Ornamental Grasses

Using grasses in design and landscapes has become a popular choice over the past few years. They can create a nice modern feel to any yard or patio. Great planted in the ground (a must to over-winter perennial grasses) or in containers.

In general, perennial grasses need a lot of sun. The best grass option for a shady area is ribbon grass. Grasses need a lot of water- especially in their first year until established, and planting them in dry areas should be avoided.
