Allium Millenium forms a clump of narrow green leaves topped by rose-pink flower globes in midsummer. Bees and butterflies visit the blooms, and the sturdy stems also provide long-lasting cut flowers.
Place this ornamental onion in a sunny border, gravel garden, or patio container where soil drains freely. Deer and rabbits tend to avoid its onion-scented foliage, while routine care stays limited to removing faded stems and dividing crowded clumps.
