The evergreen shrub originated in the Mediterranean area, but it is today cultivated almost everywhere in the world, primarily for its aromatic leaves. Rosemary has been named the Herb of the Year in 2001 by the International Herb Association. It was one of the herbs introduced to Britain by the Romans and this piney-scented plant is still particularly loved today by the Italians and the British, who use it frequently in their cooking.
In ancient Greece and Rome rosemary was believed to strengthen the memory, which accounts for its being known as the herb of remembrance and fidelity. Rosemary was an essential part of the apothecary's repertoire during the Renaissance. The French regarding it as a cure-all, Hippocrates, Galen, and Dioscorides all prescribed rosemary for liver problems.
The herb of rosemary has several ash colored branches, and the bark is rather scaly and it grows upto a height of three feet. The leaves are with a prominent vein in the middle and margins which are rolled down on the sides. The evergreen leaves of this herb are about 1 inch long, linear, revolute, dark green above and paler and glandular beneath, with an odour pungently aromatic and somewhat camphoraceous.
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 flowers are small and pale blue. Much of the active volatile principle resides in their calyces. The small, blue nettle-shaped flowers appear in May to June and are a great attraction to bees. The whole plant is strongly aromatic. There are several decorative variegated types, but none are as hardy as the ordinary green rosemary.
Rosemary is said to be a native of Mediterranean regions and covers a wide range in Southern Europe and now it is cultivated throughout the world.
Rosemary 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.It will grow in gardens, but prefers to be near the sea.
Rosemary is propagated by seeds, cuttings and layers, and division of roots. Rosemary succeeds best in a light, rather dry soil, and in a sheltered situation, such as the base of a low wall with a south aspect. On a chalk soil it grows smaller, but is more fragrant.
Sow the seeds indoors in a dark room, as this will aid germination, covering a liberal amount of the seeds lightly after sowing. The optimum soil temperature should be around 15c .Although rosemary can take up to 3 months before germination you should start to see some results in about 2-3 weeks. When you have shoot that are around 20cm (4inches) high they may be planted out. Keep the young plant moist but not too wet as the roots easily rot. The new plants should be transplanted in the early autumn to allow them to harden off before the winter, and they may need to be protected with straw where winter conditions are severe. Once established, rosemary bushes do not like to be moved. If this is attempted, the leaves will often turn brown and die, so if it is necessary to transplant try to avoid cutting any roots when doing so and retain as much of the original ball of earth as possible. If happy in its position, rosemary can last for about 30 years. Trim it lightly to maintain its thickness.
Layering is a good technique to be used when one has a rosemary plant already. Stem cuttings can be used for this purpose. One can simply pin down the lower rambling branches of an existing herb to the soil until they root, and this will ultimately form a new plant.
One must take care to space garden plants 0.3 to 0.6 m (1 to 2 feet) apart.
When one is trying to grow rosemary in a container, one must make sure that the plant is slightly pot bound. This means that the container that one must use to grow the plant in must be just big enough for the roots to be housed properly. The pot itself must be kept in a bright and sunny place, because this plant thrives best in open and bright sunshine. The soil must never dry out completely. An established rosemary plant can be kept for three to four years in a container, before it may need to be replaced. The long and straggly branches of the plant must be shortened and trimmed adequately, as this would stimulate new and robust growth of the plant.
The flowers of rosemary are in full bloom in mid to late spring, and sometimes again in late summer.
Pests and Diseases
The rosemary is extremely susceptible to infestations of scale, mealy bugs and spider mites, and to root rot in wet soil, and these are the conditions one must be constantly aware of when one is cultivating the shrub. The leaves must be misted every alternate week.
