As the formation of a rose bed is not designed for the season only in which it is planted, but to remain permanently, annually increasing in growth and beauty, it is there -fore necessary to select those best adapted in habit, growth and variety of flowers to accomplish these results. From the large number of varieties now grown in this country, it would seem that little difficulty should be experienced in making the proper selections, and indeed it is true, a rose bed composed of the popular old varieties may at all times be an object of admiration and interest, still we think the general appearance and effect can be vastly improved by choice selections and proper arrangement. Generally, the amateur prefers the bed to contain individual plants properly assorted and arranged, harmonious in form and varying in color of flowers, rather than comprising one entire color, however rich. And in this we believe him to be correct, unless he has a large garden in which collections of specific colors can be formed in groups, or an extensive lawn, where a rosarium can be artistically and tastefully planted with all the groups in variety and also in masses of definite colors for producing the finest effect and beautiful contrast.

For single beds to complete desirable results during the entire season, the varieties should consist of selections from the classes or groups, known to rose growers in their specific names, as Noisettes, Bourbons, Hybrid Perpetuals, Teas, etc., each possessing qualities of peculiar merit, and from these we are to select. As stated in a former article, the novelties and improvements of the varieties in some classes has indeed been very striking, and we could name many combining the most desirable qualities suitable for enriching a choice bed, but to do so at present, might deter many from enjoying a good rose bed, by their inability to procure them in quantities, owing to the scarcity and consequent high price. Therefore we propose to name some of those of known merit, mostly grown from importations of the past five or six years, in connection with the deservedly esteemed older varieties, now raised by most of our florists, who give any attention to propagating the rose. The usual form is a circular bed. In one of fifteen feet in diameter, four circular rows can be planted with roses two feet apart and two feet from each other around a center.

The center and first circle should be planted with the most vigorous and erect-growing varieties for training to stakes from four to six feet in height. The roses well suited for this purpose are, Hybrid Perpetuals, Glory of Waltham,.Genl. Jacqueminot, Le Enfant du Mt. Carmel, Madame Baronne de Rothschild, Madame Chirard, Madame Barriott, Duchess of Sutherland, Jules Margotten, Thyra Hammerick, Geant des Battailles, Paul Neron, Baronne Hausmann, and Noisettes, Washington, Margarite, Ophyrie and Solfaterre. (These may be classed as pillar roses, and any of them used as single specimens on lawns or in gardens for that purpose.) For the second circle from the center we would name other Hybrid Perpetuals of robust habit, but more moderate growth, as Comtesse D'Oxford, Prince Camille de Rohan, Xavier Olibo, Achille Gonod, Virgil, Princess Christian, Dr. Lemee, Genl. Washington, Aurora Borealis, Bertha Baron, Chas. Lefebvre, Coquette des Alps, Edouard Morran, Felix Genero, Jno. Hopper, La Reine, Madame Victor Verdier, Souv. de Wm. Wood, Reine Blanche, Vicomtesse de Vezins. Third circle from center: Bcur-bans, Souv. de la Malmaison, Hermosa, George Peabody; and Hybrid Perpetuals, La France, Marquise de Castellane, Marie Baumann, Pitord, Perle Blanche, Henri Pages, Beauty of Waltham, Alfred Colomb, Boule de Neige, Mons. Boncenne, Velours Pourpre, Victor Verdier and Lady Emily Peel. Fourth and outer circle may be planted six inches from the border and closer in the row with China Roses, as Agrippina, Archduke Charles, Ducher, Luc alius' Roi des Cramoisies, Louis Philippe, Mrs. Bosanquce Sanguines, White and Pink Daily. All named above are hardy varieties requiring little or no protection, but would be benefited and improved by having a liberal supply of coarse stable manure spread over the entire bed during the winter.

If desirable to have Tea roses in this bed, the outer circle might be composed in part or solely with them, in lieu of the Chinese, to be lifted in the fall, potted or heeled in a cold frame to be planted again in the spring.

Most of those named for a hardy rose bed, and particularly the strong growing varieties, are specially adapted for planting in low shrubbery borders, in lawns or gardens, producing fine effect when freely commingled with other shrubs, by the pleasing contrast of their brilliant and gorgeous blooms, with the delicate green leaves and beautiful flowers of many of the new and hardy shrubs.

A bed composed entirely of Tea-scented Roses would be the greatest luxury in flowers the amateur could possibly possess, but in our climate, and farther north where the thermometer sometimes descends to aero, it is doubtful whether we will ever succeed in growing and enjoying all the varieties, though there are instances of individual strong and vigorous varieties having been grown successfully in the open air for years, but if ever thoroughly successful, it must be accomplished by extra care in protecting them for several months during the winter season. This is owing, in a great measure, to the natural habit of the Tea Rose in growing and flowering so late in the season, thus failing to ripen their wood sufficiently to encounter and endure the long continued dry and cold winds that prevail so often during the winter season; therefore, to rely upon a successful bed of Tea Roses, we can only recommend their being lifted from the beds late in the season and potted, or heeled in a pit, cold frame, cellar or other protected place, to be again planted in the spring, and, indeed, they are worthy of this attention and extra care, which they fully repay by their continuous beautiful and delicate blooms of delicious odor.

For a circular bed, or beds similar to that for Hybrid Perpetuals, the center and first circle should be planted from selections of the strong-growing double varieties for training to stakes. They are mostly composed of those having the marked characteristics of the Noisette, to which they are nearly allied, as Gloire de Dijon, Madame Celina Noirey, Madame Trifle, Madame Ber.rd, Marie Sisley. Le Florifere, Madame Gail-lard, Mad. Emily Dupuy and Monplaisir.

For the second circle those of good habit, but less vigorous in growth, as Devoniensis, Safrano, Madame Azelie Imbert, Isabella Sprunt, Madame Russell, Marie Van Houtte, Souv. d'un Amie, Triomphe de Luxemburg, Hortensia, Homer, La Pactole, Comtesse Ouvaroff, Souv. de Paul Neron, Perfection de Monplaisir.

For the third circle those of moderate growth, as Belle Maconnaise, Coquette de Lyon, Annette Seaut, Sulphurieux, Catharine Mermet, Hypolite, Souv. de Elise, Comtesse de la Bath, Madame Ducher, Jean Pernet, Madame Jules Margotten. In the outer circle those of short growth, as Victor Pul-liat, La Jonquille, La Boule d'or, La Nankin, Ma Capucine, Comte de Gravel, Madame de Narbonne, Jeanne d'Aro, Bianqui and Bella. As we have named some varieties in the different circles grown from recent importations, the habits of which are not fully established, these from year to year may be varied in position, as the tendency of the variety may prove more or less vigorous in growth.

The Tea Rose is indeed the best class for greenhouse culture, and a richer treat cannot be enjoyed than that produced by a house filled with them, constantly developing buds and blossoms, continuing longer during the year than any other flowering plant, the flowers also attaining greater perfection than can possibly be had in open air culture. They may bo planted as above, only placing those of running habit to be trained to the rafters and pillars.
