Allium ‘Summer Beauty’ is a dependable ornamental onion cultivar valued for its rounded clusters of soft lavender-pink flowers and its tidy, clump-forming habit. Blooming in mid to late summer, this perennial typically grows 12 to 18 inches tall and produces glossy, strap-like foliage that remains attractive throughout the growing season. Unlike many spring-blooming alliums, ‘Summer Beauty’ provides color later in the season and performs reliably in full sun and well-drained soils. Its nectar-rich flowers attract pollinators, while the foliage and bulbs are generally avoided by deer.
