Tough and versatile, rosemary grows most luxuriantly just above the tide line, braving wind and salt spray—but it will thrive inland, even enduring blistering sun and poor alkaline soil, if given moderate water and infrequent light feeding.
Height ranges from as low as 1 ft. to as tall as 6 ft. or more. Plants are thickly clothed in narrow, typically 1 to 1 1/2-in.-long resinous, aromatic leaves that are usually glossy dark green above, grayish white beneath.
Small clusters of 1/4- to 1/2-in. blossoms in various shades of blue (rarely pink or white) bloom through winter and spring; bloom occasionally repeats in fall. Blossoms attract birds, butterflies, bees; produce excellent honey. Leaves are widely used as a seasoning.
