Sea Oats (Uniola paniculata)

Sea oats (Uniola paniculata) are tall, grass-like plants native to coastal dunes and beaches. They play a vital ecological role by stabilizing sand, preventing erosion, and supporting dune formation. Their sturdy, deeply-rooted stems and broad, feathery seed heads help trap wind-blown sand, which in turn builds and maintains healthy dune systems. Beyond their environmental importance, sea oats are valued for their aesthetic appeal and are often protected by law because they help preserve the dynamic landscape of coastal areas. They thrive in salty, sandy soils and are a key indicator of healthy beach ecosystems.
