‘De Candolle’ is a moss rose bred by Portemer in 1857, found for sale only in one German and one French rose nursery. Light pink with a button eye, this full rose exhibits crinkled leaves much like a rugosa and allows no hold on its stems for the exuberance of bristles. It was named for the Swiss botanist, Augustin de Condolle (1778-1841) who improved Linneaus’ classification system, focusing on plant anatomy rather than physiology and taking into consideration the differences as well as the similarities of plants. He became the first director of Geneva’s botanical garden.
