🌱 Planting Installation
Prostrate Rosemary, commonly known as Creeping Rosemary, is a versatile, trailing evergreen subshrub native to the Mediterranean coast. Unlike its upright relatives, this low-growing cultivar stays under one foot in height while spreading six feet or more, forming a dense, cascading carpet of flexible, twisting woody stems. It is densely clothed in small, needle-like, dark green leaves with silvery undersides that release a rich, resinous pine-herbal scent when brushed or crushed.
In late winter and spring, with sporadic repeat blooms through summer and autumn, Creeping Rosemary is smothered in small, delicate lavender-blue flowers that draw honeybees and other beneficial pollinators. Highly valued in landscape design, it serves as an exceptional groundcover for erosion control, dry slopes, rock gardens, and cascading over stone retaining walls or terrace edges.

PLANT CARE & CHARACTERISTICS
Light Requirements: Full Sun (Requires 6+ hours of direct sunlight daily for dense foliage matting and optimal aromatic oil production).
Water Requirements: Low; requires minimal supplemental watering once established.
Drought Resistance: Exceptional (Thrives in hot, dry, Mediterranean-style climates and dry rock garden walls).
Soil Type: Highly adaptable; prefers dry to medium, sandy, gravelly, or limestone soils; pH 6.0–8.0; strictly requires sharp, rapid drainage to prevent root rot. Amending the soil with organic matter such as compost or aged manure before planting can improve soil fertility and drainage, promoting healthy growth.
Deer Resistance: Very High (Pungent resinous oils and aromatic foliage deter deer, rabbits, and livestock).
Pest / Disease Resistance: Exceptional resistance to pests; main threat is powdery mildew or root rot in humid, shaded, or waterlogged conditions.
Pollination: Insect-pollinated; flowers are exceptionally attractive to honeybees, native bees, and butterflies.
Harvest: Continuous, heavy production of aromatic sprigs throughout the year. Harvest fresh trailing sprigs year-round; ideal for culinary use in roasts, marinades, and oil infusions.
Storage / Shelf Life: Fresh sprigs keep 1–2 weeks refrigerated; leaves can be dried or frozen in olive oil for long-term storage (1+ year).
Pruning: Prune light trailing ends after main spring flowering to encourage dense growth and manage spread. Avoid cutting hard back into old, leafless woody stems.
