Excellent cut flower but they must be conditioned correctly. Hollyhocks have hollow stems which need to be filled with room temperature water immediately after being harvested. Plug the stem with cotton wool. To eliminate small air bubbles, pierce the stem with a pin just below the flower head. If flowers stems are recut, you will need to repeat this process. Let stand over night before using.
