Allium ‘Millenium” Perennial Plant of the year
Allium ‘Millenium” (note the one “n”) adds a brilliant pink-violet highlight to the summer garden. It’s a real butterfly magnet. This perennial pick of the year by the Perennial Plant Association is a tried and true performer. Unlike spring blooming alliums, ‘Millenium’ puts her show on in July and August, just when many other plants are beginning to lose their lustre.
In the early part of summer, the plant sports glossy, deep green, grass-like foliage that rises six to 12 inches above the ground and makes its own ornamental statement. After blooming, the attractive seed heads can be left in place as this variety does not self-sow to the same extent as some other hardy allium.
The ball-shaped, two-inch diameter flowers grow on scapes that reach 18 to 20 inches, their violet tones set off well by low-growing Coreopsis lanceolate which will populate the garden from May to August in neat clumps and also attracts butterflies.
Allium is not particularly attractive to either deer or rabbits.
Be sure to give her plenty of sunlight although a bit of welcom Allium light afternoon shade will be ed.
