Lavandula dentata
Fringed lavender is recognized by its toothed leaves and soft mounded habit. It flowers for a long season in warm climates and is favored for containers and coastal sites. Cold tolerance is low so it is best grown where winters are mild or as a seasonal plant. It prefers full sun, excellent drainage, and neutral to alkaline soils. The foliage is aromatic and the flowers carry small bracts.
