Jacanillo: A Lesser-Known Puerto Rican Native Shrub Worth Discovering
If you’re on the hunt for authentic Caribbean native plants, you might have stumbled across jacanillo (Wallenia lamarckiana) in your research. This perennial shrub is a true Puerto Rican native that’s flying under the radar in most gardening circles – and honestly, that’s partly because there’s still so much we don’t know about this intriguing plant!
What Exactly Is Jacanillo?
Jacanillo is a multi-stemmed woody shrub that typically stays under 13-16 feet tall, making it a manageable size for most garden spaces. Like many shrubs, it usually develops several stems from ground level, creating that classic bushy appearance we gardeners love for adding structure to our landscapes.
You might also see this plant listed under its former names: Petesioides pendula or Wallenia pendula. Botanists do love to shuffle names around, don’t they?
Where Does Jacanillo Call Home?
This shrub is exclusively native to Puerto Rico, making it a true island endemic. If you’re gardening in Puerto Rico or trying to create an authentic Caribbean landscape, jacanillo represents the real deal – a plant that evolved specifically in this unique tropical environment.

The Mystery Plant: What We Know and What We Don’t
Here’s where jacanillo gets interesting – and a bit frustrating for us plant nerds. While we know it’s a legitimate native species, detailed information about its growing habits, appearance, and garden performance is surprisingly scarce. What we do know is that it has a facultative wetland status, meaning it’s adaptable enough to thrive in both wet and relatively dry conditions. That’s actually pretty promising for gardeners!
Should You Plant Jacanillo?
If you’re gardening in Puerto Rico or similar tropical zones (likely USDA zones 10-11), jacanillo could be an excellent choice for several reasons:
- It’s authentically native to your region
- Its facultative wetland status suggests it’s adaptable to various moisture conditions
- As a shrub, it can provide structure and screening in your landscape
- You’d be supporting biodiversity by growing a lesser-known native species
However, the limited available information means you’d essentially be pioneering its use in cultivation. That could be exciting if you’re up for some horticultural detective work!
Growing Conditions and Care
Given its Puerto Rican origins and facultative wetland status, jacanillo likely prefers:
- Warm, tropical conditions year-round
- Moderate to high humidity
- Well-draining soil that can handle occasional moisture fluctuations
- Protection from cold temperatures (probably not frost-tolerant)
Beyond these educated guesses based on its native habitat, specific care requirements remain something of a mystery. If you do decide to grow jacanillo, you’ll want to start with typical tropical shrub care and adjust based on how your plant responds.
The Bottom Line
Jacanillo represents both an opportunity and a challenge. For gardeners in Puerto Rico, it’s a chance to grow something truly native and potentially discover a garden gem that deserves more attention. The lack of detailed growing information means you’d be somewhat experimental in your approach, but that’s part of the adventure of working with lesser-known natives.
If you can source jacanillo from a reputable native plant provider, it could be a worthwhile addition to a tropical native garden. Just be prepared to learn as you go, and consider sharing your experiences with other gardeners – you might help fill in those knowledge gaps!
