If you’ve been dreaming of adding some aquatic elegance to your garden pond, James’ waterlily (Nymphaea jamesoniana) might just catch your eye. This non-native perennial brings a touch of tropical charm to water features across Florida and Puerto Rico, where it has successfully established itself in the wild.


What is James’ Waterlily?
James’ waterlily is a perennial aquatic forb – essentially an herbaceous plant that lacks woody stems and thrives in water. Originally hailing from South America, this waterlily has made itself at home in warmer parts of the United States. You might also see it listed under its botanical synonyms Castalia jamesoniana or the illegitimate name Nymphaea blanda.
Where Does It Grow?
Currently, you’ll find James’ waterlily flourishing in Florida and Puerto Rico, where it has become a naturalized resident. As a non-native species, it reproduces on its own in the wild and tends to stick around once established.
The Appeal of James’ Waterlily
What makes this waterlily special? Here’s what draws gardeners to this aquatic beauty:
- Fragrant white to pale pink flowers that open during daylight hours
- Classic round, floating leaves that create that quintessential pond aesthetic
- Reliable blooming throughout the warm season
- Attracts bees, flies, and other pollinators to your water feature
Growing Conditions and Care
James’ waterlily is definitely a plant with specific needs – it’s classified as an Obligate Wetland species, meaning it almost always requires wetland conditions to thrive. Here’s what you need to know:
Ideal Growing Conditions
- Water requirements: Still or slow-moving freshwater bodies
- Light: Full sun to partial shade
- Climate zones: USDA zones 9-11 (warm, subtropical to tropical areas)

Planting and Maintenance Tips
Successfully growing James’ waterlily requires attention to its aquatic nature:

- Remove spent flowers and yellowing leaves to maintain plant health
- Provide protection from strong currents or wave action
Should You Plant James’ Waterlily?
While James’ waterlily isn’t listed as invasive or noxious, it is a non-native species that has naturalized in some areas. If you’re looking to create a stunning water garden, it can certainly deliver the classic waterlily look you’re after. However, if you prefer supporting native ecosystems, consider these native alternatives:
- American white waterlily (Nymphaea odorata)
- Banana waterlily (Nymphaea mexicana) – native to southern regions
- Various native Nymphaea species appropriate to your specific region

Just remember – this is definitely a plant that needs its feet wet (or completely submerged) to be happy!
