Lilac Sunday

Named in honor of the beloved annual Lilac Sunday celebration at Boston's Arnold Arboretum, this exceptional variety lives up to its festive namesake in every way. Lilac Sunday is one of the most prolific bloomers in the lilac world, producing an almost overwhelming abundance of soft, rosy-pink to light purple flower clusters that smother the entire shrub in mid-spring. When in full bloom, it is quite simply one of the most breathtaking flowering shrubs you can grow. As a hyacinthiflora hybrid, Lilac Sunday blooms 7–10 days earlier than standard French lilacs, extending the lilac season and making it an ideal companion plant alongside later-blooming varieties for a continuous spring fragrance display. Its slightly looser, more open flower clusters give it a romantic, informal charm that feels equally at home in a cottage garden or a formal landscape.
