Garden Puff: A Charming Native Wetland Shrub for Tropical Gardens
Meet the garden puff (Neptunia prostrata), a delightful native shrub that’s perfect for gardeners looking to create authentic wetland landscapes in tropical climates. This charming perennial brings both beauty and ecological value to water gardens, making it a fantastic choice for specialized garden settings.
What Makes Garden Puff Special
Garden puff is a native treasure of Puerto Rico, where it naturally thrives in wetland environments. Also known by its botanical name Neptunia prostrata, this perennial shrub produces adorable pink to purple puff-ball flowers that look like tiny fireworks bursting from delicate, feathery foliage. The compound leaves have a fascinating feature – they fold up when touched, adding an interactive element that delights both children and adults.
As a multi-stemmed woody shrub, garden puff typically stays under 13-16 feet in height, making it a manageable size for most garden settings. Its spreading growth habit allows it to naturalize beautifully in appropriate conditions.
Where Garden Puff Grows
This native beauty is found naturally in Puerto Rico, where it plays an important role in local wetland ecosystems. Its distribution is quite limited, making it a special addition for gardeners within its natural range.
Perfect Growing Conditions
Garden puff is what botanists call an obligate wetland plant in most regions, meaning it almost always occurs in wetlands. Here’s what this water-loving shrub needs to thrive:
- Moisture: Consistently wet to moist soil conditions
- Light: Full sun to partial shade
- Climate: USDA zones 10-11 only (tropical and subtropical)
- Soil: Tolerates various soil types as long as they stay wet
- Water tolerance: Can handle periodic flooding

- Water garden perfect: Ideal for pond edges, rain gardens, and bog gardens

Planting and Care Tips
Success with garden puff depends on meeting its water requirements:

Is Garden Puff Right for You?
Garden puff is perfect for gardeners in tropical climates (zones 10-11) who have consistently wet areas to fill. It’s particularly valuable for those creating authentic native landscapes or working on wetland restoration projects. However, it’s not suitable for typical garden beds or areas that experience dry periods.
If you’re outside its natural range or don’t have appropriate wetland conditions, consider other native wetland plants suited to your specific region and climate zone.
For the right gardener in the right location, garden puff offers a unique combination of beauty, ecological value, and interactive charm that makes it a treasured addition to specialized water gardens.
