The Story
Plant Bio
Nymphaea odorata is an aquatic perennial herb characterized by flat, circular green leaves that float on the water surface from creeping horizontal rhizomes. Highly fragrant, cup-shaped white flowers with prominent golden-yellow centers open during the day and close at night throughout the warmer months.
The glossy leaves feature a deep, narrow V-shaped cleft to the center and often display reddish or purplish undersides on new growth. Individual rhizome systems spread three to five feet wide, forming dense floating mats in still freshwater environments.

Planting
How to Grow
- Select a heavy, mineral-rich clay or organic loam soil and fill a wide, shallow aquatic planting container.
- Plant the horizontal rhizome at a slight angle with the growing tip exposed just above the soil surface, covering the soil with a layer of pea gravel to prevent fish from disturbing the roots.
- Submerge the container slowly into still freshwater, keeping the crown 12 to 48 inches below the surface.
- Position the container in a location receiving at least five to six hours of direct daily sunlight to ensure robust flowering.
Pro Tip
Press specialized slow-release aquatic fertilizer tablets deep into the soil surrounding the rhizome rather than broadcasting nutrients into the water column, which triggers aggressive algae blooms.

Care Guide
Do
- Cut back yellowing leaves and spent flower stems to the base of the plant regularly to prevent organic rot.
- Use heavy clay or loam rather than standard potting mixes, which float and cloud the water.
- Keep the planting depth between 12 and 48 inches of non-turbid, still water.
Don't
- Do not allow the rhizomes to dry out during propagation or transplanting, as they desiccate rapidly.
- Do not plant in fast-moving or highly turbulent water, which disrupts leaf and flower development.
- Do not fertilize with standard garden fertilizers; use only specialized slow-release aquatic tablets.
