Rosmarinus officinalis ‘Lockwood de Forest’, commonly known as trailing rosemary, is a low-growing, evergreen shrub valued for its prostrate, spreading habit and aromatic foliage. It forms a dense mat of fine, needle-like, dark green leaves with a silvery underside, and produces small, pale blue to lavender flowers in spring and intermittently through warmer months. It is commonly used as a groundcover, for cascading over walls, in rock and gravel gardens, and in coastal or low-maintenance plantings, where its drought tolerance and informal habit are advantageous.
