Planting
1-2 weeksWater lily rhizome or tuber is planted in heavy soil in a container with the growing tip just above soil level.
Use aquatic planting containers with drainage. Fill with heavy loamy soil or clay, compress gently, and submerge in warm water. Ensure water temperature is at least 70°F to initiate growth.
Establishment
2-4 weeksNew leaves emerge and gradually rise toward the water surface; plant develops roots and establishes in the container.
Keep water warm and stable. Apply slow-release aquatic fertilizer tablets near the roots. Monitor for algae and debris on developing leaves.
Vegetative Growth
3-6 weeksMultiple floating leaves spread across the water surface in a rosette pattern; the plant becomes fuller and more vigorous.
Maintain water clarity and temperature. Fertilize monthly with aquatic plant fertilizer. Remove any yellowing or damaged leaves.
Flowering
12+ weeks (continuous from early summer through fall)Blue flowers with prominent yellow stamens emerge from the water surface on stems, typically opening in the morning and closing by afternoon.
Provide maximum sunlight (8+ hours). Continue monthly fertilization. Remove spent flowers to encourage continuous blooming. Flowers typically last 3-4 days each.
Dormancy/Overwintering
Variable (winter or until water warms)In cooler climates or as water temperature drops below 60°F, the plant slows growth and may lose leaves.
In zones 10-11, maintain warm water year-round for continuous growth. In cooler areas, treat as annual or move indoors to warm water. Cut back dead foliage and reduce fertilizing.
