My Maryland (HT) [Madonna x Enchanter] According to E. G. Hill (The Rose Annual, 1913): "My Maryland, a lovely pink, must be kept at 65° or it will go to sleep in mid-season." And from the 35th Annual Report of the New Jersey State Agricultural Experiment Station 1914, "The My Maryland rose succeeds best when the night temperature does not fall much below 61 or 62 degrees."

American Florist 29: 818 (Nov. 9, 1908)

John Cook, the rosarian, and the dean now, so far as we can ascertain, of the trade here, both by virtue of his years and term of active service, is showing several batches of his new pink rose, planted at different dates, and all now coming into full crop. The rose is one of thousands of his hybridizing, the seed-bearer being his white rose Madonna and the pollen from from his pink Enchanter. The rose shows great size (in one house of the earliest planted many of them are of the size of American Beauty) stiff and long stems, the color a clear self-colored pink, without shadings or markings, and the fragrance of the Damask rose. Extremely floriferous, hardy of constitution, almost absolutely resisting mildew, every shoot bearing a bud, Mr. Cook esteems this his greatest achievement in producing new sorts, and this the rose by which he will be remembered by the craft. The sight of the special house devoted to this new product (there are benches in several others to test varying conditions) is certainly one which will warm the heart of every lover of the rose. A number of growers have visited Mr. Cook's place to view the new queen. Amongst others Augustus and William C. Gude, A. Farenwald, Frederick Hahman, Wm. Graham and others, of Philadelphia, and nearly everybody concerned with rose growing in this locality. A great quantity of the rose is being propagated, but so far nothing has been determined upon as to its dissemination. All who have seen it are, however, anxious to possess some of the stock, and it is entirely reasonable to expect quite a furore for it when put upon the market. S. B.
