Harvest Tips
Not typically harvested for use; instead, deadhead spent flower spikes to encourage continuous blooming. Remove flowers at the base of the spike where blooms have faded. In zones 9-11, cut back stems by 1/3 in late winter to rejuvenate. In cooler zones, dig up plants before first frost to save as cuttings or bring entire potted plant indoors.
