Aquilon (Neolaugeria resinosa): A Rare Puerto Rican Native Worth Discovering

If you’re a plant enthusiast who loves discovering hidden gems in the botanical world, let me introduce you to aquilon (Neolaugeria resinosa). This intriguing Puerto Rican native might not be the showiest plant in your garden, but it represents something special – a piece of Caribbean botanical heritage that deserves more attention.

What is Aquilon?

Aquilon is a perennial shrub that’s endemic to Puerto Rico, meaning you won’t find it growing naturally anywhere else in the world. Like most shrubs, it’s a multi-stemmed woody plant that typically stays under 13-16 feet tall, though it can occasionally grow taller under the right conditions.

Botanically speaking, this plant has had a bit of an identity crisis over the years. You might also see it referenced by its older names, Laugeria resinosa or Terebraria resinosa, but Neolaugeria resinosa is the current accepted name.

Where Does Aquilon Grow?

This Caribbean native calls Puerto Rico home exclusively. In its natural habitat, aquilon tends to favor upland areas rather than wetlands, though it can occasionally tolerate wetter conditions. This flexibility suggests it might be more adaptable to different garden situations than you’d initially expect.

  • No observations

Why Consider Growing Aquilon?

Here’s where things get interesting – and a bit challenging. Aquilon is what we might call a mystery plant in the gardening world. While we know it’s a legitimate native species with a respectable shrub growth habit, detailed information about its appearance, growing requirements, and garden performance is surprisingly scarce.

This rarity could be both a blessing and a challenge for gardeners:

  • Conservation value: Growing native plants helps preserve local ecosystems and supports indigenous wildlife
  • Uniqueness factor: You’d have one of the most unusual plants in your neighborhood
  • Adaptation advantage: As a Puerto Rico native, it’s naturally suited to Caribbean growing conditions

The Growing Challenge

Here’s where I need to be honest with you – specific growing information for aquilon is virtually non-existent in gardening literature. This isn’t necessarily because it’s difficult to grow, but rather because it seems to be rarely cultivated.

Based on its native status and wetland classification as Facultative Upland, we can make some educated guesses about its preferences:

  • Likely thrives in USDA zones 11-12 (typical for Puerto Rico)
  • Probably prefers well-draining soil but can tolerate occasional moisture
  • As a tropical native, likely needs warm temperatures year-round
  • May benefit from partial shade during the hottest part of the day

Should You Plant Aquilon?

If you’re gardening in Puerto Rico or a similar tropical climate, aquilon could be a fascinating addition to a native plant collection. However, the biggest challenge will be finding it. This appears to be one of those plants that exists more in botanical records than in garden centers.

If you do manage to source aquilon, make sure it comes from reputable, sustainable sources. Given its rarity in cultivation, wild collection should be avoided to protect natural populations.

Alternative Native Options

If aquilon proves impossible to find, consider exploring other Puerto Rican native shrubs that might offer similar benefits with better availability. Your local native plant society or botanical garden can be excellent resources for discovering what’s actually available in your area.

The Bottom Line

Aquilon represents the fascinating world of lesser-known native plants – species that play important roles in their ecosystems but haven’t made the leap to mainstream horticulture. While it might not be the easiest plant to grow or find, it serves as a reminder that there’s still so much to discover in the plant kingdom, sometimes right in our own backyards.

For the adventurous gardener willing to work with limited information and potentially hard-to-find plants, aquilon offers the chance to grow something truly unique while supporting Caribbean plant conservation.

Neolaugeria resinosa is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Neolaugeria resinosa is also known as:

Laugeria resinosa | USDA symbol: LARE3
Terebraria resinosa | USDA symbol: TERE4

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.

Wetland Status

The rule of seasoned gardeners and landscapers is to choose the "right plant for the right place" — matching plants to their ideal growing conditions, so they'll thrive with less care and fewer inputs. But the simplicity of this catchphrase conceals how tricky plant selection can be if you don't have the right information. While tags on nursery plants list watering requirements, there's more to the story.

Knowing a plant's wetland status can simplify the process by revealing the interaction between plants, water, and soil. You might be surprised to learn that popular landscape plants are wetland species! And what may be a wetland plant in one area, in another it might thrive in drier conditions. The table below gives insight into the preferred growing conditions of this plant throughout its geographical distribution.
