Rosmarinus officinalis ‘Tuscan Blue’
Tuscan Blue Rosemary is a vigorous, upright rosemary variety prized for its aromatic evergreen foliage, striking blue flowers, and strong vertical growth. This classic Mediterranean herb forms a tall, shrubby plant that can reach up to 6 feet tall, making it perfect for hedges, screening, and dramatic herb garden plantings.
In spring through summer, Tuscan Blue produces clusters of clear blue flowers that attract bees and other pollinators. The needle-like leaves release a rich rosemary fragrance and are widely used in cooking to season roasted meats, vegetables, breads, and Mediterranean dishes.
This hardy herb thrives in full sun and well-drained soil, especially sandy or rocky conditions. Once established, Tuscan Blue Rosemary is drought tolerant and very low maintenance, making it ideal for water-wise landscapes, herb gardens, containers, and Mediterranean-style plantings.
