"Its contribution to the rose world has been immeasurable. Because of its vigour and dependability, ‘Peace’ has been used in breeding programmes across the world. It is recorded that ‘Peace’ is the ‘mother’ in 150 varieties and the ‘father’ in a further 180 varieties. There would be many more if breeders always declared the parentage of new releases. Indeed it is probably safe to say that most of our modern roses are descended in some way from ‘Peace’...a few of the great garden roses that have ‘Peace’ in their lineage are: ‘Double Delight’, ‘Casanova’, ‘Blue Moon’, ‘Soaring Wings’, and ‘Electron’."
The lovely story of this mother & father of millions: https://www.gerbera.org/gardening-magazine/the-gardener-index/june-2005/peace-rose/
Developed by Meilland International on the eve of World War II, a clipping of the rose made its way from France to the Conard-Pyle Co. for safekeeping during the war. Coincidentally, the All American Rose Society named Peace its only winner for 1946 on the same day Japan surrendered, effectively ending the war.
“How strange to think that all these millions of rose buses sprang from one tiny seed no bigger than the head of a pin, a seed which we might so easily have overlooked, or neglected in a moment of inattention.” ~ Francis Meilland
