Dormancy/Tuber
Seasonal (winter months in warm climates)Plant exists as a dormant tuber during winter or storage; dark, compact rhizome with growth nodes visible
Store tubers in cool, moist conditions (50-60°F) or keep in dormant ponds during winter. Inspect for rot and remove any damaged sections.
Sprouting
2-3 weeksFirst leaves emerge from the tuber; small, elongated leaves appear and begin moving toward water surface
Plant tuber in spring when water temperature reaches 60-65°F. Ensure pot is submerged and tuber tip points upward. Begin light fertilization.
Vegetative Growth
3-4 weeksFloating leaves expand and multiply; plant develops multiple leaf pads across water surface with increasing vigor
Apply aquatic fertilizer tablets monthly. Remove any yellowing or damaged leaves. Thin overcrowded foliage to improve air circulation and flower development. Monitor for pests.
Flowering
4-6 months (June-October in northern climates; year-round in tropical zones)Blue star-shaped flowers emerge on stems above water surface; blooms open in morning and close by evening. Multiple flowers appear simultaneously on mature plants.
Maintain consistent water temperature above 70°F for peak flowering. Continue fertilizing every 2-3 weeks. Deadhead spent flowers to encourage new blooms. Provide 6+ hours of direct sunlight daily.
Seed Development
4-6 weeks per flowerFertilized flowers develop into seed pods that mature beneath the water surface; pods eventually rupture to release seeds
Allow some flowers to develop seeds if breeding desired; otherwise deadhead to redirect energy into new flowers. Most gardeners propagate vegetatively via tuber division rather than seeds.

Harvest Tips
