Korean lilac is a dense, rounded-oval, non-suckering, deciduous shrub which typically grows 4-8’ tall with a spread of 6-10’. ‘Palibin’ is a compact, low-spreading cultivar which typically grows 4-5’ tall with a spread of 5-7’. Pale pink, sweetly-fragrant single flowers arranged in dense, terminal clusters (panicles to 4” long) cover this shrub with a profuse bloom in late April to early May (St. Louis area). Elliptic-ovate, dark green leaves (to 1.5” long) are smaller than the species. No fall color. This shrub is sometime grafted to a 4’ standard and sold as a small tree with a dense, rounded crown. Tree form typically matures to 8’ tall.
No serious insect or disease problems. This Korean lilac is extremely resistant to powdery mildew. Flower buds are susceptible to frost injury in early spring.
Effective as a specimen or massed. Shrub borders, foundations. Good screen or informal hedge for property lines. Korean lilacs are generally more attractive than many other species of lilacs in summer due to their mildew-free foliage.
