The lavenders (Lavandula) are a genus of 39 species of flowering plants in the mint family, Lamiaceae, native to the Mediterranean region south to tropical Africa and to the southeast regions of India. The genus includes annuals, herbaceous plants, subshrubs, and small shrubs. The native range extends across the Canary Islands, North and East Africa, Southern Europe and the Mediterranean, Arabia and India. Because the cultivated forms are planted in gardens worldwide, they are occasionally found growing wild as garden escapees, well beyond their natural range. However, since lavender cross-pollinates easily, there are countless variations within the species. The color of the flowers of some forms has come to be called lavender. The leaves are long and narrow in most species. In other species they are pinnately toothed, or pinnate, sometimes multiple pinnate and dissected. Flowers are borne in whorls, held on spikes rising above the foliage. Flowers may be blue, violet or lilac. The calyx is tubular, with five lobes. The corolla is often asymmetric. The most common "true" species in cultivation is the common lavender Lavandula angustifolia (formerly L. officinalis). A wide range of cultivars can be found. Other commonly grown ornamental species are L. stoechas, L. dentata, and L. multifida.

Lavenders are widely grown in gardens. Flower spikes a...More: http: //booksllc.net/?id=1764
