Growth Stages

1

Dormancy & Planting

1-2 weeks

Rhizome is dormant or just beginning to sprout. No visible foliage above water yet.

Plant in spring in warm water (minimum 70°F). Use 12-18 inch diameter pots with heavy soil. Ensure water temperature will remain consistently warm.

2

Leafing Out

2-4 weeks

First juvenile leaves emerge and unfold on the water surface. Leaves are small and may be variegated or spotted initially.

Maintain consistent warm water temperature. Ensure adequate sunlight. Do not fertilize heavily yet; light feeding only.

3

Vegetative Growth

3-6 weeks

Mature floating leaves fully develop with characteristic deep green color. Plant increases in size with multiple leaves emerging regularly.

Begin balanced fertilization (aquatic plant fertilizer). Thin out excess leaves to prevent overcrowding and allow sunlight penetration. Water should remain 75-85°F.

4

Flowering

8-12 weeks (throughout warm season)

Deep crimson to red flower buds form and rise to the water surface. Blooms open during morning hours and close by afternoon or evening.

Maintain consistent deep red water color by continuing fertilization. Flowers appear in succession over the growing season. Remove spent blooms to encourage additional flowering.

5

Peak Production & Decline

4-8 weeks

Plant reaches maximum flowering with multiple blooms over several weeks. As water cools in fall, flowering slows and plant prepares for dormancy.

Continue maintenance but reduce fertilization as water temperatures drop below 75°F. Prepare to move plant indoors or drain pond if in cooler climates. Remove dead foliage.

Companion Planting

Plan your garden →

Plant with:

Avoid planting near:

Aggressive floating plants (water lettuce, azolla) that shade the lily Plants requiring acidic conditions if using lime in water Cold-hardy water lilies in the same warm water basin (different temperature needs)

Common Pests

  • Spray undersides of leaves with organic insecticidal soap; remove severely infested leaves; introduce natural predators like dragonflies

  • Reduce plant crowding for air circulation; spray with neem oil or insecticidal soap; remove damaged foliage

  • Ensure proper water circulation and avoid stagnant water; remove infected tissue; use fungicide if needed; maintain warm, clean water

  • Spray leaves with strong water jet or insecticidal soap; beneficial insects like ladybugs help; submerge leaves temporarily to drown aphids

Harvest Tips

Water lilies are ornamental; harvest by cutting flower stems just below the bloom with a sharp knife for floral arrangements. Cut early in the morning when blooms first open. Flowers last 3-4 days in a vase with fresh water. Remove spent flowers from the pond to encourage continued blooming and prevent rot.

Fun Facts

  • 🌱 Ellisiana is a hybrid cultivar developed by horticulturists and is not found in nature; it combines traits from multiple water lily species to achieve its distinctive deep red coloring.
  • 🌱 Water lilies can only be fertilized in the water they grow in because their roots absorb nutrients directly from the water column, unlike terrestrial plants.
  • 🌱 The flowers of Ellisiana water lily are thermogenic, meaning they generate heat to attract pollinators and help pollen develop properly.
