Prostrate rosemary (Rosmarinus officinalis 'Prostratus')
This rosemary grows in very fragrant blue-green mounds that will get up to 3' tall. Blue-white flowers appear through mid-summer. Good for cascading over walls and covering slopes; works well in large containers as well. Looks great with salvias, grasses, and roses; likes good drainage and takes little water. Also good for cooking or grilling.
