Fishlock’s Croton: A Rare Caribbean Treasure Worth Protecting
Meet Fishlock’s croton (Croton fishlockii), one of the Caribbean’s best-kept secrets – and by best-kept, I mean it’s so rare that most gardeners have never heard of it! This perennial shrub is a true island endemic, calling only the U.S. Virgin Islands home.


Where Does Fishlock’s Croton Come From?
Fishlock’s croton is native exclusively to the U.S. Virgin Islands, making it a true Caribbean endemic. You won’t find this special plant growing wild anywhere else in the world – talk about exclusive! This limited geographic distribution is part of what makes this species so special and, unfortunately, so vulnerable.
What Makes This Plant Special (And Rare)?
Here’s where things get serious: Fishlock’s croton has a Global Conservation Status of S2, which means it’s classified as Imperiled. This isn’t a designation we take lightly – it means the species is extremely rare, with typically only 6 to 20 known occurrences or between 1,000 to 3,000 remaining individuals. Some factors are making it especially vulnerable to disappearing forever.
As a perennial shrub, Fishlock’s croton is a multi-stemmed woody plant that typically stays under 13-16 feet tall. Like other shrubs, it usually has several stems growing from or near the ground, giving it that classic bushy appearance we love in landscape design.
Should You Plant Fishlock’s Croton?
Here’s the thing – while we’d love to encourage everyone to grow this unique native species, its rarity status means we need to be incredibly responsible. If you’re determined to grow Fishlock’s croton, please follow these important guidelines:
- Only source plants from reputable, ethical nurseries that propagate from legally obtained, responsibly sourced material
- Never collect plants or seeds from wild populations
- Consider supporting conservation efforts for this species instead of or in addition to growing it
- Work with local botanical gardens or conservation organizations if you’re interested in helping preserve this species
Growing Challenges and Considerations
Unfortunately, there’s limited information available about the specific growing requirements for Fishlock’s croton. This lack of cultivation knowledge is partly due to its rarity – there simply haven’t been enough plants in cultivation to develop detailed growing guides.
What we do know is that as a Virgin Islands native, it likely prefers tropical conditions similar to other Caribbean plants. However, without specific data about its preferred growing conditions, soil requirements, or care needs, successfully cultivating this plant would be quite challenging even for experienced gardeners.
Alternative Native Options
If you’re interested in supporting native plant conservation but want something more readily available, consider these alternatives:
- Look into other native plants from your specific region that are more commonly available
- Support native plant societies and botanical gardens working on rare species conservation
- Choose well-documented native species that provide known benefits to local wildlife and ecosystems
The Bottom Line
Fishlock’s croton represents the delicate balance between our desire to grow unique plants and our responsibility to protect rare species. While this Caribbean endemic is undoubtedly special, its imperiled status means that conservation should take priority over cultivation.
If you’re passionate about rare plants, consider channeling that enthusiasm into supporting conservation efforts, visiting botanical gardens that may have specimens, or learning more about plant conservation in general. Sometimes the best way to appreciate a rare plant is to help ensure it survives for future generations to discover and admire.
