Karma Dahlias Prospero®

Karma Dahlias Prospero®

Soft, lilac dahlia flowers with a hint of gold at the centers look absolutely stunning in bouquets and fresh floral displays. Prospero Karma Dahlia produces gorgeous lilac-pink flowers measuring up to 5 1/2" across starting in midsummer and keeps blooming until the first fall frost. Karma Dahlias were developed for the cut-flower market in Holland because of their extraordinarily strong stems and almost iridescent colors. We first came across these special dahlias while visiting the trial gardens of Verwer Brothers several years ago.
