About Sea barley
Hordeum maritimum, commonly known as sea barley, is an annual or short-lived perennial grass forming dense tufts. Its cylindrical, hairy spikes, ranging from pale green to yellowish, make it ideal for naturalistic gardens, dune restoration, or as an ornamental potted plant for a rustic, coastal touch.
