Jackass Breadnut: A Hidden Gem of Caribbean Native Gardening
If you’re looking to add authentic Caribbean character to your garden in Puerto Rico or the U.S. Virgin Islands, you might want to get acquainted with jackass breadnut (Clibadium erosum). This native shrub may not be the flashiest plant at the garden center—in fact, you probably won’t find it there at all—but it represents the kind of authentic, locally-adapted vegetation that truly belongs in Caribbean landscapes.
What is Jackass Breadnut?
Jackass breadnut is a perennial shrub that’s part of the sunflower family (Asteraceae). Like many shrubs, it’s a multi-stemmed woody plant that typically stays under 13-16 feet tall, though it can grow taller or even single-stemmed depending on where it’s growing. Think of it as a medium-sized backdrop plant rather than a showstopper specimen.
Where Does It Call Home?
This shrub is a true Caribbean native, naturally occurring in Puerto Rico and the U.S. Virgin Islands. When we say native, we mean it evolved here over thousands of years, making it perfectly adapted to local conditions, wildlife, and weather patterns. It’s not found naturally anywhere else in the world, making it a special piece of Caribbean botanical heritage.
The Wetland Connection
Here’s where jackass breadnut gets interesting from an ecological standpoint. It’s classified as a facultative wetland plant in the Caribbean, which is a fancy way of saying it usually likes wet feet but can tolerate drier conditions too. This makes it potentially valuable for:
- Rain gardens and bioswales
- Areas with seasonal flooding
- Transition zones between wet and dry areas
- Natural stormwater management
Should You Plant Jackass Breadnut?
Here’s the honest truth: jackass breadnut is one of those plants that’s more important ecologically than horticulturally. If you’re passionate about native plant gardening and supporting local ecosystems, this shrub deserves consideration. However, if you’re looking for detailed growing guides, colorful blooms, or proven garden performance, you might be disappointed by the lack of available information.
Reasons to consider it:
- It’s authentically native to your region
- Likely supports local wildlife (though specific benefits aren’t well-documented)
- Adapted to local climate extremes
- Could work well in wet or periodically flooded areas
- Helps preserve local plant diversity
Challenges to consider:
- Very limited availability in nurseries
- Minimal cultivation information available
- Unknown ornamental qualities
- May require seed collection from wild populations
Growing Jackass Breadnut: What We Know
Unfortunately, detailed growing information for jackass breadnut is scarce. What we can infer from its native habitat and wetland status:
Likely growing conditions:
- Tolerates wet to seasonally wet soils
- Probably handles Caribbean heat and humidity well
- May prefer partial shade to full sun

USDA Hardiness Zones: Given its Caribbean native range, it’s likely suited for zones 10-11, possibly zone 9b with protection.
Finding and Planting Jackass Breadnut
This is where things get tricky. You’re unlikely to find jackass breadnut at your local nursery. If you’re serious about growing this native shrub, you might need to:
- Contact native plant societies in Puerto Rico or the U.S. Virgin Islands
- Work with local botanists or conservation groups
- Participate in native plant seed swaps or collection events
