Old Glory is an early-blooming lilac cultivar developed by the U.S. National Arboretum, notable for its abundant, fragrant bluish-purple flowers and robust disease resistance. Blooming approximately 7 to 10 days earlier than common lilacs, it extends the lilac season and provides a reliable floral display even in warmer, humid climates.

Key Features:

• Fragrant, bluish-purple flower clusters bloom in mid-spring

• Rounded, multi-stemmed shrub reaching 8–11 feet tall and 10–12 feet wide

• Foliage bred for resistance to powdery mildew

• Attracts butterflies, bees, and hummingbirds

• Hardy in USDA Zones 5–8

Old Glory lilac is an excellent choice for gardeners seeking a low-maintenance, disease-resistant shrub that delivers early-season color and fragrance. Its adaptability and ornamental appeal make it suitable for various landscape applications, including borders, hedges, and specimen plantings.
