Key Benefits of Mimosa Trees
Fast-Growing Shade
Mimosa trees are well known for their rapid growth, often reaching 20–35 feet tall and spreading into a soft, umbrella-like canopy within a few seasons. Their airy, dappled shade keeps patios cooler through evapotranspiration, all while allowing enough light underneath for flowering annuals, Catmint, Salvia, or shade annuals to thrive.
