Species of plant.Salvia rosmarinus, commonly known as rosemary, is a shrub with fragrant, evergreen, needle-like leaves and white, pink, purple, or blue flowers, native to the Mediterranean region.Special cultivars like 'Arp' can withstand winter temperatures down to about −20 °C.The plant flowers in spring and summer in temperate climates, but the plants can be in constant bloom in warm climates; flowers are white, pink, purple or deep blue. Rosemary also has a tendency to flower outside its normal flowering season; it has been known to flower as late as early December, and as early as mid-February (in the northern hemisphere).Salvia rosmarinus is now considered one of many hundreds of species in the genus Salvia. Formerly it was placed in a much smaller genus, Rosmarinus, which contained only two to four species including R. officinalis, which is now considered a synonym of S.
rosmarinus.History [ edit ].Rosemary came to England at an unknown date; the Romans probably brought it when they invaded in the first century, but there are no viable records about rosemary arriving in Britain until the 8th century CE.After this, rosemary is found in most English herbal texts, and is widely used for medicinal and culinary purposes. Rosemary is used as a decorative plant in gardens.The leaves are used to flavor various foods, such as stuffing and roast meats. It is considered easy to grow and pest-resistant.The groundcover cultivars spread widely, with a dense and durable texture.Cultivars [ edit ].'Albus' – white flowers.'Benenden Blue' – leaves narrow, dark green.'Haifa' – low and small, white flowers.'Pyramidalis' (or 'Erectus') – fastigate form, pale blue flowers.'Salem' – pale blue flowers, cold-hardy similar to 'Arp'.Dried leaves.Phytochemicals [ edit ]. Rosemary essential oil contains 10–20% camphor.Folklore and customs [ edit ].Rosemary was considered sacred to ancient Egyptians, Romans, and Greeks.In Australia, sprigs of rosemary are worn on ANZAC Day and sometimes Remembrance Day to signify remembrance; the herb grows wild on the Gallipoli Peninsula, where many Australians died during World War I. .
