HYBRIDIZING
John Cook
I have one now which has good points for commercial winter work. It is the second generation of my white seedling, Madonna, and Enchanter. It has a stronger growth than either of them, stiff stem and large pink flowers, a shade lighter than Enchanter.

GROWING ROSE SEEDLINGS.
John Cook, Maryland.
In 1908 I introduced Radiance, a rose pink with a silver lining to the petals. This is a seedling from Cardinal crossed with an unnamed pink seedling. This rose received a silver medal at the Hartford Test Gardens, and this, in my opinion, is the very best of all the Hybrid Tea Roses for out of doors. The demand for this rose is increasing every year.

RADIANCE (Cook, 1904) For many years after this variety was introduced by Peter Henderson in 1908, it was the most widely distributed of all Hybrid Teas in America, and now, almost fifty years later, it is still recognized as one of the best pink varieties. Its vigor, tolerance of different climates and soils, comparative disease resistance, and large, fragrant, cameo-pink blossoms of 23 petals were directily responsible for the later popularity of the Hybrid Teas as garden plants. Radiance was the most famous of the more than 25 varieties produced by John Cook of Baltimore during nearly fifty years of breeding work, and was the result of crossing Enchanter X Cardinal, both previous Cook introductions.

Dr. J. H. Nicolas, certainly a most painstaking and successful hybridizer who, in answering a query as to Radiance possibilities writes: "Radiance is the most obstinate and selfish breeder. I have, perhaps, done more Radiance breeding than anyone else on earth, and got nowhere. It seems as if the color and plant characters were welded together, and, like Mary and her little lamb, one goes where the other does."

Then Dr. Nicholas gives the detailed history of his attempts, working through several generations to preserve the globular form and the growth characters of John Cook's inspired rose. He has worked with the Pernetiana group and in every other direction, using not only Radiance itself but its sports. He ends his observations by saying—"I have given up breeding Radiance as a bad job."

Bosley (1937) "Some sorts, like Radiance, seem so firmly fixed that all efforts to improve the strain seem useless. Many times we have found improvement on members of the Radiance group, only to find, next year, that it went back to the type again."
