Prostratus

Prostratus is the trailing, creeping form of rosemary widely used as a cascading groundcover and for spilling over walls, containers, and raised beds. Instead of growing upright, its flexible stems sprawl horizontally and drape downward, rooting where they touch soil and quickly covering ground. The fine, needle-like leaves are fully aromatic and culinary, carrying the familiar piney rosemary scent, though the plant is grown as much for its landscape value as for seasoning. Pale blue flowers line the arching branches in spring and again in mild autumns, drawing bees. Prostratus is a favorite in Mediterranean and permaculture plantings for erosion control on slopes and as a living mulch. It is somewhat less cold-hardy than upright types and prefers frost-free or mild-winter climates.
