Thinleaf Camasey: A Rare Caribbean Treasure Worth Protecting
Meet the thinleaf camasey (Henriettea membranifolia), one of Puerto Rico’s most precious and endangered native shrubs. While most gardening blogs focus on plants you should grow, this one’s about a plant that’s so rare, you probably shouldn’t—unless you’re part of a serious conservation effort.
What Makes Thinleaf Camasey Special?
The thinleaf camasey is a perennial shrub that’s found exclusively in Puerto Rico, making it what botanists call an endemic species. This multi-stemmed woody plant typically grows to heights of 13-16 feet, though it can vary depending on environmental conditions. Like many Caribbean natives, it’s adapted to life in a tropical paradise—but unfortunately, paradise isn’t always permanent.
A Plant on the Brink
Here’s where things get serious: the thinleaf camasey has a Global Conservation Status of S1, which means it’s critically imperiled. In plain English? There are likely only five or fewer populations left in the wild, with fewer than 1,000 individual plants total. That makes this shrub rarer than many animals you’d find in a zoo.
Where Does It Call Home?
This rare beauty is native exclusively to Puerto Rico, where it clings to existence in increasingly fragmented habitats. Its distribution is limited to this single Caribbean island, making every remaining plant incredibly precious.

Living Life in the Wetlands
The thinleaf camasey is classified as a facultative wetland plant in the Caribbean region. This means it usually prefers wetland environments but can sometimes tolerate drier conditions. Think of it as a plant that likes to keep its feet wet but won’t necessarily throw a tantrum if the soil dries out occasionally.
Should You Grow Thinleaf Camasey?
Here’s the honest answer: probably not. Given its critically imperiled status, the thinleaf camasey should only be cultivated by:
- Botanical gardens with conservation programs
- Research institutions
- Certified conservation nurseries
- Serious collectors working with responsibly sourced, legally obtained material
If you’re a home gardener in Puerto Rico or a similar climate zone (USDA zones 10-11), there are plenty of other native alternatives that would love a spot in your garden without contributing to the decline of a critically rare species.
What We Can Do Instead
Rather than trying to grow this rare gem, consider these conservation-friendly alternatives:
- Support local botanical gardens and conservation organizations
- Choose other native Puerto Rican plants that aren’t critically endangered
- Learn about and advocate for habitat protection
- If you’re in a position to contribute to conservation efforts, consider supporting research and protection of remaining populations
The Bigger Picture
The story of the thinleaf camasey is a reminder that not every beautiful native plant is meant for our gardens. Sometimes, the most loving thing we can do is admire from afar and work to protect what little remains in the wild. In a world where we’re losing biodiversity at an alarming rate, every critically imperiled species like Henriettea membranifolia represents a piece of our planet’s natural heritage that, once lost, can never be replaced.
So while you might not be planting thinleaf camasey in your backyard, you can still be part of its story by supporting conservation efforts and choosing other native plants that will thrive in cultivation while leaving the rarest species to recover in their natural homes.
