The 2018 Perennial Plant Association's Plant of the Year® is Allium 'Millenium'.
From breeder Mark McDonough comes this top-selling, award winning perennial allium. Its clump-forming, shiny deep green, strappy foliage is topped with showy 2" round, amethyst purple flowers in midsummer to late summer in zones 4-9.
This perennial offers everything today's consumers are looking for: deer and rabbit resistant, low water use, long blooming, hardy perennials that deliver a strong garden performance reliably every year.
Allium ‘Millenium’ is a butterfly magnet. The plant is interesting through multiple seasons for both foliage and large, gorgeous blooms. Reseeding is much less a problem than in other alliums.
