Allium 'Millenium' is one of the best recent introductions of Ornamental Onions - so good we crowned it our Perennial of the Year! This neat little Allium produces rounded heads of light purple, star-shaped flowers atop stiffly, upright stems. The slender, grassy foliage forms a dense clump that covers the base of the flower stems nicely. Allium ‘Millenium’ is at its finest when planted in generous groups in sunny borders. Height: 60cm (24"). Spread: 10cm (4").

Alliums thrive in light sandy, well drained soil in full sun. Avoid planting in cold wet soils as they are prone to rot in these conditions. Plant alliums at a depth of 10cm (4") and a distance of 10cm (4") apart. A slow release fertilizer can be added to poor soils at the time of planting to improve fertility. When growing alliums, plant them where the leaves of other plants will cover the base of their stems. This will hide the old foliage which dies back before flowering begins.
More Info Alliums require little maintenance. Leave stems of faded allium flowers intact to enjoy their spectacular seedheads in autumn. Divide overcrowded clumps of alliums after flowering.
Caution Caution: irritant to skin and eyes
