Sea Oats Uniola paniculata

Other Common Name(s):

Phonetic Spelling
yoo-nee-OH-luh pan-ick-yoo-LAY-tuh
Description

Sea oats are a native warm-season grass that is slow-growing and long-lived. They are important in preventing damage to dunes during storms as they have both deep taproots and lateral rhizomes to help hold the soil in place. Being cover with sand repeatedly actually stimulates growth. They are damaged by pollution such as runoff from marinas and encroaching urbanization, foot traffic and off-road vehicles. Sea oats are a protected grass in several states along the southeastern Atlantic coast including NC.

The plant will grow to 6 feet tall with narrow green leaves up to 2 feet long and less than an inch wide. The panicles are made up of many flat spikelets that are green turning to light brown at maturity containing seeds. The panicles with their attractive drooping seed heads can be used in dried arrangements. 

Plant in full sun in sandy soils. It tolerates dune conditions with blowing sand, drought and brief inundations of saltwater.
