"Could you," asked George Adam, "tell me the story of the Peace rose from the beginning?" The event occurred about 1950, and here is how my grandfather [Francis Meilland] answered:....
The female element of Peace was Johanna Hill, while the male element came from a budding stock filled under the number 103-32-A, that is, brought into existence in 1932, and was the product of a cross between Charles P. Kilhan and Margareth MacGredy.
Why did we attempt the combination which became the Peace rose? Let me first mention the combination that resulted in 103-32-A. I still recall it vividly, though twenty years have gone by since then. Our purpose was to achieve a hardy foliage and good winter resistance in a rose of a copper color. We had taken the pollen of Margareth McGredy, which we greatly admired because of its qualities as a strong, hardy plant, and had chosen as the female element Charles P. Kilhan, which we thought capable of transmitting to its descendants, its own characteristic form and color pattern.
From this first cross a vigorous rosebush resulted with a bicolor flower. Its colors were very brilliant, but its form left something to be desired. Even the blossoming of this flower was somewhat capricious, magnificent at certain times and, frankly, homely at others. We thought for a moment of improving this variety of which we had grown a fair selection. But the project was abandoned, for it seemed to us that the desired result had not been obtained. Finally we crossed Johanna Hill with this 103-32-A, having in mind a high branching rosebush of great hardiness, and a healthy and decorative foliage like that of Margareth MacGredy. We hoped that a color pattern would evolve between yellow and bicolor yellow-red, that is, with an extensive range of colors."....
