Dormancy/Establishment
2-4 weeksRhizome is planted and begins sending out roots and a single leaf shoot; no visible above-water growth yet
Keep water temperature stable; ensure proper soil contact with rhizome; avoid disturbing the planting site
Vegetative Growth
4-6 weeksFloating leaves emerge and expand on the water surface, developing the characteristic round shape with notch; underwater stems elongate
Provide adequate light; apply aquatic fertilizer tablets near the roots; remove any dead or yellowing leaves; monitor for algae competition
Bud Formation
2-3 weeksLeaf production continues; flower buds begin forming on separate stems and push toward the water surface
Maintain consistent water level and temperature; continue fertilizing; thin overcrowded leaves if needed to allow light penetration
Flowering
8-12 weeks (mid-July through September)Delicate white or pale pink flowers with numerous petals and yellow stamens open on the water surface in early morning, closing by afternoon; flowers are highly fragrant
Deadhead spent flowers to encourage more blooms; maintain water quality; do not submerge flowers; provide 6+ hours of sun daily
Seed Pod & Senescence
4-8 weeksFlowers fade; seed pods develop underwater or float near the surface; leaf production slows; plant prepares for dormancy
Allow seed pods to develop if propagation is desired; reduce fertilizer; prepare for winter dormancy in cold zones; remove dead foliage

Harvest Tips
Water lilies are ornamental and typically not harvested for consumption, but flowers can be cut in early morning when fully open for floral arrangements (cut 1-2 inches below the water surface with a sharp knife). Flowers last 3-4 days in a vase. Allow some flowers to remain for garden display. In late fall or early spring in cold zones, seeds can be collected from mature seed pods for propagation; stratify in moist sand for 1-2 months before germinating.
Fun Facts
- 🌱 Nymphaea odorata is the state flower of South Carolina and is highly prized by water gardeners for having one of the most intensely fragrant flowers among water lilies—the fragrance is strongest on warm, sunny days.
- 🌱 Petals of fragrant water lilies open in the morning (usually around 9-11 AM) and close again by mid-afternoon, a behavior called nyctinasty that is thought to protect pollen and ensure pollinator visitation.
- 🌱 The plant's name comes from the Nymphs of Greek mythology, and it has been cultivated since at least the 19th century as the basis for numerous modern water lily hybrids and perfume production.
