French or Spanish Lavender (also once known as Stickadove Lavender) is native to the Mediterranean coastline of Europe. British herbalist John Gerard noted in 1633 that the apothecaries used it as a cure for headaches and chest colds and he recommended that the plants be protected during winter or put into pots or tubs and brought indoors. In fact, north of Zone 8, this lavender species should be maintained in an unheated room or porch during the winter months. Jefferson cultivated the hardier English Lavender (Lavandula angustifolia).
