Noteworthy CharacteristicsReddish blooms which appear later than common lilacs

CareGrow in reasonably fertile, well-drained soil in full sun; prefers neutral to slightly alkaline soil. Promptly deadhead spent blossoms to produce more robust blooms for the following year. Prune lightly in late winter or early spring to maintain a healthy framework, remembering that most species form flowers the previous season. Plant in areas with good air circulation to thwart disease. Because lilacs are fire retardant, they can be considered for planting near homes that are susceptible to wildfires. Most lilacs require a period of chilling dormancy.

PropagationTake softwood cuttings or layer in early summer; graft in winter; bud in summer.

ProblemsPowdery mildew, dieback, leafroll virus, mycoplasma-like organisms (MLO), root knot nematode, Verticillium wilt, witches' broom, bacterial leaf spot, anthracnose, borers, scale, caterpillars.
