Lavandula angustifolia Mill. is an important producer of essential oil, which presents the difficulty of propagation stem cuttings. In this work the propagation of plant was carried out by micropropagation technique, in which certain conditions were evaluated in vitro. The micropropagated plants were grown in São Joaquim (SC). The essential oil of the inflorescences was extracted by hydrodistillation and analyzed for their composition by GC/MS in two years of harvest. The culture medium LS showed a better response in the development of shoots. Culture media more diluted as the 1/2 MS and WPM showed high rates of hyperhrydricity and apical necrosis. The BAP influenced the shoot multiplication and the quality being maintained with 1.0 mM over four subcultures. The survival in the acclimatization of plants was 80%. The content of essential oil were 4.0% and 5,25% in the first and second harvest, respectively. The major compounds were linalool (46.88% and 37.25%) and linalyl acetate (10.09% and 12.24%).
