This herb is an evergreen shrub, with lovely aromatic linear leaves. Colored a dark shade of green above and white below, the leaves of the rosemary give off a beautiful fragrance, and with its small pale blue flowers, the plant is cultivated extensively.
Rosemary grows freely in much of southern Europe and is cultivated throughout the world, although the shrub is native to the Mediterranean regions. This perennial plant needs full sun, and a sandy, well-limed soil, but it can also be wintered indoors. Rosemary generally grows best in light, well-drained, rather dry soil, with its recommended pH range about 6.0 to 7.5. If the soil's pH is below 6.0, one can safely add lime or ground-up eggshells to the soil.
