MacFadyen’s Camasey: A Rare Puerto Rican Native Worth Protecting

If you’re passionate about native plants and conservation gardening, MacFadyen’s camasey (Henriettea macfadyenii) might just capture your interest. This lesser-known Puerto Rican native tree represents the kind of unique biodiversity that makes island ecosystems so special – and so worth protecting.

What is MacFadyen’s Camasey?

MacFadyen’s camasey is a perennial tree native exclusively to Puerto Rico. As a member of the Melastomataceae family, it shares kinship with other tropical flowering trees, though this particular species remains relatively understudied in horticultural circles. True to its tree classification, mature specimens typically reach heights of 13-16 feet or more, developing the characteristic single trunk that distinguishes trees from shrubs.

Where Does It Grow?

This tree calls Puerto Rico home and appears nowhere else naturally in the world. Its limited distribution makes it a true island endemic – one of those special plants that evolved in isolation to become uniquely adapted to its specific environment.

A Conservation Consideration

Here’s where things get interesting (and important): MacFadyen’s camasey has a Global Conservation Status of S3?, indicating some level of uncertainty about its population status. While not definitively listed as endangered, this designation suggests the species deserves our attention and care.

If you’re considering adding this tree to your Puerto Rican garden, please ensure you source it responsibly. This means:

  • Purchasing only from reputable nurseries that propagate rather than wild-collect
  • Avoiding any temptation to collect seeds or cuttings from wild populations
  • Supporting conservation efforts when possible

Growing Conditions and Habitat Preferences

MacFadyen’s camasey has a wetland status of Facultative Wetland in the Caribbean region. This means it typically thrives in moist to wet conditions but can also tolerate drier sites. If you’re planning a rain garden, pond margin, or naturally moist area of your landscape, this tree might be a perfect fit.

Unfortunately, detailed cultivation information for this species remains limited. As with many rare native trees, growing requirements haven’t been extensively documented in horticultural literature.

Why Choose Native?

Planting native species like MacFadyen’s camasey offers several compelling benefits:

  • Supports local ecosystems and wildlife that evolved alongside these plants
  • Requires less maintenance once established, as it’s naturally adapted to local conditions
  • Helps preserve Puerto Rico’s unique botanical heritage
  • Contributes to conservation efforts for potentially vulnerable species

The Bottom Line

MacFadyen’s camasey represents the fascinating but fragile nature of island biodiversity. While information about cultivation remains limited, its status as a Puerto Rican endemic makes it a valuable addition to native plant gardens – provided it’s sourced responsibly.

If you can’t locate MacFadyen’s camasey from ethical sources, consider other native Puerto Rican trees that might offer similar ecological benefits while being more readily available through proper nursery channels. Your local native plant society or extension office can help point you toward alternatives that support the same conservation goals.

Remember: when it comes to rare native plants, sometimes the most loving thing we can do is admire them in their natural habitat while choosing more common natives for our gardens.
