Rosmarinus officinalis 'Tuscan Blue'

Tuscan Blue Rosemary

Rosmarinus officinalis 'Tuscan Blue' produces clear blue flowers along its upright stems, appearing in late winter to spring with occasional bloom at other times of year. Narrow, needle-like leaves are deep green with a paler underside, releasing a strong, aromatic scent when brushed. The foliage forms a dense, upright framework with a refined texture, while the flowers are spaced along the stems in small clusters that attract bees and other pollinators.
