Features: This upright ornamental grass has bright green foliage in the summer that turns a coppery bronze in the fall and winter. If foliage is left, this species provides good winter interest with its good texture. Sea oats also produces attractive drooping, flat seed heads that can be used in dried flower arrangements.12
Siting: This species is great as a border or in naturalized areas as well as along streams and water gardens. Can also be used as an accent plant.12
Care: Plant crown at soil level18. At planting, water the roots and surrounding area slowly and deeply. Keep soil moist until plant is established, then apply enough water to thoroughly moisten the root zone when the soil is dry or during drought. Modify water recommendations to reflect site drainage and rainfall. Apply 3” of mulch over the planted area. Do not allow mulch to touch the plant stems18. This low maintenance species does well in full sun to part shade and tolerates poor soils, but may need staking or other support. If foliage is left in place over winter, cut back in early spring12.
Pests: No serious pest or disease problems12. Plants are relatively pest resistant if cultural preferences are met.
