Fragrance is pungent and piny. Both flowers and leaves can be used in cooking and for garnishes. Dried or frozen rosemary is stronger than fresh. Rosemary thrives in full sun in well- drained soil with a pH of 6.0 to 7.5. Warm, dry summer climates are ideal.
Good drainage is essential, as roots easily develop root rot.
Cuttings and layerings from established plants make the best propagation material. Rosemary can be started from seed, but germination rates are very low and it takes up to three years to produce a bush sizable enough for harvesting. Harvesting can be done throughout the year, but care should be taken to not remove more than 20 percent of the growth at a time. To dry leaves, cut individual branches and strip the leaves from the branches onto screens or paper. Place in a shady area with good air circulation, or dry whole or partial branches for decorative use.
