About
Lavandula dentata, the fringed lavender or French lavender, is a species of flowering plant in the family Lamiaceae, native to the Mediterranean basin, Eritrea, Ethiopia, Yemen, and the Arabian Peninsula. Growing to 60 cm (24 in) tall, it has gray-green, linear or lance-shaped leaves with toothed edges and a lightly woolly texture. The long-lasting, narrow spikes of purple flowers, topped with pale violet bracts, first appear in late spring. The whole plant is strongly aromatic with the typical lavender fragrance.
Its native habitat includes low hills with limestone substrates amidst other shrubs. It is present on Madeira and the Canary Islands.
