Allium ‘Millenium’


Allium ‘Millenium’ in the early morning light.

What’s not to love? This Allium hybrid from Mark McDonough is one of the key plants for solid bloom in July and August in our perennial and mixed beds. 2″ lavender orbs on sturdy 12-18″ stems provide color for weeks. It doesn’t mind the heat and dry soil, and  bulks up quickly, and can be divided in the spring if you want to spread it around. Of course it is attractive to butterflies and pollinators. When blooming fades, cut back the stems, or leave the heads on to dry and add textural interest. Deer and rabbit resistant and it is perfectly hardy in zones 5-9.

  1. does it self seed everywhere?

    • It is a sterile hybrid, so the answer is no, it doe snot self sow.

  2. Love these allium but wondering when I should plant. I’m in zone 5, northeastern Mass. Thanks!

    • Deborah, These can be planted anytime. We are selling live clumps, not individual bulbs.

  3. How many plants would I need to fill a 20″ round container?

    • Barbara, How quickly do you need it to be full? Another question is, are you living the container outdoors year round?

  4. Do the base leaves go to brown or stay green?

    • The foliage stays green all summer…not like the tall bulbous forms which brown out even before the flowering begins.

  5. and how are they divided..just dig up the baby bulbs and spread them around?

    • Deborah,
      they grow just like chives.
      Dig them up and divide the little bulbils in the fall or spring.
