Lavandula angustifolia (lavender or English lavender, though not native to England; also common lavender, true lavender, narrow-leaved lavender), formerly L. officinalis, is a flowering plant in the family Lamiaceae, native to the western Mediterranean, primarily the Pyrenees and other mountains in northern Spain. It is a strongly aromatic shrub growing as high as 1 to 2 metres (3.3 to 6.6 ft) tall. The leaves are evergreen, 2–6 centimetres (0.79–2.36 in) long, and 4–6 millimetres (0.16–0.24 in) broad. The flowers are pinkish-purple (lavender-coloured), produced on spikes 2–8 cm (0.79–3.15 in) long at the top of slender, leafless stems 10–30 cm (3.9–11.8 in) long.
The flowers and leaves are used as an herbal medicine, either in the form of lavender oil or as an herbal tea. The flowers are also used as a culinary herb, most often as part of the French herb blend called herbes de Provence.
