When should I plant Allium 'Millennium'
I know many Alliums are bulbs that are planted in the fall, but is that the case with this hybrid or is this type planted in spring? I live in planting zone 5.

Although many alliums have growth cycles that make fall planting the right time, Allium 'Millenium' (spelled with a single "n") isn't that kind of a bulb. It can be planted anytime. However, if you buy it as a dormant bulb (not growing), then it should be planted in the fall.

I had a similar question and learned that Allium Millenium is a rhizomatous or clumping Allium rather than a bulbous Allium. Rhizomatous Allium cultivars like Millenium are generally available as potted plants starting in spring, rather than bulbs that are planted in fall. The rhizomatous cultivars do not go dormant in summer as do the bulbous types.

Thanks to another member, Sooby (Sue), I was directed to the following website, hosted by the hybridizer of Millenium and other rhizomatous cultivars:
