Lavandula Hybrid. A popular Lavender that produces an abundance of long stemmed, dark lavender flower heads through-out the summer. These are used commercially for dried flowers and oil production. Just lovely in the garden and will help attract bees. Well worth planting for the fragrance alone.
'Grosso' is probably one of the most deliciously fragrant of all the Lavenders available to gardeners' today. Evergreen.
