Description
Allium \’Millennium\’ is a bold and striking ornamental onion cultivar prized for its large, globe-shaped flower heads of deep violet-purple blooms that rise on tall, sturdy stems. Blooming in early to mid-summer, the densely packed flowers attract pollinators such as bees and butterflies, adding life and movement to garden borders. Its architectural form and rich colour provide a dramatic vertical accent in mixed borders, cottage gardens, and contemporary plantings. Easy to grow from bulbs, it is low-maintenance and performs well in well-drained soils, making it suitable for naturalising in perennial beds. This variety is valued for its long-lasting flowers and strong structural presence, creating visual impact with minimal effort.
