Cheesman’s Swallow-wort: A Caribbean Native Worth Knowing
If you’re gardening in the Caribbean or other tropical regions, you might be interested in discovering some lesser-known native gems. Meet Cheesman’s swallow-wort (Cynanchum cheesmanii), a charming perennial that calls Puerto Rico and the U.S. Virgin Islands home.
What Makes This Plant Special?
Cheesman’s swallow-wort is a true Caribbean native, belonging to the milkweed family (Apocynaceae). This perennial forb herb grows without developing woody stems, making it a perfect addition to herbaceous borders and naturalistic plantings. Unlike shrubs or trees, this plant maintains its soft, non-woody character throughout its life.
You might also encounter this plant under its former scientific names, Metastelma decipiens or Metastelma fallax, as botanical classifications have evolved over time.
Where Does It Grow Naturally?
This delightful native species is found exclusively in Puerto Rico and the U.S. Virgin Islands, making it a true regional specialty. If you’re gardening in these areas, you have the opportunity to grow a plant that’s perfectly adapted to your local climate and ecosystem.
Why Consider Growing Cheesman’s Swallow-wort?
There are several compelling reasons to include this native plant in your Caribbean garden:
- Native credentials: Supporting local ecosystems by choosing plants that evolved in your region
- Pollinator potential: As a member of the milkweed family, it likely provides nectar for local butterflies and other pollinators
- Regional authenticity: Adds genuine Caribbean character to your landscape
- Perennial reliability: Returns year after year once established
Growing Conditions and Care
Since Cheesman’s swallow-wort is native to the Caribbean, it’s best suited for tropical and subtropical climates, likely thriving in USDA hardiness zones 10-11. If you’re gardening outside these areas, this plant probably isn’t the right choice for your climate.
Given its native habitat, this plant likely prefers:
- Warm, tropical temperatures year-round
- Well-draining soils typical of Caribbean islands
- Humidity levels common to its native range
- Protection from strong winds that can damage herbaceous plants
Garden Design Ideas
Cheesman’s swallow-wort works beautifully in several garden settings:
- Native plant gardens: Perfect for authentic Caribbean landscapes
- Butterfly gardens: Its milkweed family connections make it a natural choice
- Naturalistic plantings: Blends well with other regional natives
- Educational gardens: Great for showcasing local plant heritage
A Word About Availability
As with many native plants, especially those with limited geographic ranges, Cheesman’s swallow-wort might not be readily available at your typical garden center. You may need to seek out specialty native plant nurseries or botanical organizations in Puerto Rico or the Virgin Islands.
If you’re interested in growing this plant, consider connecting with local native plant societies or botanical gardens that might have seeds or plants available through ethical collection and propagation programs.
The Bottom Line
Cheesman’s swallow-wort represents the kind of regional treasure that makes native plant gardening so rewarding. While it’s not a flashy showstopper, it offers the quiet satisfaction of growing something that truly belongs in your landscape. If you’re gardening in its native range and can source it responsibly, this little-known native deserves a spot in your Caribbean garden.
Remember, choosing native plants like Cheesman’s swallow-wort helps preserve local plant communities and supports the wildlife that depends on them. It’s a small but meaningful way to garden in harmony with your local ecosystem.
