The Perennial Plant Association’s, 2018 Perennial Plant of the Year (POY) is none other than Allium ‘Millenium’. This fantastic, low maintenance, hardy perennial provides interest year round! And if you haven’t already guessed, it is one of my sun loving favorites! Glossy, grass-like green foliage creates an attractive plant, even before the rose-purple globes begin to bloom mid-summer. The abundant long-lasting floral display is favored by pollinators and butterflies, while it repels deer and rabbits with its pungent onion flavor. As autumn approaches, the sturdy flower stalks of ‘Millenium’ go to seed. Not only do these unique seed heads create wonderful interest in winter, but they also provide a nice treat for our feathered friends. We linked to a fun video by Walters Gardens, Inc on our Knecht’s Facebook page. They did a very nice job featuring this year’s POY winner. Be sure to check it out!
Know to grow: Allium grows in a wide range of well-drained soils from poor to fertile. With a mature height of 15-20 inches, they provide a versatile addition to landscapes and perennial borders. While they prefer full sun, light shade is also acceptable. ‘Millenium’ would grow nicely with other late summer favorites of similar size, such as Little Lemon Solidago, dwarf garden phlox, or Rudbeckia Goldsturm. Consider planting with annual white Lobularia or Alyssum for a stunning combination!
