How To Deadhead A Scabiosa. When each flower is on its own stem such as with Scabiosa plants it is best to deadhead the entire flowering stem rather than leaving a gangly headless stem attached to the plant. Cut the flower stems of spent blooms against the nearest leaves or active flower bud.
Cut the spent blooms from the cut stems and discard the stems. Remove flowers beginning with the terminal topmost bloom and work down toward the base of the plant. Cut the flower stalk just before the point where the leaves emerge if there is only one flower on the stalk.
Plant them in your desired location in an environment that closely mirrors that from which they came.
Sow seeds in a tray and pot on seedlings when large enough to handle. Cut the flower stalk just before the point where the leaves emerge if there is only one flower on the stalk. Remove flowers beginning with the terminal topmost bloom and work down toward the base of the plant. Pincushion flowers are normally grown by seed though container-grown plants may also be available.
