Salvia rosmarinus (formerly Rosmarinus officinalis) is a bushy evergreen shrub, and one of the world's best-loved herbs. Commonly called Rosemary, it is known as the plant of remembrance and friendship. It is covered in dense, aromatic foliage comprising dark green leaves which reduce to thin, needle-like protrusions. These curve at the edges and have paler-coloured, felted texture on the undersides. Flowers are small and delicate, typically appearing throughout the year from spring onwards. Flower colour ranges from dark to light shades of purple, blue, pink and white. Many cultivars have been developed for garden use. Growth habit varies from upright to ground-hugging and can be used in sunny borders, rock gardens and for low-growing hedging. Rosemary is used for flavouring food and as an antiseptic herb. It is drought-resistant and attractive to bees and butterflies.
