Catalina Grass: A Lesser-Known Native Annual Grass Worth Discovering
If you’re on the hunt for native grasses to add authenticity to your California landscape, you might want to get acquainted with Catalina grass (Dissanthelium). This annual grass is one of those under-the-radar natives that doesn’t get much spotlight, but it has its own quiet charm for gardeners who appreciate the subtle beauty of our indigenous flora.
What Exactly Is Catalina Grass?
Catalina grass belongs to the graminoid family, which is a fancy way of saying it’s part of the grass and grass-like plant gang. As an annual, this little guy completes its entire life cycle in just one growing season – sprouting, growing, flowering, setting seed, and calling it a day all within a year.
What makes this grass special is its native status. It’s a true California native, naturally occurring in the Golden State as part of our region’s original plant community. When you plant Catalina grass, you’re essentially rolling out the welcome mat for a plant that has been calling California home long before any of us arrived on the scene.
Where Does It Grow?
Catalina grass has made California its exclusive stomping ground within the lower 48 states. This geographic specificity makes it a fantastic choice for gardeners who want to create landscapes that truly reflect their local ecosystem.
