Fun Facts
- 🌱 Blue Beauty water lilies were hybridized and popularized in the early 20th century; the blue color in tropical water lilies comes from anthocyanin pigments absent in hardy water lilies, which is why true blue varieties are exclusively tropical.
- 🌱 Water lilies exhibit nyctinasty—a circadian rhythm where flowers open during the day and close at night, helping protect pollen and attract daytime pollinators while conserving energy.
- 🌱 The leaves of water lilies have a special waxy coating and air-filled pores that allow them to float effortlessly and repel water, much like the famous lotus effect studied in biomimicry and nanotechnology.
