IN my last month's communication on New Roses, I named several varieties of Hybrid Perpetuals and Teas flowering for us during the past summer, and referred to the success of the European growers in hybridizing. We, as lovers of this beautiful flower, owe, indeed, much to the skill and persevering labor of the French in producing from their extensive beds of seedlings, plants of the greatest vigor, and flowers of the finest forms and the most exquisite beauty. The credit of each grower is staked on every new variety issued, and annually they must send out those of equal merit, if not superior to former productions, or their reputation as growers or originators, under the rigid animadversion of the amateur and professional critics of England, would soon decline, and their pecuniary prospects suffer. Then is it not natural that from year to year, we may look for some novelties and worthy additions to our present collections? Whilst by their great zeal and activity, the French excel others in producing new varieties, and the English, by their careful and thorough cultivation, accomplish the finest exhibitional results, we, in this country, should, from our favorable climate, purity of air, and hot summer suns, not only ripen the best seed for growing plants, but produce plants bearing the most perfect flowers.

Our climate differing materially from that of England and France, leads many to suppose that some varieties and groups do not attain as perfect growth as with them, which may, in some instances, be the case. Yet generally, from our observations, those of robust and vigorous habit do equally well, and from many of the new varieties we have had flowers comparing favorably in size, form, and brilliancy of color, with those exhibited at the special shows held annually at the Crystal Palace, London; and even in some instances, those classified by them as second rate have, under our hot suns, proven excellent growers, producing elegant flowers, and entitling them to first rank with us.

The hardy Hybrid Perpetuals, and more tender Teas, are the two classes or groups to which the French growers have given their closest attention; and in the former the most striking novelties have been produced. Only a few years ago, the list of Hybrid Perpetuals numbered less than fifty in all, now there are many hundred varieties. By skillful hybridizing of species, and commingling with others of same class, they have not alone retained the strength and vigor of the best older kinds, but in many instances increased vigor and robust habit has been added, together with brilliant and showy foliage, and beautiful flowers of the finest forms, and most exquisite colors, from the purest white, delicate rose, pink, and brilliant scarlet, to the deepest and richest crimson. By this same skillful mode of hybridizing, we have now in this group, roses blossoming freely during the entire summer, such as the pure white " Coquette de Alps," "Boule de Niege," and the delicate rose-colored "La France," "Madame La Ba-ronne de Rothschild," " Madame George Schwartz," and many others.

This group, from its hardy qualities and luxuriant habit of growth, is specially adapted to open ground culture, and a bed planted with a choice selection of varieties cannot fail to call forth general admiration, as one of the most beautiful objects on a well designed lawn, or carefully cultivated flower garden; or when properly arranged with other medium sized shrubs, take a leading rank in the grouping; and some varieties of erect habit of growth are particularly adapted for pillar shrubs standing singly on the lawn or in the garden. In their growth they require at little, and in many cases less, care than other shrubs and flowers, only asking a rich and generous soil, full circulation of air, and bright sun.

• Flowers of H. P. Paul Neron, in our own grounds, measured 54 inches in diameter.

In Tea Roses the novelties are less striking to the amateur, than in the group of Hybrid Perpetuals, from the natural color of the flowers being more subdued or less brilliant, though even in these brighter colors are being introduced, but probably they will never attain that distinctive brilliancy of the Hybrid Perpetuals. Matchless among other groups, for their delicious perfume, rare and delicately tinted flowers, easy grace, and sprightly bearing of both plant and flower, they will remain for many years the gems of the race.

But few, if any, of the Teas of former years exhibit the rich, vigorous growth of the very double deep rose-colored " Madame Celina Noirey," delicate saffron " Madame Berard " or salmon-yellow " Madame Trifle," and none the perfection, delicacy and richness of color superior to the nasturtium - colored " Ma Capucine," and coppery-yellow " Le Nankin; " the refined colors of the two last named cannot indeed be fully described, and can only be enjoyed by seeing their beautiful blooms of half-extended golden and coppery buds. The more double flowers than those last named, as " Madame Jules Margotten," "Perfection de Monplaisir," " Souvenir de Paul Neron," " Belle Macon-naise," " Marie Sisley," " Marie Van Houtte," " Reine du Portugal," "Madame Margotten" and "Adrienne Christophle," are composed of a beautiful combination of colors, some having pure white, others light yellow outer petals, with centers shading to eoppery-yellow, rose and scarlet. This group blooming freely during the summer, and continuing to grow and flower late in the autumn, does not usually ripen its wood sufficiently to bear our severe winters, without some protection, though by carefully covering with leaves or other light material for several seasons, until they become thoroughly established, they may be made to thrive, and blossom thereafter, with. but slight shelter and care.

They make a luxuriant growth when planted early in the season, and blossom freely after July, even from the smallest plants, and do well in any rich soil properly drained. Some varieties may be grown to advantage in pots for greenhouses and conservatories, whilst others, of climbing habits, are ornamental when trained up the rafters; but to grow to perfection, a house filled with Tea roses, producing a profusion of rich, green leaves, with a constant and perfect development of flowers varying in color, and embalming the air with delicious perfume, affords a delight and gratification that no other group or flower can give. In my next, I purpose naming a few varieties of Hybrid Perpetuals and Teas, suitable for bedding in masses, pillars, climbing, and growing in greenhouses.
