Harvest Tips
Water lilies are ornamental flowers grown for beauty rather than harvest. Cut blooms early morning (8-9 AM) when fully open if desired for floral arrangements; they will remain fresh in a vase for 2-3 days in cool water. Allow flowers to mature on the plant for maximum garden display. Seed pods may be collected in late summer if you wish to propagate from seed (advanced technique).
Fun Facts
- 🌱 Swan Lake water lilies are night-bloomers in some variants and day-bloomers in others; this cultivar is a diurnal day-bloomer that opens in morning light and closes by afternoon, following the sun's cycle.
- 🌱 Water lilies have been cultivated for over 3,000 years, with ancient Egyptians considering them sacred symbols of rebirth and the afterlife, depicted in hieroglyphics and temple art.
