Grasses are a welcome addition to any garden, especially for those living in desert-like environments. Prairie grasses, in particular, extend deep into the soil with their roots, avoiding erosion and improving drainage.
Switchgrass, a native of the American tallgrass grasslands, will quickly convey the majesty and endless views of the meadows in a flower, rock, or succulent garden. It's also a fascinating plant studied for biofuel, polymers, and other applications, making it a promising crop for the future!
