Amor Seco: A Charming Native Ground Cover for Puerto Rican Gardens
If you’re looking to add authentic Caribbean charm to your Puerto Rican garden, let me introduce you to amor seco (Desmodium affine). This delightful native perennial might not win any beauty contests, but it’s got personality in spades and offers some wonderful benefits for local gardeners who appreciate native plants.
What Exactly is Amor Seco?
Amor seco, scientifically known as Desmodium affine, is a native Puerto Rican perennial that belongs to the legume family. As a forb, it’s essentially an herbaceous plant without woody stems – think of it as nature’s own ground-hugging carpet. You might also see it listed under its botanical synonym Meibomia affinis, but don’t let the name confusion fool you – it’s the same charming little plant.
Where You’ll Find This Native Gem
This plant calls Puerto Rico home, where it has adapted beautifully to the tropical climate and local growing conditions. As a true island native, it’s perfectly suited to the unique environmental conditions found in Puerto Rican landscapes.
Why Consider Amor Seco for Your Garden?
While amor seco may not be the showiest plant in your garden, it brings several compelling reasons to give it a spot in your landscape:
- It’s a true Puerto Rican native, supporting local ecosystem health
- Low maintenance once established
- Provides ground cover in naturalistic plantings
- Supports local pollinators with its small but meaningful flowers
- Drought tolerant after establishment
What Does Amor Seco Look Like?
Don’t expect dramatic blooms or flashy foliage – amor seco’s beauty lies in its understated charm. This perennial produces small compound leaves and delicate pink to purple flowers arranged in terminal clusters. The overall effect is subtle and naturalistic, making it perfect for gardeners who prefer plants that blend harmoniously into the landscape rather than demanding center stage.
Perfect Garden Situations for Amor Seco
This native plant shines in several garden scenarios:
- Native plant gardens focusing on Puerto Rican species

- Ground cover areas where you want something low-maintenance
- Pollinator gardens supporting local bee and butterfly populations
- Tropical-style gardens emphasizing authentic Caribbean plants
Growing Conditions and Care
As a Puerto Rican native, amor seco is naturally adapted to tropical conditions. Here’s what this easygoing plant prefers:
- Sunlight: Full sun to partial shade
- Soil: Well-draining soils (avoid waterlogged conditions)
- Climate: Thrives in USDA zones 10-11, perfect for Puerto Rico’s tropical climate
- Water: Drought tolerant once established, though regular watering helps during establishment
Planting and Care Tips
The beauty of growing native plants like amor seco is that they’re naturally adapted to local conditions, making your gardening life easier:
- Plant during the rainy season when natural moisture helps establishment
- Space plants appropriately to allow for natural spreading
- Water regularly during the first few months, then reduce as the plant establishes
- Minimal fertilization needed – as a legume, it can fix its own nitrogen
- Allow it to self-seed for natural expansion in suitable areas
- Very low maintenance once established
Supporting Local Wildlife
While we don’t have specific data on amor seco’s wildlife benefits, most Desmodium species support local pollinators through their flowers. As a native plant, it’s likely providing food and habitat for insects and other small wildlife that have evolved alongside it in Puerto Rico’s ecosystems.
Is Amor Seco Right for Your Garden?
Amor seco is an excellent choice if you’re passionate about native plants, want low-maintenance ground cover, or are creating habitat for local wildlife. However, it might not be the best fit if you’re looking for dramatic ornamental impact or need a plant for cooler climates outside of tropical zones.
As with any native plant, the key is sourcing it responsibly and giving it the growing conditions it naturally prefers. In the right spot, amor seco will reward you with years of understated beauty and the satisfaction of supporting Puerto Rico’s natural heritage in your own backyard.
