|Common lavender (Lavandula angustifolia)|
Lavandula angustifolia (lavender most commonly true lavender or English lavender, though not native to England; also garden lavender, common lavender, narrow-leaved lavender), formerly L. officinalis, is a flowering plant in the family Lamiaceae, native to the Mediterranean (Spain, France, Italy, Croatia etc.).
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.
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 and may benefit from increased drainage provided by inorganic mulches such as gravel. It does best in Mediterranean climates similar to its native habitat, characterised by wet winters and dry summers. It is fairly tolerant of low temperatures and is generally considered hardy to USDA zone 5. It tolerates acid soils but favours neutral to alkaline soils, and in some conditions it may be short-lived.

The flowers and leaves are used as a herbal medicine, either in the form of lavender oil or as a herbal tea. The flowers are also used as a culinary herb, most often as part of the North American version 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 (spike lavender) are called Lavandula x intermedia. They bloom later than the ordinary English lavenders.
