Autumn Joy Stonecrop has inflorescences that are rosy-pink to rosy-bronze at the peak of their floral bloom. While some references list this hybrid as a cultivar of Sedum spectabile, this is not correct, as the inflorescences of 'Autumn Joy' are mounding hemispherical and almost non-fragrant (rather than flat and very fragrant), and the leaves are spirally arranged along the stems (rather than opposite and whorled).
