Not even heat, since his collection will be "cool" naturally; if frost be excluded, that is enough. I should not have ventured to say this some few years ago—before, in fact, I had visited St. Albans. But in the cool house of that palace of enchantment with which Mr. Sander has adorned the antique borough, before the heating arrangements were quite complete though the shelves were occupied, often the glass would fall very low into the thirties. I could never learn distinctly that mischief followed, though Mr. Godseff did not like it at all. One who beheld the sight when those fields of Odontoglossum burst into bloom might well entertain a doubt whether improvement was possible. There is nothing to approach it in this lower world. I cannot forbear to indicate one picture in the grand gallery. Fancy a corridor four hundred feet long, six wide, roofed with square baskets hanging from the glass as close as they will fit. Suspend to each of these—how many hundreds or thousands has never been computed—one or more garlands of snowy flowers, a thicket overhead such as one might behold in a tropic forest, with myriads of white butterflies clustering amongst the vines. But imagination cannot bear mortal man thus far. "Upon the banks of Paradise" those "twa clerks" may have seen the like; yet, had they done so their hats would have been adorned not with "the birk," but with plumes of Odontoglossum citrosmum.
I have but another word to say. If any of the class to whom I appeal incline to let "I dare not wait upon I would," hear the experience of a bold enthusiast, as recounted by Mr. Castle in his small brochure, "Orchids." This gentleman had a fern-case outside his sitting-room window, six feet long by three wide. He ran pipes through it, warmed presumably by gas. More ambitious than I venture to recommend, "in this miniature structure," says Mr. Castle, "with liberal supplies of water, the owner succeeded in growing, in a smoky district of London"—I will not quote the amazing list of fine things, but it numbers twenty-five species, all the most delicate and beautiful of the stove kinds. If so much could be done under such circumstances, what may rightly be called difficult in the cultivation of orchids?
COOL ORCHIDS.
This is a subject which would interest every cultured reader, I believe, every householder at least, if he could be brought to understand that it lies well within the range of his practical concerns. But the public has still to be persuaded. It seems strange to the expert that delusions should prevail when orchids are so common and so much talked of; but I know by experience that the majority of people, even among those who love their garden, regard them as fantastic and mysterious creations, designed, to all seeming, for the greater glory of pedants and millionaires. I try to do my little part, as occasion serves, in correcting this popular error, and spreading a knowledge of the facts. It is no less than a duty. If every human being should do what he can to promote the general happiness, it would be downright wicked to leave one's fellow-men under the influence of hallucinations that debar them from the most charming of quiet pleasures. I suspect also that the misapprehension of the public is largely due to the conduct of experts in the past. It was a rule with growers formerly, avowed among themselves, to keep their little secrets. When Mr. B.S. Williams published the first edition of his excellent book forty years ago, he fluttered his colleagues sadly. The plain truth is that no class of plant can be cultivated so easily, as none are so certain to repay the trouble, as the Cool Orchids.
Nearly all the genera of this enormous family have species which grow in a temperate climate, if not in the temperate zone. At this moment, in fact, I recall but two exceptions, Vanda and Phalœnopsis. Many more there are, of course—half a dozen have occurred to me while I wrote the last six words—but in the small space at command I must cling to generalities. We have at least a hundred genera which will flourish anywhere if the frost be excluded; and as for species, a list of two thousand would not exhaust them probably. But a reasonable man may content himself with the great classes of Odontoglossum, Oncidium, Cypripedium, and Lycaste; among the varieties of these, which no one has ventured to calculate perhaps, he may spend a happy existence. They have every charm—foliage always green, a graceful habit, flowers that rank among the master works of Nature. The poor man who succeeds with them in his modest "bit of glass" has no cause to envy Dives his flaunting Cattleyas and "fox-brush" Aerides. I should like to publish it in capitals—that nine in ten of those suburban householders who read this book may grow the loveliest of orchids if they can find courage to try.
Odontoglossums stand first, of course—I know not where to begin the list of their supreme merits. It will seem perhaps a striking advantage to many that they burst into flower at any time, as they chance to ripen. I think that the very perfection of culture is discounted somewhat in this instance. The gardener who keeps his plants at the ne plus ultra stage brings them all into bloom within the space of a few weeks. Thus in the great collections there is such a show during April, May, and June as the Gardens of Paradise could not excel, and hardly a spike in the cool houses for the rest of the year. At a large establishment this signifies nothing; when the Odontoglossums go off other things "come on" with equal regularity. But the amateur, with his limited assortment, misses every bloom. He has no need for anxiety with this genus. It is their instinct to flower in spring, of course, but they are not pedantic about it in the least. Some tiny detail overlooked here and there, absolutely unimportant to health, will retard florescence. It might very well happen that the owner of a dozen pots had one blooming every month successively. And that would mean two spikes open, for, with care, most Odontoglossums last above four weeks.
Another virtue, shared by others of the cool class in some degree, is their habit of growing in winter. They take no "rest;" all the year round their young bulbs are swelling, graceful foliage lengthening, roots pushing, until the spike demands a concentration of all their energy. But winter is the most important time. I think any man will see the peculiar blessing of this arrangement. It gives interest to the long dull days, when other plant life is at a standstill. It furnishes material for cheering meditations on a Sunday morning—is that a trifle? And at this season the pursuit is joy unmixed. We feel no anxious questionings, as we go about our daily business, whether the placens uxor forgot to remind Mary, when she went out, to pull the blinds down; whether Mary followed the instructions if given; whether those confounded patent ventilators have snapped to again. Green fly does not harass us. One syringing a day, and one watering per week suffice. Truly these are not grave things, but the issue at stake is precious: we enjoy the boon of relief proportionately.
Very few of those who grow Odontoglossums know much about the "Trade," or care, seemingly. It is a curious subject, however. The genus is American exclusively. It ranges over the continent from the northern frontier of Mexico to the southern frontier of Peru, excepting, to speak roughly, the empire of Brazil. This limitation is odd. It cannot be due to temperature simply, for, upon the one hand, we receive Sophronitis, a very cool genus, from Brazil, and several of the coolest Cattleyas; upon the other, Odontoglossum Roezlii, a very hot species, and O. vexillarium, most decidedly warm, flourish up to the boundary. Why these should not step across, even if their mountain sisters refuse companionship with the Sophronitis, is a puzzle. Elsewhere, however, they abound. Collectors distinctly foresee the time when all the districts they have "worked" up to this will be exhausted. But South America contains a prodigious number of square miles, and a day's march from the track carries one into terra incognita. Still, the end will come. The English demand has stripped whole provinces, and now all the civilized world is entering into competition. We are sadly assured that Odontoglossums carried off will not be replaced for centuries. Most other genera of orchid propagate so freely that wholesale depredations are made good in very few years. For reasons beyond our comprehension as yet, the Odontoglossum stands in different case. No one in England has raised a plant from seed—that we may venture to say definitely. Mr. Cookson and Mr. Veitch, perhaps others also, have obtained living germs, but they died incontinently. Frenchmen, aided by the climate, have been rather more successful. MM. Bleu and Moreau have both flowered seedling Odontoglots. M. Jacob, who takes charge of M. Edmund de Rothschild's orchids at Armainvilliers, has a considerable number of young plants. The reluctance of Odontoglots to propagate is regarded as strange; it supplies a constant theme for discussion among orchidologists. But I think that if we look more closely it appears consistent with other facts known. For among importations of every genus but this—and Cypripedium—a plant bearing its seed-capsules is frequently discovered; but I cannot hear of such an incident in the case of Odontoglossums. They have been arriving in scores of thousands, year by year, for half a century almost, and scarcely anyone recollects observing a seed-capsule. This shows how rarely they fertilize in their native home. When that event happens, the Odontoglossum is yet more prolific than most, and the germs, of course, are not so delicate under their natural conditions. But the moral to be drawn is that a country once stripped will not be reclothed.
