Harvest Tips
Night-blooming water lilies are ornamental plants not typically harvested for consumption. To enjoy the flowers: observe blooms opening at dusk and closing at dawn. Cut mature flowers in early evening if desired for floral arrangements; they will remain open through the night. Remove spent flowers and developing seed pods daily to encourage continuous blooming. Deadheading redirects plant energy to new flower production.
