Used in Antiquity and very much in evidence in the Middle Ages, this plant has a bushy growth habit, growing to between 40 and 60 cm tall. Its oval, grey-green leaves are highly fragrant. This hardy plant can withstand temperatures as low as -15°C, and is equally at home in the kitchen garden or the ornamental garden. In summer, it blooms in spikes, often purplish-blue in colour, which can vary according to variety. Like thyme, sage belongs to the Lamiaceae family.
