Rosmarinus species
Family: Lamiaceae

Rosemary has long been steeped in myth and symbolism, being reminiscent of friendship in particular. The two species originate from the Mediterranean, where rosemary has traditionally been widely used in cooking. It adds a delicious flavor to lamb, pork, fish and vegetable dishes. Rosemary oil is used in soaps, perfumes and shampoos.

Species

R. oficinalis, common rosemary, is a shrubby, evergreen perennial, to 2 m (6 ft), with upright, branching stems. The needle-like leaves are dark green on top, silvery on the undersides, and very fragrant. The pale blue flowers are borne in terminal clusters. It is popular for borders, rockeries and container growing. Var. albifloras has white flowers; 'Benenden Blue' has blueish violet flowers; 'Tuscan Blue' has blue-violet flowers.

R. officinalis Prostratus Group is a dwarf rosemary to 20 cm (8 in) high, with a spreading prostrate habit and blue flowers. It is less hardy than the species. This is ideal for covering sunny banks or for a rock garden.

Cultivation

Rosemary needs an open, well-drained soil and a sunny situation. It does well in rocky, dry coastal areas, but needs shelter in cold regions. Prune after flowering to retain shape and encourage new growth. Propagate from seed sown in spring or from semi-ripe cuttings in summer, both in a garden frame.

Climate

Best in areas of low humidity, with hot, dry summers and cool to cold winters. Zone 7 or 8.
