Frank Klager is a distinguished French lilac known for its richly colored, double blooms and strong, classic fragrance. In mid- to late spring, it produces large, upright panicles of deep violet-purple flowers with layered petals that create a full, lush appearance. The saturated color and heavy bloom set make it a striking addition to the spring landscape.
This upright, deciduous shrub typically grows 9 to 12 feet tall and 8 to 10 feet wide, forming a dense, rounded habit over time. It performs best in full sun and well-drained soil and benefits from pruning immediately after flowering to promote vigorous growth and consistent blooming. Like most common lilacs, it is extremely cold-hardy and long-lived, thriving for decades once established.
