This deciduous shrub boasts an upright, multi-stemmed habit and is celebrated for its stunning, double lavender-blue flowers that bloom in late spring, filling the air with a lovely fragrance. With a recommended hardiness of zones 3–7, it thrives in temperatures typical of these regions. It grows best in well-drained, fertile, slightly alkaline soils and reaches a mature height of 10–12 feet, with a spread of 6–8 feet, forming a rounded shape when mature. While it displays no significant fall color, its lush green foliage serves as a backdrop for the showy flowers. Deer resistant and moderately drought tolerant once established, this hardy plant is perfect for borders, hedges, or as a standalone feature in the landscape.
