Lavender belongs to the family Labiatae (Lamiaceae) and subfamily Nepetoideae (synonyms Lavandula angustifolia, Lavandula vera, Lavandula latifola, Lavandula officinalis, Lavandula spica, and Lavandula delphinensis). Lavender is a shrubby plant with aromatic flowers and narrow leaves. The plant grows from 1 to 3 feet in height. The arrangement of leaves is opposite, sessile, with bluntly quadrangular branches, finely pubescent, possessing stellate hairs (Upson, 2002). The flowers consisting of cymes are present in the form of inflorescence at the end of branches either with opposite decussate or an alternate spiral arrangement. The cymes are found in different sizes, shapes, and nervation characteristics of different species. The plant flowers possess either a single flower or three to nine flowers per cyme, without or with bracteoles, respectively. The calyx and corolla vary in shape, size, and color (Upson, 2002).
