Salvia rosmarinus, formerly known as Rosmarinus officinalis, is native to the Mediterranean region. The variety 'Prostratus' is a selected form valued in gardening for its creeping growth habit.
Salvia rosmarinus is an evergreen shrub with low growth, reaching a maximum height of 30 cm but expanding in width up to 1-1.5 meters. It has long, trailing branches that form a dense carpet of foliage. The leaves are narrow, linear, dark green on the upper surface, and gray-green underneath; they are aromatic and resemble small needles.
Flowering primarily occurs in spring but may continue sporadically throughout the year in mild climates. The flowers are small, blue-lavender or light blue, grouped in clusters along the branches. They attract bees and other pollinators. The fruits are small achenes containing the seeds.
Salvia rosmarinus 'Prostratus' prefers well-drained, sandy, or rocky soils with full sun exposure. It thrives in hot, dry climates typical of Mediterranean regions but can tolerate cold temperatures down to about -10°C. It is drought-resistant and can withstand coastal conditions, including exposure to sea salt.
Salvia rosmarinus 'Prostratus' is highly valued in gardening for its ability to cover the ground, prevent erosion, and create decorative borders. It is often used in rock gardens, flower beds, and as a slope plant. Besides its ornamental value, it is an aromatic plant used in cooking to flavor meats, fish, and vegetable dishes. The leaves contain essential oils with antimicrobial, antioxidant, and anti-inflammatory properties. Its extracts are also used in cosmetics and phytotherapy. This variety is ideal for Mediterranean gardens, xeriscaping, and for those seeking a low-maintenance, resilient plant.
