Moss Roses first appeared as mutations of Centifolia roses in 1720, in which the sepal, calyx and stems have a mossy growth. This is particularly attractive in the bud stage and has a noticeable balsam-like fragrance when touched. Later repeat flowering and more compact hybrids evolved from the Damask roses, although these do tend to be rather less mossy. Very popular with the Victorians who relished such curiosities.
Prune as for Albas in once-flowering varieties and for Autumn flowering Damask with the repeat flowering sorts.
