lavandula

Lavandula is a genus of flowering plants in the mint family, Lamiaceae, native to the Mediterranean region. Commonly known as lavender, these plants are evergreen shrubs or subshrubs valued for their fragrance and ornamental appeal. The group includes true lavenders such as Lavandula angustifolia, as well as hybrids like Lavandula x intermedia, and other species including L. stoechas (Spanish lavender) and L. dentata (fringed lavender).

Most lavenders have woody stems, narrow gray-green leaves, and produce spikes of densely packed tubular flowers in shades of purple, blue, or white. The flowers attract bees and other pollinators. The essential oil, rich in linalool and linalyl acetate, provides the characteristic scent and is used in perfumery, cosmetics, and aromatherapy.

Lavandula species are native to sunlit, dry regions of southern Europe, northern Africa, and western Asia. They prefer full sun, well-drained soil, and good air circulation. They are generally drought-tolerant once established, with cold tolerance varying among species and cultivars.

Cultivation and care emphasize drainage and sun exposure. Plant in a site with full sun and light, sandy or gritty soil. Avoid overwatering and heavy soils. Prune after flowering to maintain shape and vigor. Propagation is commonly by semi-hardwood cuttings or layering. Some cultivars are more winter-hardy than others and may require protection in colder climates.

Uses and chemistry: Lavenders are widely grown ornamentally and in borders, beds, and rock gardens. The essential oil is valued in perfumes, cosmetics, and traditional medicines, while lavender flowers are sometimes used as a culinary garnish or flavoring in small amounts.

Etymology and history: The name Lavandula derives from Latin lavandula, a diminutive of lavare, to wash, reflecting historic use in baths and laundry for fragrance. Lavender has long-standing ceremonial and medicinal associations across cultures.
