What is Rosmarinus prostrata?

Rosmarinus prostrata is a creeping form of rosemary with narrow, grey-green leaves and dainty, sky-blue blossoms that appear from spring through autumn. Its trailing stems make it perfect for spilling over retaining walls, rockeries, or banks, where it forms a fragrant, dense mat. Prostrate Rosemary is an attractive alternative to more upright classics like Rosmarinus officinalis and brings a more informal, natural look to gardens. If you're keen to explore other varieties, Rosmarinus 'Blue Lagoon' and Rosmarinus 'Tuscan Blue' offer unique colours and growth forms.

Uses for Rosmarinus prostrata in the Garden

One of the most popular uses for Rosmarinus prostrata is as a groundcover. It is ideal for suppressing weeds on banks, slopes, or cottage garden edges and can even be used between pavers. This hardy rosemary variety also performs beautifully in coastal gardens thanks to its tolerance for salt-laden winds. For culinary enthusiasts, Prostrate Rosemary can be clipped for sprigs of fresh flavour in roasts and soups, just like its upright counterparts.

Blending Rosmarinus prostrata with other creeping and groundcover plants can create year-round interest. Try pairing with Casuarina Cousin It, Juniperus procumbens Nana (Japanese Dwarf Juniper), or Cotula squalida Platt's Black for varying foliage and texture. If you're seeking additional hardy trailing rosemary options, consider Rosmarinus 'Lockwood de Forest' (Creeping Rosemary).

Growing Tips

Rosmarinus prostrata is low maintenance and drought tolerant once established. Plant in full sun and free-draining soil for best results. Occasional trimming will keep plants tidy and encourage denser growth. It's also beneficial to plant Rosmarinus prostrata where you can appreciate its fragrance up close—near seating areas, paths, or driveways.

This plant tolerates light frosts and coastal conditions well, making it an excellent choice for challenging garden spots. For especially exposed or dry garden areas, consider pairing with tough groundcovers like Isotoma fluviatilis and Grevillea New Blood (Grevillea juniperina New Blood).
