When we say this lilac is a two-timer, we mean it in the nicest possible way! A revolutionary new kind of re blooming lilac, Our Bloomerang Lilac Shrub blooms in spring and then again throughout the summer. It is considered a dwarf lilac variety. It does go through a rest period in the heat of the summer, then flowers again. While traditional lilac varieties bloom for a few short weeks in spring, Bloomerang's fragrant flowers continue until frost. One of the best Lilac shrubs available.
