Common lilac is a suckering, upright medium-tall shrub that is best located in the outside row of windbreaks. Fragrant white to lavender flowers bloom during May. Lilac is rarely used in wildlife plantings since it does not form thickets and the seeds have little food value.
Powdery mildew and oystershell scale are common problems.
