Growth Stages

1

Rhizome Dormancy

Winter months, varies by zone

Plant exists as a dormant rhizome before warming water temperatures trigger growth.

Store rhizomes in cool, moist conditions over winter if in cold zones; keep above freezing.

2

Sprouting

2-4 weeks after planting

First leaves emerge and unfurl at water surface as water temperature reaches 60°F.

Ensure water remains clear and free of debris; begin light fertilization with aquatic fertilizer tablets.

3

Vegetative Growth

4-8 weeks

Plant produces multiple small lily pads that float or remain submerged; foliage establishes across container.

Apply aquatic fertilizer every 2-3 weeks; remove any algae or excess growth to prevent competition.

4

Flowering

6-10 weeks through summer and early fall

Small white flowers bloom just above water surface; blooms open in morning and close by afternoon.

Deadhead spent flowers to encourage more blooms; maintain water quality and temperature.

5

Senescence & Dormancy

Fall through winter

Growth slows as water cools in fall; foliage yellows and plant prepares for dormancy.

Reduce or stop fertilizing; in cold zones, move container to protected location or allow plant to winter over if hardy in your zone.

Harvest Tips

Cut flower blooms in early morning when fully open; use sharp scissors to cleanly sever the flower stem at water level. Flowers last 3-4 days in a vase.

Fun Facts

  • 🌱 Pygmaea Alba is one of the smallest water lily cultivars, making it perfect for even the tiniest water gardens—some gardeners grow them successfully in large ceramic bowls.
  • 🌱 Water lilies have evolved to close their flowers in the afternoon and at night, a behavior called nyctinasty, which protects the flower from nocturnal insects and moisture.
  • 🌱 The miniature lily pad leaves are so efficient at photosynthesis that a single plant can oxygenate and help maintain water quality in a small pond, benefiting fish and other aquatic organisms.
