Lilacs are treasured for their colorful flower panicles and sweet fragrance that perfumes the warm spring air. This easy-to-grow classic shrub is a delightful addition to the landscape or in the garden. Lilacs are equally prized as a cut flower and will scent 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. Lilacs come in a range of hues, from pretty pink to purple. Don't have much space in your garden or landscape? Consider a smaller growing variety.
