Lavandula

A small evergreen shrub with very fragrant, white-wooly, conifer-like leaves. Bears clusters of small, deep blue flowers in summer. Interestingly, the fragrance of lavender has now been demonstrated to promote sleep (only recently proven scientifically, although lavender has a long history of use as an ingredient in pillows to promote sleep). May freeze back in winter when cold is severe but will then behave as a perennial. Best in a sunny, well-drained location.
