Dunes and Uniola paniculata, also known as sea oats, seaside oats, araña, and arroz de costa,[1] is a tall subtropical grass that is an important component of coastal sand dune and beach plant communities in the southeastern United States, eastern Mexico and some Caribbean islands. U. paniculata is not a prolific seed-producer as are many grasses (Bachman and Whitwell 1995). [2], Sea oats are well suited to saline environments, and as such, are important to barrier island ecology and are often used in sand stabilization projects because their long root structure firmly holds loose sand. The plant produces a well- developed rhizome (horizontal root) system, and 0.5-1.5 m (1.6-5 ft) tall culms (stems) sprout from the node along the rhizomes. Nursery production Growth in this species can be rapid under optimal central Florida. It is uncommon in swales between dunes where salt spray is limited, and it is rarely found inland.[1][2]. Orlando, FL. Stoma close when soil moisture reaches 8.5%.     (southern sea oats).
