Lavender fills the early-summer garden with sensory delights: beautiful purple-tone blooms atop foliage that oozes fragrance on a sunny afternoon. Once established, Lavender plants require little care or maintenance. While they should be watered regularly early on, established plants need little water, as they are extremely drought tolerant. Every part of the plant is infused with aromatic oil, making this a choice herb to place along pathways or near outdoor seating areas so you can savor the fragrance. Lavender varieties abound: the darker the flower, the more intense the aroma - and the flavor in cooking.
