Chasmanthium latifolium

Northern Sea Oats (Chasmanthium latifolium) is a perennial ornamental grass known for its distinctive, flat, oat-like seed heads that dangle gracefully from arching stems. It typically grows 2 to 4 feet tall and spreads by rhizomes, forming attractive clumps that can naturalize in the landscape. This grass thrives in partial shade but can tolerate full sun if provided with adequate moisture. Northern Sea Oats prefers moist, well-drained soils and is adaptable to a range of conditions, making it suitable for woodland gardens, stream banks, and shaded borders. Its foliage turns a striking bronze in the fall, adding year-round interest to gardens.
