Harvest Tips
Not harvested for consumption. Deadhead spent flower spikes regularly (every 1-2 weeks during blooming season) by cutting just below the spent flowers to encourage more blooms. Cut back entire plant in late winter (February-March) in cold zones or lightly prune in warmer zones. Can be cut for fresh arrangements.
