False Mastic: A Hidden Gem for Coastal and Subtropical Gardens

If you’re looking for a native tree that combines beauty, resilience, and low maintenance, let me introduce you to the False Mastic (Sideroxylon foetidissimum). Don’t let that intimidating botanical name scare you away – this Caribbean and South Florida native is actually one of the most reliable trees you can add to your landscape, especially if you live in coastal areas.

What is False Mastic?

False Mastic is a perennial tree that’s truly native to American soil, specifically found in South Florida, Puerto Rico, the U.S. Virgin Islands, and Navassa Island. You might also see it listed under its synonym, Mastichodendron foetidissimum, but don’t worry – it’s the same wonderful tree!

This native beauty typically grows as a single-trunked tree reaching heights of 13 to 16 feet or more, though under certain conditions it may develop a more compact, multi-stemmed form. Its dense, rounded canopy creates excellent shade, making it a fantastic choice for both practical and aesthetic purposes.

Where Does False Mastic Grow?

False Mastic naturally thrives in Florida, Puerto Rico, the Virgin Islands, and Navassa Island. It’s perfectly adapted to the coastal and subtropical conditions of these regions, which gives you a clue about what this tree loves most.
