Common lilac is a large, drought-tolerant shrub. It grows as an upright bush with thick stems and heart-shaped leaves.
In May, it grows very fragrant, purple flowers arranged in a pyramidal cluster. It is a good choice for an informal screen or background plant.
Common lilac has proven to be a tough, drought-tolerant shrub at the Xeriscape Demonstration Garden. Although the flowers are not as showy as some of the newer lilac cultivars, its long-lived, dependable nature makes it a good choice for low-water landscapes.
Remove flower clusters after they have finished blooming. Prune out dead or damaged branches at any time.
