Allium senescens glaucum (syn. Allium spirale) (Curly Chives)
This is not an illustration of Curly Chives, but a different Allium that will hold a place until I have a photo that does this interesting Allium justice. Clump-forming, albeit very slowly, Allium senescens glaucum (syn. Allium spirale) has grey, spiraled leaves and pink flowers. I don't know this for sure, but I would say that the name "spirale" comes from the fact that the clumps grow in a spiraled fashion, which is very attractive, not to mention unusual. This Allium only grows from eight to 12 inches, so it is ideal for alpine and rock gardens. Sun, Zones 3-9. Quarts.
