Include beautiful English lavender (Lavender angustifolia) in your garden plans for a plant that’s packed with fragrance. Leaves, flowers and stems all exude that classic lavender scent, and when sun warms the plants, you only need to brush the leaves to release the fragrance. Lavender helps keep biting mosquitoes at bay outdoors. In the evening, reap its bug-busting benefits by crushing flower buds and leaves and rubbing them on your skin. Tuck lavender into pots or planting beds. Plants grow 12 to 18 inches tall and wide. Hardy in Zones 5-9.
