Harvest Tips
Cut flower spikes when the lower third of the flowers have opened for the longest vase life (7-10 days). Best cut in early morning when stems are fully hydrated. For dried flowers, cut at full bloom and hang upside down in a dark, well-ventilated area for 1-2 weeks. Allow some spikes to remain for seed dispersal and wildlife habitat.
