Rosemary is a generally erect, rounded, evergreen shrub with intensely fragrant foliage. The leaves are commonly used for culinary flavoring, toiletries and sachets. Rosemary is native to the Mediterranean, Spain and Portugal. Where winter hardy, it will grow as a shrub to 4-6 tall. Tiny, two-lipped, pale blue to white flowers bloom in axillary clusters along the shoots of the prior years growth. Flowers are attractive to bees.

Winter hardy to USDA Zone 8-10 where it may easily be grown in light, dry to medium, well-drained soils in full sun. Tolerates light shade, but best performance is in full sun. Established plants have good drought tolerance. Performs poorly in heavy clay soils. Wet, poorly-drained soils in winter are usually fatal. If desired, prune plants after bloom to encourage dense foliage growth. Plants may also be pruned to specific shapes. Best propagated by cuttings. In the St. Louis area, plants may be grown in containers (clay pots best) that should be overwintered indoors in a sunny, humid but cool room. Plants do not perform well in dry winter heat. Take pots outside in mid spring around the time of last frost.
