Description
Allium 'Millennium' is a striking perennial known for its large, spherical flower heads composed of dense clusters of pale pink to purple florets. It typically blooms in early to mid-summer, providing an architectural interest to garden borders and containers. This herbaceous plant has a moderate growth rate and reaches a manageable size, making it suitable for a variety of garden settings.
Preferring full sun and well-drained soil, Allium 'Millennium' is generally hardy in most UK gardens, offering reliable seasonal interest.
