Rosemary (Rosmarinus officinalis) is an aromatic evergreen shrub with thin, piney-scented, gray-gray leaves. Native to the Mediterranean, it needs a spot with full sun, and must have excellent drainage and good air circulation to grow well. Water only enough to keep the plant from drying out. Feed lightly once a year in spring. In mild-winter areas, where ground doesn't freeze, Rosemary can be planted right in the ground. In cold winter areas with ground-freezing frosts, Rosemary should be grown in a pot or other container outside over the warm summer season and then brought inside during the cold weather. Do not repot often as this causes shock. Cut back your Rosemary about 1/3 before bringing it indoors to overwinter in a spot that gets at least 6 hours of direct sun. After several years, carefully repot your Rosemary into a slightly larger container. Given the above good growing conditions, Rosemary rarely has problems with insects or disease. Hardy in Zones 7-10.
