Growth Stages

1

Tuber Dormancy

October-March (northern zones)

The rhizome is dormant and compact, typically stored bare or in damp sand

Store at 40-50°F in winter; keep tuber slightly moist but not waterlogged. Inspect for rot or damage before spring planting.

2

Initial Growth

2-4 weeks

New leaves emerge from the tuber and begin unfurling; initially submerged or just breaking the water surface

Plant in spring when water temperature reaches 60°F. Ensure tuber crown sits at soil surface. Check for pest damage on emerging leaves. Apply first fertilizer tablet 2-3 weeks after planting.

3

Vegetative Expansion

3-6 weeks

Multiple leaves float on the water surface with reddish undersides; plant fills its allocated space with foliage

Remove damaged or yellowing older leaves. Thin leaves if overcrowding occurs to improve air circulation and light penetration. Apply fertilizer every 3-4 weeks. Monitor water quality and depth.

4

Flowering

June-September (8-12 weeks or longer)

Star-shaped lilac-pink flowers emerge on stems and float on the surface; blooms open in morning and close by afternoon

Flowers bloom from June through September. Remove spent flowers daily to encourage continuous blooming. Maintain consistent water temperature and nutrients. Ensure adequate sunlight—blooms require minimum 6 hours daily.

5

Seed Pod Formation & Dormancy

September-November

After flowering, seed pods may develop underwater; foliage gradually reduces as temperatures cool in autumn

Allow some flowers to set seed if seed propagation is desired; otherwise remove spent flowers. As water temperature drops below 60°F, reduce fertilization. In fall, prepare tuber for winter dormancy by thinning dead foliage.

Companion Planting

Plan your garden →

Plant with:

Water hawthorn (Aponogeton distachyos) Pickerel rush (Pontederia cordata) Water iris (Iris laevigata) Marsh marigold (Caltha palustris) Horsetail (Equisetum fluviatile) Watercress (Nasturtium officinale)

Avoid planting near:

Aggressive floating plants (water hyacinth, water lettuce) that shade the lily Tall emergent plants that block sunlight Allelopathic plants releasing growth-inhibiting compounds (avoid black walnut runoff) Fish that uproot rhizomes (grass carp, koi in shallow containers)

Common Pests

  • Spray with insecticidal soap or neem oil; submerge affected leaves briefly; introduce natural predators like water boatmen. In ponds, increase water circulation.

  • Remove affected leaves and discard; spray with neem oil during early infestations. Improve water quality and aeration to discourage beetles.

  • Remove and discard heavily spotted leaves. Improve water circulation and reduce organic debris. Avoid overhead watering; use fungicide tablets formulated for aquatic plants if severe.

  • Ensure soil is heavy clay, not peat-rich. Maintain good water quality and aeration. Remove affected tubers immediately. In containers, change water regularly and avoid stagnation.

Harvest Tips

Water lilies are ornamental and not harvested for food. Pinch off spent flowers daily (they close by evening anyway) to encourage continuous blooming. Seed pods form underwater; collect and dry them in late summer if propagating from seed. Tubers can be divided in spring when new growth appears—gently separate using a clean knife, ensuring each division has at least one growth bud.

Fun Facts

  • 🌱 Laydekeri Lilacina is a dwarf cultivar developed by French nurseryman Joseph Bory Latour-Marliac in the late 1800s; it remains one of the most reliable compact water lilies for small spaces over 125 years later.
  • 🌱 Water lily flowers exhibit a fascinating heliotropic behavior—they open in the morning sun and close by afternoon, storing pollen inside to protect it from moisture and damage.
  • 🌱 The name 'lilacina' refers to the lilac or pale purple coloration of the petals; this pigmentation comes from anthocyanin compounds also found in grapes and blueberries.
