Notes
'Millenium' ornamental onion (Allium 'Millenium') is a bulb for borders, pollinator gardens, rock gardens, and containers. It is hardy to USDA zone 5, or down to -20°F (-29°C). This plant likes full or part sun and dry to moist soil of most types. Its rose-purple blooms are fragrant and attract butterflies and bees. Deer and rabbits tend to browse other plants first. It is drought tolerant, so it needs little care.
Pairs well with Magnus coneflower, Anise hyssop, and Russian sage.
