Northern Sea Oats (Chasmanthium latifolium) is native to the Eastern US. In nature, it grows in the woods, along streams or on rocky slopes, helping to stabilize the soil. Sea Oats forms tufts of bamboo-like foliage that will be topped off with oats-like, gracefully drooping seed heads in the fall. Add them to your flower arrangements, either fresh or dried. After the first frosts, the leaves turn an attractive coppery color before they pale for the winter. Leave your plants as they are for the winter, they will add a touch of interest to the landscape.
