Like most shrubs, it’s a multi-stemmed woody plant that typically stays under 13-16 feet tall, though it can vary depending on growing conditions.

This native beauty calls the Caribbean home, specifically thriving in Puerto Rico and the U.S. Virgin Islands. It’s adapted to the tropical conditions of these islands, making it a perfect choice for gardeners in these regions who want to work with plants that naturally belong in their landscape.
Why Consider Bur Mallow for Your Garden?
Here’s the thing about bur mallow – it’s somewhat of a mystery plant in the gardening world. While there’s limited detailed information available about its specific growing habits and garden performance, there are several compelling reasons to consider it:
