Lavandula angustifolia (also Lavandula spica or Lavandula vera; common lavender, true lavender, or English lavender (though not native to England); formerly L. officinalis) is a flowering plant in the family Lamiaceae, native to the western Mediterranean region, primarily in the Pyrenees and other mountains in northern Spain. It is a strongly aromatic shrub growing to 1–2 m tall. The leaves are evergreen, 2–6 cm long and 4–6 mm broad. The flowers are pinkish-purple (lavender-coloured), produced on spikes 2–8 cm long at the top of slender, leafless stems 10–30 cm long.
The species name angustifolia is Latin for narrow leaf. In addition to its use as an ornamental plant, the flowers and leaves are also 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.
