Is an aromatic evergreen shrub with leaves similar to hemlock needles. The plant flowers in spring and summer in temperate climates, but the plants can be in constant bloom in warm climates; flowers are white, pink, purple or deep blue. Rosemary also has a tendency to flower outside its normal flowering season; it has been known to flower as late as early December, and as early as mid-February (in the northern hemisphere).
It is native to the Mediterranean and Asia, but is reasonably hardy in cool climates.
