Lilacs delight the senses with their colorful flower panicles and sweet fragrance that wafts on the spring breeze. This easy-to-grow shrub is a delightful addition to the landscape or in the garden. They're equally prized as a cut flower and will perfume the home with their sweet lilac fragrance. Most lilacs grow best when planted in full sun or an area that receives several hours of direct sunlight each day. If you have less space, consider a smaller growing variety. Lilacs come in a range of hues, from pretty pink to purple.
