Ornamental grasses have value in both functional and aesthetic gardening. They offer a unique combination of beauty, resilience, and low-maintenance charm. If you’re landscaping in tough conditions, such as hot, dry climates, these versatile plants have a lot to offer. 

Many ornamental grasses require little care, even under harsh conditions. They are ideal for poor or sandy soil types, and typically quite drought-resistant. They need little fertilizer, and usually only one pruning per year (an annual cutback). They’re also great for preventing erosion.  

For movement, texture, and four-season appeal in your hot, dry garden, ornamental grass is a great option. Many also have great wildlife appeal, providing nesting material and food for birds. Check out these ornamental grasses that will add beauty and function to your hot, dry garden.
