Millenium Perennial Allium
There's good reason this was the 2018 PPA Perennial Plant of the Year—this allium is truly one of a kind. It's a little shorter, smaller and later blooming than many other varieties, and it forms perfect purple orbs. At this size, it'll fit nicely in the front row of a border and be the first thing visitors see. Modern-looking and fragrant, it'll stand apart from all those traditional flower forms, and get all the compliments. The lovely scent is nice in fresh floral arrangements. A dream for beneficial pollinators, but usually of little interest to deer.
