Discover how to grow and care for trailing rosemary, a versatile and fragrant herb. Learn expert tips on planting, maintenance and uses in cooking and landscaping. Perfect for gardens, containers and hanging baskets.
Trailing rosemary (Rosmarinus officinalis var. prostratus) is a low-growing, spreading variety of the popular herb. It thrives in full sun, well-draining soil, and moderate watering. This drought-tolerant plant is ideal for rock gardens, hanging baskets, and as a ground cover. It offers the same aromatic leaves as upright rosemary, perfect for culinary and ornamental uses.
