Dormancy/Rhizome Establishment
2-3 weeksNewly planted rhizome develops roots and begins leaf growth; no visible blooms yet
Keep water temperature consistently warm (75-85°F); ensure adequate light reaches the rhizome; apply aquatic fertilizer pellets monthly
Vegetative Growth
3-4 weeksMultiple floating leaves emerge and expand; lily pad clusters form on water surface
Fertilize every 3-4 weeks with aquatic plant fertilizer; thin overcrowded leaves to allow light penetration; monitor water depth and temperature
Bud Formation
1-2 weeksFlower buds develop among the floating leaves, appearing as small rounded nodules beneath the leaf pads
Maintain consistent warm temperatures and 6-8 hours of sunlight daily; continue regular fertilizing; ensure water is clean and free of debris
Flowering
3-5 months (June-September in temperate climates)Blooms open in morning, showing peachy-pink petals that deepen to red; flowers close by afternoon; multiple blooms appear throughout season
Keep water level consistent; remove spent flowers to encourage more blooms; maintain fertilizer schedule; water temperature critical (70°F+ minimum)
Senescence/Dormancy
2-3 months (October-December in temperate climates)Flowering declines as water temperature drops below 60°F; leaves yellow and deteriorate; plant enters dormancy in fall
In zones below 10, either drain pond and store rhizome in moist sand indoors, or move container to frost-free location; in warm zones, water lily may persist year-round

Harvest Tips
Water lilies are ornamental; harvest flowers by cutting stem at water line just after opening. Blooms typically last 2-3 days; remove spent flowers daily to promote continuous flowering. Petals and buds are edible in some varieties (though 'Sioux' is primarily ornamental) and can be used fresh in salads or as garnish. Propagate by dividing rhizomes in spring.
Fun Facts
- 🌱 The Sioux water lily is a hybrid cultivar that was developed to thrive in warm climates and produce multiple blooms per season; it is a tropical day-blooming variety, meaning flowers open during daylight hours and close at night.
- 🌱 Water lily leaves (lily pads) have a special waxy coating and air pockets underneath that allow them to float; the 'Sioux' variety produces particularly large, attractive pads up to 12 inches in diameter.
- 🌱 Unlike night-blooming water lilies, the Sioux variety's flowers are visited by bees and other diurnal pollinators, making it ecologically valuable in ornamental water gardens.
