Answer: Lavendula dentata is the botanical name for your French Lavender. The plant will grow to 3' feet tall with gray-green leaves and produce lavender purple flowers almost continually in your zone. If you cut the plant back after flowering, it will produce flowers again in about two weeks. French Lavender is tolerant of wet, humid summers and like a bright sunny spot in the garden. It will adapt well to growing in containers, just be sure to supply ample moisture during the growing season (February - November). The flowers are used to repel clothes moths and also used in cooking.
