Cascabelillo Axilar: A Caribbean Native Shrub Worth Discovering
If you’re gardening in the Caribbean or other tropical locations, you might want to get acquainted with cascabelillo axilar (Crotalaria lotifolia). This delightful native shrub brings both beauty and ecological value to warm-climate gardens, though it’s definitely not a plant you’ll find at your typical garden center.
What Is Cascabelillo Axilar?
Cascabelillo axilar goes by the botanical name Crotalaria lotifolia, and it’s a true Caribbean native. This perennial shrub is part of the legume family, which means it has those characteristic pea-like flowers that pollinators absolutely adore. As a multi-stemmed woody plant, it typically stays under 13-16 feet tall, making it a manageable size for most garden spaces.
Where Does It Come From?
This lovely shrub calls Puerto Rico and the U.S. Virgin Islands home. It’s a genuine native to these Caribbean islands, which means it has evolved alongside the local wildlife and climate conditions over thousands of years. When you plant cascabelillo axilar, you’re not just adding a pretty shrub to your garden – you’re supporting the local ecosystem.

There are several compelling reasons to give this native shrub a spot in your tropical garden:
