Grass Sea Oats

Northern Sea Oats

Sea Oats (Uniola paniculata) is an iconic coastal grass recognized for its tall, slender stems and delicate, oat-like seed heads that sway beautifully in ocean breezes. Native to coastal dunes, it plays a vital ecological role by stabilizing sandy soils with its extensive root system. This makes it an excellent choice for seaside landscapes, dune restoration, and areas prone to erosion. Beyond its functionality, Sea Oats provides striking vertical movement and texture, enhancing the natural beauty of beaches and coastal gardens.

With its ability to tolerate high winds, salt spray, drought, and nutrient-poor soils, it thrives where few other plants can survive. Its golden seed heads emerge in summer and persist into fall, adding seasonal interest while supporting coastal wildlife, including birds and small mammals. Although primarily used in naturalized and conservation settings, Sea Oats can be incorporated into coastal-style residential landscapes when space and conditions allow. Low-maintenance, hardy, and visually elegant, it remains a standout choice for environmentally conscious gardeners and coastal property owners.
