This deciduous shrub exhibits an upright, multi-stemmed habit with dense foliage, making it a classic choice for borders or ornamental landscaping. Hardy in USDA Zones 3-7, it thrives in full sun and well-drained, slightly alkaline soils, tolerating temperatures down to -40°F. In spring, it produces abundant clusters of fragrant, lavender-colored flowers that attract pollinators. The foliage transitions to a mellow yellow in fall, adding seasonal interest. It matures to a height of 8-12 feet with a spread of 6-10 feet. Deer resistant and drought tolerant once established, it is ideal for cottage gardens or hedges. Its neat, rounded form makes it as attractive in structure as it is in bloom.
