Harvest Tips
Cut flower spikes when the first florets open, leaving at least 2-3 sets of leaves on the stem. Flowers bloom sequentially upward, so harvest in the morning for longest vase life (7-10 days). For ornamental enjoyment, leave flowers on the plant and deadhead faded spikes to encourage more blooms.
