About this plant
Allium 'Millenium' is a robust perennial known for its rounded clusters of vibrant purple-pink flowers that bloom midsummer through late summer. The long-lasting blossoms are held on sturdy stems above clumps of glossy, deep green foliage, providing a burst of color during the growing season's peak. These nectar-rich flowers are highly attractive to pollinators, drawing bees and butterflies to the garden.
This hybrid allium was developed to showcase reliable performance and ornamental appeal, making it a favorite among gardeners. It is well-suited for perennial borders, rock gardens, or as an accent in mixed plantings. Its tidy habit and resistance to deer and rabbits make it an excellent choice for various landscapes.

Design tip
The long summer show pairs well with plants that peak earlier, keeping one area interesting for months. Drift them in uneven groups for a natural look, and interplant with perennials that fill the gap after the leaves die back.
