Hirtella: A Hidden Gem for Tropical Native Plant Gardens
If you’re gardening in the Caribbean or other tropical regions, you might want to get acquainted with hirtella (Hirtella). This charming native shrub has been quietly beautifying the landscapes of Puerto Rico and the U.S. Virgin Islands for centuries, and it’s about time more gardeners discovered its potential.

What Exactly Is Hirtella?
Hirtella is a perennial shrub that embodies the classic tropical understory plant. As a multi-stemmed woody plant, it typically grows to a manageable height of 13 to 16 feet, though it can sometimes stretch taller or remain more compact depending on growing conditions. What makes this plant particularly appealing is its bushy growth habit – several stems emerge from or near the ground, creating a full, natural-looking shrub that fits beautifully into tropical landscapes.
