|Common Lavender (Lavandula angustifolia)|
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 (0.79–2.4 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 (0.79–3.1 in) long at the top of slender, leafless stems 10–30 cm (3.9–12 in) long.
English lavender is commonly grown as an ornamental plant. It is popular for its colourful flowers, its fragrance and its ability to survive with low water consumption. It does not grow well in continuously damp soil. It is fairly tolerant of low temperatures, generally considered hardy to USDA zone 5. It tolerates acid soils but favours neutral to alkaline soils. In some conditions it can be short-lived.

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.
Lavender essential oil, when diluted with a carrier oil, is commonly used as a relaxant with massage therapy. Products for home use, such as lotions, eye pillows (including lavender flowers or the essential oil itself) and bath oils, etc., are also used. Both the petals and the oil are the most popular ingredients in handmade soap.
Lavandula hybrids are referred to as lavandins. Hybrids between L. angustifolia and L. latifolia are called Lavandula x intermedia. They bloom later than the ordinary English lavendars.
