19. Switchgrass
Grasses are a welcoming asset to any garden, especially for those that are stuck in desert-like places. Indigenous prairie grasses, in particular, reach deep into the soil with their roots preventing erosion and aiding in soil drainage.
As a native of American tallgrass prairies, a flower, rock, or succulent garden with Switchgrass will immediately evoke the majesty and endless vistas of the meadows. It is also a fascinating plant that is being researched for biofuel, plastics, and more making it a potentially amazing crop for the future!
