Antilles Bean: A Caribbean Native with Limited Garden Information
Meet the Antilles bean (Vigna antillana), a perennial flowering plant that calls the beautiful Caribbean islands home. While this legume might not be as well-known as its cousins in the bean family, it has an interesting story to tell about island plant life and the challenges of growing lesser-known native species.
What is the Antilles Bean?
The Antilles bean is a perennial forb—basically a non-woody plant that comes back year after year. Unlike trees or shrubs, this plant doesn’t develop thick, woody stems above ground. Instead, it maintains its growing points at or below the soil surface, allowing it to regenerate each growing season. You might also see it listed under its scientific synonym, Phaseolus antillanus, in older botanical references.
Where Does It Grow?
This plant has a pretty exclusive address—it’s native to Puerto Rico and has naturalized in the U.S. Virgin Islands. In Puerto Rico, it’s considered a true native, while in the Virgin Islands, it’s established itself as a non-native species that reproduces on its own without human help.
Should You Grow Antilles Bean in Your Garden?
Here’s where things get a bit tricky. While the Antilles bean isn’t listed as invasive or noxious, there’s remarkably little information available about growing this particular species. This lack of cultivation information presents some challenges for the home gardener:
- Specific growing requirements are not well-documented
- Seeds or plants may be difficult to source
- Mature size and growth habits are unclear
- Pollinator and wildlife benefits are unknown
Growing Conditions and Care
Based on its native Caribbean habitat, the Antilles bean likely thrives in:
- Warm, tropical to subtropical climates (probably USDA zones 10-11)
- Well-draining soils
- Adequate moisture without waterlogging
- Full to partial sun exposure
However, without specific cultivation studies or gardener experiences, these are educated guesses based on its geographic origins rather than proven growing advice.
Alternative Options
If you’re interested in growing Caribbean native legumes but want more reliable information and plant sources, consider researching other native Vigna species or well-established native beans from your specific region. Your local native plant society or agricultural extension office can point you toward native legumes with better-documented growing requirements and available plant sources.
The Bottom Line
The Antilles bean represents one of those fascinating but frustrating aspects of native plant gardening—a species that’s botanically interesting but practically challenging due to limited cultivation information. While it’s not problematic to grow (no invasive or noxious status), the lack of specific growing guidance makes it a risky choice for most gardeners.
If you’re determined to work with this species, connect with botanical gardens or research institutions in Puerto Rico or the Virgin Islands, as they may have more experience with its cultivation needs. For most gardeners, however, focusing on better-documented native legumes will provide more reliable and rewarding results.
