Redmammee: A Critically Endangered Treasure of Puerto Rico

Meet the redmammee (Pouteria hotteana), one of Puerto Rico’s most endangered native trees and a true botanical treasure that’s teetering on the edge of extinction. This remarkable species represents both the incredible biodiversity of the Caribbean and the urgent need for plant conservation efforts.

What Makes Redmammee Special?

Redmammee is a perennial tree native exclusively to Puerto Rico, making it what botanists call an endemic species. As a member of the Sapotaceae family, it shares lineage with other tropical fruits like sapodilla, but this particular species has evolved to thrive only in Puerto Rico’s unique ecosystem.

This striking tree typically grows as a single-stemmed specimen reaching heights of 13 to 16 feet or more, with glossy, leathery leaves that catch the tropical light beautifully. Under certain environmental conditions, it may develop a shorter, multi-stemmed growth form.

Geographic Distribution and Conservation Status

Redmammee grows naturally only in Puerto Rico, where it has become critically imperiled. The species currently holds a Global Conservation Status of S1, meaning it’s critically imperiled due to extreme rarity. Scientists estimate there are typically only 5 or fewer occurrences of this species in the wild, with fewer than 1,000 individual plants remaining.

Should You Plant Redmammee?

Important Conservation Note: Due to its critically endangered status, redmammee should only be planted using responsibly sourced material from legitimate conservation programs or botanical institutions. Never collect this plant from the wild, as doing so could push this rare species closer to extinction.

If you can source redmammee through proper conservation channels, here’s why it might be worth considering:

  • You’ll be participating in crucial conservation efforts
  • It serves as a unique specimen tree with significant botanical importance
  • Perfect for specialized tropical gardens focused on native Caribbean flora
  • Contributes to preserving Puerto Rico’s endemic plant heritage

Growing Conditions and Care

Given its Puerto Rican origins, redmammee thrives in tropical conditions similar to USDA hardiness zones 10-11. While specific growing requirements aren’t well-documented due to the species’ rarity, most Caribbean endemic trees prefer:

  • Well-draining, fertile soil
  • Consistent warmth and humidity
  • Protection from strong winds
  • Partial shade to full sun exposure

Landscape Role and Design Applications

Redmammee works best as a specimen tree in specialized settings such as:

  • Botanical gardens and arboreta
  • Conservation-focused landscapes
  • Educational gardens highlighting Caribbean biodiversity
  • Specialized tropical plant collections

Planting and Care Tips

If you’re fortunate enough to obtain redmammee through legitimate conservation sources:

  • Plant in a protected location away from foot traffic
  • Ensure excellent drainage to prevent root rot
  • Provide consistent moisture without waterlogging
  • Consider joining or supporting conservation organizations working to preserve this species
  • Document your plant’s growth and health for conservation records

The Bigger Picture

Growing redmammee isn’t just about adding an unusual plant to your garden—it’s about participating in conservation history. Every responsibly grown redmammee represents hope for this species’ survival and contributes to maintaining the rich botanical heritage of Puerto Rico.

While this tree may not be suitable for every garden due to its rarity and specific needs, those passionate about plant conservation and tropical botany will find redmammee to be an incredibly meaningful addition to their collection. Just remember: with great botanical rarity comes great responsibility!
