Rosmarinus officinalis 'Tuscan Blue', commonly known as Tall Rosemary, is an upright, evergreen shrub known for its rich fragrance and deep blue blooms. This fast-growing rosemary features needle-like leaves—dark green above and silvery beneath—and is more vigorous and taller than typical varieties.
It grows 4 to 6 feet tall (sometimes more in ideal climates) and produces showy, pollinator-attracting flowers from late winter through spring. The plant is heat- and drought-tolerant, thrives in full sun, and is prized both ornamentally and in the kitchen for its savory, pine-like flavor.
