Never since Roses have been cultivated in England to any extent has such a fatal season as the past been experienced by the growers. The severe frost in winter killed nearly all the buds of the Tea-scented and other delicate Roses, and numbers of the plants. The dry weather in March and April destroyed from half to two-thirds of the stocks planted in December; and the frost on the 25th of April so injured the young and tender shoots, which were soon after smothered with aphides, that scarcely any Roses bloomed at their usual season in June and July. It was not till August that the Hybrid Perpetuals showed themselves in character, and after that they flowered satisfactorily. As usual with a favored class of Roses like the above, we are inundated with so-called novelties from France, plenty of variety in names, lacking, however, difference in character; but there are some few really good and distinct, and quite worthy of a few words of praise, and so I will endeavor to describe them. Hybrid Perpetuals are the Roses of the day; they seem destined to supply all out-door wants at least, and one is never tired of their varied beauties.

There were forty or more Roses of this class alone, with new names introduced last winter and spring, most of them of the same unvarying tints of "rose," "pale rose," and so on; many of them really good, but not differing enough from well established varieties to make them acceptable to the amateur. There are, however, few and a very few, distinct, good, and acceptable to all lovers of Roses; and who is not? Holding a first rank among the few is Jules Margottin, which is quite worthy of its descriptive English name, Perpetual Brennus; its very vigorous habit, and large finely-shaped light vivid crimson flowers, remind us much of that very fine old Hybrid China Rose, Brennus. For growing on its own roots, and pegging down, for a pillar Rose, and as a standard, it is equally well adapted, and will soon be in every Rose garden. Sir John Franklin and Gloire de la France are of the race of the Geant des Batailles, and two fine robust growing Roses; the former bright red, the latter more approaching to deep crimson; they are two fine varieties. General Jaqueminot is, like the above, one of our new Roses, and most striking, from the size of its flowers, which are of rich shaded crimson.

It has, however, two faults - its flowers are not sufficiently double, and its habit of growth is rather slender and delicate. We now require Roses perfect in all points; large and double flowers, opening freely, fine healthy foliage, and a vigorous hardy habit Duchess of Norfolk will probably form a nice pillar Rose. Now we come to a host of new names applied to Roses, with shades of rose color and pink, such as Alphonse de Lamartine, Colonel de Rougemont, Madame Damage (both varieties of the race of Baronne Prevost), Ceres, Glorie de Parthenay, La Ville de St Dents, Lady Milsom, Madame Hector Jacquin, a large and vigorous growing Rose. Madame Harriet Stowe, Aline Gilbon, Mademoiselle Quetel, Marie de Bourges, Scphora, Triomphe en Beaute, James Veitch, Leon Plee, and several others, all pretty enough - for what Rose is not! - but with very little distinction in their characters. Gcrvaise Rouillard is a cheat; it is the old Hybrid China, General Lamoricere. Some few of the Roses among the Hybrid Perpetuals introduced, in 1858, have bloomed this season in great perfection, and have proved themselves worthy of a place in every Rose garden.

Such are Prince Leon Hotsehoubey, or simply Prince Leon, which is a shorter and better name. and Paul Dupuy, two charming Roses. Alexandrina Bachmeteff, with its brilliant carmine flowers, is also a great acquisition, as is another Rose, with a tiresome Russian name Prince Chi-petouzikoJJF, with brilliant deep flowers; Adame Paul is too double and large to open well in our climate. Souvenir de Leveson Gower is a magnificent crimson and first-rate Rose, and Hriemphe de Paris, very dark crimson, has also bloomed beautifully. Lady Stuart, of the same color, is not equal to Madame Rivers. Victoria has not opened well, and seems tender, as it suffered much by the winter. Archimede, Volta, and Ferdinand Deppe, are good rose-colored and pink Roses, but not distinct enough. Among Bourbon Roses we have but one this season really worthy of attention, viz., La Quintinie; this is most superb, its deep crimson flowers are of the most perfect shape; but it has one fault, it is delicate in its habit, and requires the highest cul-vation. Francois Henrica, also a new Rose of this class, is too much like Prince Albert and Surpasse Cornice de Seine et Marnc In Tea-scented Roses, we have one really fine and distinct, viz., Gloire de Dijon; in its foliage, habit, and shape, and size of its flowers, it is almost an exact resemblance of the Bourbon Rose, Souvenir de la Malmaison, and, like that fine Rose, it requires dry warm weather to open its flowers in perfection.

Its perfume is Tea-like and powerful, and in color it is quite unique, being tinted with fawn, salmon and rose, and difficult to describe. Auguste Vacher is also a new Tea Rose, perhaps too much like Noisette Ophirie in color and habit to be highly esteemed. It is long since we have had any new and good Noisette Roses; but this season a new variety called Augusta has been sent from America, which has bloomed in great perfection; it is of the race of Solfaterre, and resembles it closely in habit; its flowers are, however, more double and globular, remarkably elegant in shape, and in the center of its flower it is a little deeper in color. Another new Noisette Rose is Marie Charge, of the Ophirie class; its flowers are larger, more brilliant in color than that well-known Rose, and its habit seems very vigorous and hardy. - T, Rivers, in Gardeners' Chronicle.
