toothed lavender, French lavender, fringed lavender
Strongly aromatic evergreen shrub, woody at the base, with upright branches, grey-green leaves and lilac flowers for most of the year. Native to the Mediterranean region, the Cape Verde Islands and Madeira. Leaves are sticky, linear, 3-4 cm long, 0.5 cm wide. Easy to distinguish from other lavender species by the bluntly toothed leaf margins. Flowers are arranged in tight spikes, topped with pale purple bracts, to about 5 cm long on stems held above the foliage. Attracts bees and butterflies. Lavandula dentata does not have the typical lavender fragrance. Its smell is more aromatic than "flowery", rather like a blend of rosemary and lavender scents.
Prefers a hot and sunny position in well-drained neutral to alkaline soil, not too fertile, but adapts well to a range of situations. It is tougher and less fussy in terms of growing conditions than most other lavender species. Susceptible to root rot in poorly drained soils. Very drought-tolerant once established. Tolerates light to medium frosts (to about -7oC). Prune after flowering to keep compact and remove spent flowers.
Mainly grown for its silvery grey foliage and subtle flowers. Suitable for topiary and hedging purposes. May also be grown in containers. Excellent choice for coastal gardens and for hot and dry areas.
