Growth Stages

1

Dormancy/Planting

2-3 weeks

Rhizome is planted in soil; minimal visible growth as root system establishes

Use heavy soil in a planting container; ensure water temperature is warming (60°F+) before planting; fertilize weekly with aquatic plant tablets

2

Vegetative Growth

3-4 weeks

Leaves emerge from the rhizome and float or extend above water surface; plant develops multiple growth shoots

Remove any damaged leaves; ensure adequate sunlight; continue weekly fertilization; maintain consistent water level

3

Budding

1-2 weeks

Flower buds form at leaf axils and begin to swell; buds rise to water surface

Maintain steady water temperature and sunlight; increase fertilization if available; avoid water turbulence that may damage emerging buds

4

Flowering

4-6 months (June-September in northern zones)

Blooms open in morning and close in afternoon; flowers are star-shaped in pink or red with yellow centers; may produce 4-6 flowers simultaneously

Deadhead spent flowers to encourage continuous blooming; maintain water quality; ensure 6+ hours of direct sun daily for maximum bloom production

5

Late Season/Dormancy Preparation

6-8 weeks

As water cools in fall, flowering slows; foliage may yellow or decline; rhizome prepares for dormancy

In zones 5-8, move containers to deep water (3+ feet) or indoors before frost; in warmer zones, may remain evergreen; reduce fertilization

Companion Planting

Plan your garden →

Plant with:

Avoid planting near:

Aggressive emergent plants like common cattails (Typha latifolia) that compete for nutrients Fast-growing algae-promoting shallow water plants without circulation Plants that require frequent pesticide application (incompatible with aquatic ecosystems)

Common Pests

  • Hand-pick affected leaves; spray neem oil or insecticidal soap weekly; ensure fish or frogs are present to control larvae in ponds

  • Rinse leaves with strong water spray; apply insecticidal soap; introduce ladybugs or fish predators; avoid systemic insecticides in enclosed water systems

  • and

    Introduce fish (koi, goldfish) that eat larvae; manually remove snails; maintain good water circulation and aeration

  • Ensure proper soil drainage and aeration; use sterile planting medium; avoid overfertilizing; keep water quality optimal with regular changes

Fun Facts

  • 🌱 Graziella water lilies are one of the smallest cultivated water lily varieties, making them perfect for container gardens and aquariums where full-size varieties would overwhelm the space.
  • 🌱 Unlike some water lilies, Graziella blooms remain open for an extended period during the day (typically 9 AM - 4 PM), making them more reliably visible than night-blooming varieties.
  • 🌱 Water lilies have been cultivated and revered for over 5,000 years, appearing in ancient Egyptian art and hieroglyphics; they were sacred to Egyptians and symbolized rebirth and the sun god Ra.
