Dormancy & Planting
1-2 weeksRhizomes are dormant in early spring; plant in aquatic baskets with soil mixture just as water warms
Start plants in spring when water temperature reaches 60°F; use heavy aquatic soil in planting baskets to anchor plants
Leaf Development
3-4 weeksFloating leaves emerge and unfurl on the water surface; leaves are round, glossy green, and may have reddish undersides when young
Remove any algae competing with young leaves; ensure water clarity; maintain consistent water depth
Vegetative Growth
4-6 weeksExtensive floating leaf pads spread across the pond surface; plant develops strong root system and multiple growing points
Allow leaves to spread naturally; thin if they cover more than 50% of pond surface; fertilize monthly with aquatic plant fertilizer

Fun Facts
- 🌱 Nymphaea odorata var. alba flowers are uniquely adapted to open and close with the sun, typically opening at dawn and closing by late afternoon—a behavior called nyctinasty that conserves pollen and protects the flower from nighttime moisture.
- 🌱 The genus name 'Nymphaea' derives from Greek mythology, named after water nymphs, and the species 'odorata' refers to its distinctly sweet, vanilla-like fragrance that strengthens in warmth and can perfume an entire garden.
- 🌱 This species is the state flower of South Dakota and has been cultivated for thousands of years, appearing in ancient Egyptian art and being used medicinally by Native Americans across North America.
