Rosemary is a perennial evergreen herb that is irregularly mounded and is valued for its fragrant, ornamental foliage and as an enhancement in cooking. It blooms from fall to spring. Key ID elements are the aromatic linear leaves which are green on top and whitish underneath, and also the axillary flowers. Flower color fades in hot weather to blend with foliage and is most pronounced in late winter. It is used in containers, as low hedges, and in places where it can cascade. Rosemary has a low tolerance for wet, humid environments and requires careful tending in an appropriate spot in North Carolina gardens. The plant has an arching or rounded form and, when mature, can reach 6 feet in height. Some cultivars are grown to be small enough to keep indoors. Note that the cultivar, 'Prostratus', has a form that is lower and creeping.
