Listed among their "Ever-blooming Tea Roses"

"MADAME RIVOY.* Looks like a Hybrid Perpetual in Flower and Foliage. Is Hardy. In this grand old variety we have a Rose of no ordinary excellence. It is entitled to a place among Ever-blooming Roses equal to that which General Jacqueminot takes among Hybrid Perpetuals. Indeed it is not unlike a Hybrid Perpetual in the extra-large, full and loosely-formed double flowers, enchanting fragrance, intensity of color, large handsome foliage, and extreme vigor of growth ; it is hardy with slight protection, a quick, constant and profuse bloomer, and for outdoor culture cannot be excelled by any Rose of its color. The flowers are produced in wonderful abundance upon long stiff stems, and in color may be described as a rich crimson scarlet; very bright and effective. We doubt if any of our customers have ever seen this lovely Rose, and it is for their benefit, that all may secure one of the finest and best Roses grown, that we call special attention to it by our truthful illustration."
