Black Apple (Diospyros revoluta): A Rare Puerto Rican Native Worth Knowing About
If you’re passionate about native Caribbean plants or have connections to Puerto Rico’s unique flora, you might have stumbled across the intriguing black apple. This lesser-known member of the persimmon family represents one of Puerto Rico’s endemic treasures, though finding detailed growing information can be as elusive as the plant itself.
What is Black Apple?
Black apple (Diospyros revoluta) is a perennial tree native exclusively to Puerto Rico. As part of the Diospyros genus, it’s related to the familiar American persimmon and other ebony trees. True to its tree classification, black apple typically grows as a single-stemmed woody plant that can reach heights greater than 13-16 feet, though environmental conditions may sometimes result in shorter, multi-stemmed forms.
You might also encounter this species listed under its botanical synonym, Diospyros ebenaster auct. non Retz., in older botanical references.
Where Does Black Apple Grow?
This tree is found exclusively in Puerto Rico, making it a true endemic species. Its limited geographic distribution adds to both its uniqueness and the challenges of finding cultivation information.
Should You Grow Black Apple?
Here’s where things get tricky. While black apple would be an exceptional choice for native Puerto Rican landscaping or specialized tropical plant collections, several factors make it a challenging recommendation:
- Limited availability in the nursery trade
- Lack of documented growing requirements
- Potential rarity that may make wild collection inappropriate
- Uncertain hardiness outside its native range
The Information Gap Challenge
Unfortunately, detailed horticultural information about Diospyros revoluta is scarce. Unlike its better-known cousins in the persimmon family, black apple hasn’t been extensively studied or cultivated, leaving gardeners with more questions than answers about:
- Specific soil and water requirements
- Pollination needs and wildlife benefits
- Growth rate and mature size variations
- Propagation methods
- Pest and disease considerations
A Responsible Approach
If you’re interested in growing black apple, the responsible approach involves:
- Sourcing plants only from reputable native plant nurseries
- Never collecting from wild populations
- Contributing to conservation efforts if possible
- Connecting with Puerto Rican botanical institutions for guidance
