Extend your lavender season with late blooming Woolly Lavender. Truly silver, Woolly Lavender is a bit more tender than the L. angustifolias or the L. x intermedias. Make sure it has good drainage and it will make a beautiful addition to the garden  with its smoky dark purple blossoms. It looks great planted with dark green foliage plants like Rosemary or Lemon Verbena.
