Lilac Bloomerang is a revolutionary series of hybrid, reblooming deciduous shrubs engineered by Proven Winners. Unlike traditional lilacs that only bloom once for a few weeks in spring, Bloomerang lilacs flower heavily in mid-to-late spring, take a brief summer pause, and then bloom again from mid-summer until the first hard frost. They are highly prized for their compact growth habit, intense fragrance, and exceptional resistance to powdery mildew.
