This highly aromatic perennial boasts numerous variations in flower color, time of bloom, fragrance and plant height. Give lavender a sunny site and well-drained, neutral soil. Once the plant is established, lavender is drought-tolerant; most types languish in heat and humidity. Giving lavender a haircut after flowering will promote branching and encourage additional blooms.
This strong-scented lavender is a popular garden choice and a favorite in culinary and craft projects. Expect flowering late spring to early summer with a second re-bloom possible, especially if deadheaded. Sweet-smelling leaves provides year-long value. Cultivars include white, pink, and shades of purple and blue. English lavender averages 2 to 3 feet tall at maturity. USDA Hardiness Zones: 5 to 8
English lavender 'Munstead'
This compact version of English lavender averages 18 inches tall (two feet tall when flowering) and has violet-blue flowers. Munstead is more heat tolerant and starts blooming a little later than many other English lavenders. Its sweet fragrance and color make it ideal for cooking. USDA Hardiness Zones: 5 to 9
English lavender 'Blue Ice'
A relatively new cultivar, this English lavender features pale blue flowers in midsummer on a 24-inch-tall plant. Ideal for cottage gardens featuring other pastels, 'Blue Ice' is especially attractive to butterflies. Its lovely fragrance makes it an excellent choice for potpourri. USDA Hardiness Zones: 6 to 9
