Plant culture

“ Likewise those branches of plant culture which gave the first impulse toward the establishment of plant physiology have in turn been richly repaid for all the suggestions and usable facts which they furnished. Agriculture, forestry, and horticulture are to-day permeated by the spirit of plant physiology, and what these practical studies have gained in scientific insight is for the most part due to plant physiology. ”

“ And yet cultivation is on an entirely different scale, a mere pot of earth taking the place of barrowsful under out-of-door culture. In the garden I simply place a plant at the requisite depth and in the proper exposure and soil; in the greenhouse a finer discrimination is called for. ”

“ He claimed correctly that all our best fruits were artificial products, because the essential elements for the preservation of the species in their natural condition, are vigor of the plant and perfect seeds for the perpetuation of the race. It has been the [41] object of culture to diminish the extreme vigor of the tree so as to produce early fruitage, and at the same time to enlarge and to refine the pulpy portion of the fruit. He claimed, as a principle, that our plants of culture had always a tendency to run back toward the original or wild type, when they were grown from seeds. ”

“ The culture is quite simple—plenty of rich soil, a high temperature, and abundance of moisture. I have seen the plant fruit well in what is called an “intermediate house,” but, where convenient, it is much better to place it in a warm stove. Wherever rockwork or any picturesque arrangement is attempted in any of these structures; no nobler plant can be selected for its embellishment. It crawls over such positions with a snake-like stem, and a trail of great leathery leaves perforated in many places, as shown in the plate. ”

“ Arthur to suggest to others that they keep a lookout for plants that may become desirable garden varieties and try them. "It is evident that showiness in the wild state is not the most important criterion by which to gauge the future culture value of a plant. ”

“ From remote ages man has endeavored, by careful culture, to produce larger, tenderer, and sweeter varieties. Of an adaptable character, under careful treatment the plant has evolved in a docile fashion, and has ended by giving us what the ambition of the gardener desired. To-day we have gone far beyond the yield of the Varrons and Columelles, and further still beyond the original pea ”

“ The reason for this difference in reaction between native and culture formations seems evident. In harvesting, not merely the grain, but the stems and leaves, and in gardening often the root also, are removed, so that the plant makes little or no return to the soil. In nature, annual plants return to the ground every year all the solid matter of roots, stems, leaves, and fruits, with the exception of the relatively small number of seeds that germinate. ”

“ Before we trespass on the domains of arboriculture, horticulture, or agriculture, under which heads the cultivation of useful or ornamental plants divides itself, some consideration is required of those plants which, quasi-wild, are usually included in accounts of the vegetation under the head of aliens, denizens, colonists, and so forth. ”

“ The very great modifications which cultivated plants are constantly undergoing under our eyes, and the numerous varieties and races which spring up among them, certainly countenance the doctrine, that every domesticated vegetable, however dependent upon human care for growth and propagation in its present form, may have been really derived, by a long Succession of changes, from some wild plant not now perhaps much resembling it. ”

“ Subtropical gardening has shown us that one of the greatest mistakes ever made in the flower-garden was the adoption of a few varieties of plants for culture on a vast scale, to the exclusion of interest and variety, and, too often, of beauty or taste. ”

“ If I were asked to sum up the most important result of the numerous advances made during the past decade in agriculture and forestry, I should reply—the clearer and wider recognition of the fact that the plant itself is the centre of the subject, and not the soil, climate, season, or other factors of its environment. Until comparatively recent times it was the habit of farmers, foresters, planters, and gardeners, all the world over, to look upon the plant as a mere item or as a mysterious if important one in their calculations, and to regard the soil as the chief factor in their studies. ”

“ Are we not all wrong in adopting one degree, so to say, of plant life as the only fitting one to lay before the house? Is it well to devote the flower-bed to one type of vegetation only—low herbaceous vegetation—be that hardy or tender?... We have been so long accustomed to leave flower-beds raw, and to put a number of plants out every year, forming flat surfaces of colour, that no one even thinks of the higher and better way of filling them. ”

“ So the inexorable and relentless processes of nature work over the materials found in these plant communities, the results of which are the dominant types of vegetation in the world to-day. With this understanding of the part they play in plant distribution we may now consider a few of the most widely recognized plant societies and see how they have affected the vegetation, sometimes even the history of the regions in which they are found. ”

“ So far from being uniform, and unmarked by anything active, the lives of plants are full from beginning to end of the most curious and diversified phenomena. Not that they act knowingly, exercising consciousness and volition,—this has been the dream only of a few enthusiasts,—but taking one plant with another, the history of vegetable life is quite a romance, and scarcely inferior in wonderful circumstance to that of animals. ”

“ There are several species hardy and well suited for flower-garden purposes, and, more advantageous still, distinct from each other. The effect afforded by them, when well developed, is equal to that of any hothouse plant that we can venture in the open air for the summer, while they are green and ornamental at all seasons. ”

“ These æsthetic devices, or those of necessity, are advancing so rapidly that each generation sees hundreds of new animal and plant species added to our living collections, so that our plant and animal gardens now contain a large share of the more attractive forms which are to be found in the various geographical realms. Our tilled fields yield perhaps a [8] hundred times as many varieties of plants as they did in the earliest historic agriculture. ”

“ It deserves as much attention as any plant in cultivation, and yet how rarely is any thorough preparation made for its perfect development. What is there growing in garden or in wild more nobly distinct and beautiful than the great silvery plumes of this plant waving in the autumnal gusts—the burial plumes as it were of our summer too early dead? What tender plant so effective as this in giving a new aspect of vegetation to our gardens, if it be tastefully placed and well grown? ”

“ Though our country’s vegetation has lost in scientific interest, it has gained vastly in both economic and æsthetic value by the introduction of useful and ornamental plants from all the Temperate regions of the world; and besides, a large number of species have followed in man’s footsteps, and, taking advantage of the disturbance of the native flora caused by his operations, endeavour with more or less success to establish a footing in the country. ”

“ Because, by the use of the most elaborate horticulture we can occasionally cause a plant of the most delicate species to mature its fruit, shall we venture to regard the palm-tree as acclimated in our country? ”

“ In the same manner the apparatus of green leaves and long roots were found inconvenient for the more animated and sensitive parts of vegetable-flowers, I mean the anthers and stigmas, which are therefore separate beings, endued with the passion and power of reproduction, with lungs of their own, and fed with honey, a food ready prepared by the long roots and green leaves of the plant, and presented to their absorbent mouths.
From this outline a philosopher may catch a glimpse of the general economy of nature ”

“ Horticulture, apart from the mechanical details connected with the maintenance of a garden and its appurtenances, may be considered as the application of the principles of plant physiology to the cultivation of plants from all parts of the globe, and from various altitudes, soils and situations. The lessons derived from the abstract principles enunciated by the physiologist, the chemist and the physicist require, however, to be modified to suit the special circumstances of plants under cultivation. ”

“ On the other hand, some scientists are acquainted with botany and learned in horticulture. They know every plant and its value, but they care little about tidiness. Cut flowers are feminine frivolities in their eyes, and they count nosegays as childish gauds, like daisy chains and cowslip balls. They are not curious in colors, and do not know which flowers are fragrant and which are scentless. For them every garden is a botanical garden. ”

“ With a knowledge of the laws that govern these forces, the gardener will take a plant of any genus, species, or variety, from mountain or valley, from rocks or alluvion, from torrid or temperate zone, and by artificial means create a climate for its reproduction. ”

“ Living mostly by the chase and on a few wild fruits picked from the forest these half-wild and savage people wandered wherever game was plentiful and the continental glacier would permit. But there came a day when one of these races began the cultivation of some of the wild plants about them and with that day dawned the real beginning of man’s use of plants. And with that day also these simplest of our ancestors stopped their wanderings in large part and became farmers, albeit very crude ones, as their primitive stone implements show. ”

“ There are many fruits which could be grown this way that people do not usually give space to, and this applies to the varieties of cultivated fruits, as well as species that are never cultivated. The natural order to which most of our fruit trees belong contains many other species, not without merit as fruits, scattered throughout the temperate regions of the northern world. These trees and shrubs happen also to be most beautiful of flowering trees and shrubs in spring, and are well worthy of culture on that account alone. ”

“ Let 570 any one tell me in what country a similar plant grows wild, unless where it has escaped from cultivated fields? Where do we find in nature our cabbages, lettuces, and other culinary vegetables, in the state in which they appear in our gardens? ”

“ All these grow wild, and are used exactly in their natural state, unless burning the leaves of one plant in dry seasons to improve the root, or similar trifling pains respecting their growth, can deserve the name of cultivation. ”

“ The plant kingdom has become almost as clay in the hands of the potter. Where we now have one good crop plant, we may some day have five or ten. We need to start in earnest to apply some of our science to producing genius trees—trees that are to other trees as human geniuses are to other men. ”

“ God gives the seed a body "as it hath pleased Him, and to every seed its own body."
It is true that what are called "varieties" can be produced among cultivated plants, as among birds and animals, by change of food and climate, and by care and training. The same plant will soon look very different if taken from a dry, sunny spot, and placed in a damp, shady corner. I have heard that if plants are moved from their home on the seashore, and placed in a dry, hot place, their thick, fleshy leaves will in time quite change their character, becoming thin and hairy. ”

“ With this idea well fixed in your mind, you will easily see that when you know the country from which a plant has come, a knowledge of the physical geography of that country will be helpful in knowing how to make the plant happy and prosperous.
We must also make the plant comfortable in the soil. There is great difference in what plants require to make them comfortable. Some, like thistles or mullein or ragweed, will thrive on almost any soil and are no more exacting as to food than a goat or a mule; but other plants are as notional as children reared in the lap of luxury. ”

“ As most of the plants on which I experimented were grown in my garden or in pots under glass, a few words must be added on the conditions to which they were exposed, as well as on the effects of cultivation. When a species is first brought under culture, it may or may not be subjected to a change of climate, but it is always grown in ground broken up, and more or less manured; it is also saved from competition with other plants. ”

“ And again, bethink you, good, easy-going human being, how great are the difficulties she has to contend with, especially in the case of the plant creation. Put yourself in the orchid’s place, and you will see the reason. For remember how absolutely fixed and limited are plants, each rooted to the soil in a single small spot, each tied by strict conditions of rock, and water-supply, and air, and wind, and sun, and climate, from which none can escape, try they all their hardest. ”

“ But man does not really produce them. Such peculiarities—often surprising enough—now and then originate, we know not how (the plant sports, as the gardeners say) ; they are only preserved, propagated, and generally further developed, by the cultivator's skilful care. If left alone, they are likely to dwindle and perish, or else revert to the original form of the species. Vegetable races are commonly annuals, which can be kept up only by seed, or herbs of which a succession of generations can be had every year or two, and so the education by selection be completed without great lapse of time. ”
