Dianthus plant named ‘Raspberry Ruffles’

Abstract

A new and unique plant cultivar of perennial carnation or pinks, Dianthus plant named Raspberry Ruffles with numerous, large, fully-double, lightly-fragrant flowers producing a rounded full face. Individual flowers can have about 114 petals with irregularly toothed margins and raspberry coloration toward the middle and light pink to white margins. The numerous stems cover the top of the plant with flowers for about six weeks. The habit is compact with long, thin, blue-green foliage.

Claims
