Creeping Rosemary 'Prostratus' (Rosmarinus officinalis 'Prostratus') gives you a fragrant, trailing evergreen groundcover that softens edges and spills neatly over walls. You will enjoy fine, needle-like foliage year-round and soft blue flowers that add seasonal color without overwhelming nearby plants. Use it where you want a tidy, low profile plant with a Mediterranean look and a classic rosemary scent.
Give it a sunny to lightly shaded spot and soil that drains quickly. In heavy or consistently wet soils, roots can decline, so improving drainage or planting on a slight berm helps. Once established, it handles dry periods well, making it a strong choice for low-water beds, hot exposures, and coastal areas when drainage is good.
At maturity it typically stays about 6-12 inches tall, while spreading to form a wide mat. You can lightly shear after flowering or as needed to keep the edges crisp and encourage fresh growth. It also does well in containers and hanging planters where the branches can trail naturally.
Because it is culinary rosemary, you can harvest small sprigs for cooking when you want a fresh, piney flavor. Clip lightly and regularly rather than cutting back into old, leafless wood, and your plant will stay attractive and productive through the seasons.
