This is allium senescens. I bought it unlabeled at a plant sale four or five years ago and have since divided it up and placed it in every impossible spot in my yard–sunny spots in my super-sandy soil that are drained to a crisp by large trees.
No complaints, ever. This is not a bulbous allium, but a clump-former that's best divided with a shovel. The flowers are numerous but by no means spectacular, in a ghostly purple-white color. However, the strappy foliage and round shape of the plant are just nifty, offering crisp contrast to everything else in my borders.Posted by tldd1103 on July 30, 2010 at 8:02 am, in the category It's the Plants, Darling.
