Blooming in late summer, this ornamental perennial onion, with its pink, clustered flowers and slightly twisted, strapping leaves, is the perfect addition to the rock or herb garden. Not only is Allium cernuum long lived, but its clumps multiply, so it can be divided after a couple of years to provide additional plants. Allium cernuum grows to about 10 inches in full sun and is sure to please. Zones
Allium senescens glaucum (syn. Allium spirale)
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 interesting 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.
