Paul Thirion is a classic French hybrid lilac known for its large, fully double blooms and striking color. In mid-spring, this variety produces dense, upright panicles packed with soft rose-lilac flowers that open from deep pink buds. The layered florets give the blooms a plush, full appearance, and the fragrance is strong and sweet—perfect for cutting and bringing indoors.
This upright, deciduous shrub grows 9 to 12 feet tall and 8-10 feet wide, developing a well-branched, rounded habit. It thrives in full sun and well-drained soil and, like other Syringa vulgaris cultivars, benefits from pruning immediately after flowering to promote next season’s bloom. Hardy and long-lived, Paul Thirion makes a standout specimen or flowering hedge in traditional and cottage-style gardens.
