Tuscan Blue Rosemary (Salvia rosmarinus ‘Tuscan Blue’) is an upright, vigorous rosemary selection producing bold, intensely aromatic, broad leaves and vivid blue-purple flowers. One of the finest and most flavorful rosemary varieties for culinary use, it also grows into a striking, formal shrub reaching 4-6 feet tall and wide – excellent as a hedge, specimen plant, or backdrop in the herb garden.
At Flying Rabbit Farm, our Tuscan Blue Rosemary transplants are grown for strong root development and excellent heat and drought performance suited to Central Texas.
