Parasita (Vriesea macrostachya): A Mysterious Puerto Rican Native
Meet parasita, a little-known native plant that calls Puerto Rico home. With the botanical name Vriesea macrostachya, this perennial belongs to the fascinating bromeliad family – the same group that gives us pineapples and those dramatic air plants you see in trendy plant shops.

What Makes Parasita Special?
Parasita is what botanists call a forb, which simply means it’s a soft-stemmed, herbaceous plant without woody growth above ground. Think of it as the plant world’s version of a gentle soul – it relies on its underground parts to survive year after year rather than building tough, woody stems like trees and shrubs.
This native Puerto Rican species also goes by the synonym Neovriesia macrostachya, though you’re unlikely to encounter either name at your local garden center anytime soon.
Where Does Parasita Call Home?
Parasita is exclusively found in Puerto Rico, making it a true island endemic. This means it evolved specifically in Puerto Rico’s unique environment and doesn’t naturally occur anywhere else in the world.
The Challenge of Growing Parasita
Here’s where things get tricky for gardening enthusiasts. Parasita appears to be an extremely rare or poorly documented species, with very little information available about its specific needs, appearance, or cultivation requirements. This presents several important considerations:
- Limited availability: You’re unlikely to find this plant in nurseries or seed catalogs
- Unknown growing requirements: Without detailed information about its natural habitat preferences, successful cultivation would be largely guesswork
- Conservation concerns: Rare native plants should only be grown from responsibly sourced material to avoid impacting wild populations
What This Means for Your Garden
While the mysterious nature of parasita makes it an intriguing conversation piece, it’s not a practical choice for most gardeners. The lack of cultivation information, combined with its apparent rarity, means you’d be better served exploring other Puerto Rican native bromeliads that are better understood and more readily available.
If you’re passionate about supporting Puerto Rican native plants in your garden, consider researching other documented native species that can provide similar ecological benefits with greater certainty of success.
The Bigger Picture
Parasita serves as a reminder of how much we still don’t know about our native flora. Many endemic species remain poorly studied, existing quietly in their natural habitats without fanfare or recognition. While we can’t all grow every rare native plant, we can support conservation efforts and botanical research that help protect these mysterious species for future generations.
Sometimes the most responsible approach to loving native plants is simply appreciating them from afar while focusing our gardening efforts on well-documented species that we know we can grow successfully.
