Wow! Is it Cortaderia selloana, or some other species? Does it actually winter over for you there?

Good question. My understanding is that Pampas is not hardy, even for zone 5B, where I live. I hope that someone can correct my on this one. This definitely looks like Cortaderia selloana.

Lori and Jroot,
Yes, it is cortaderia selloana. The picture above that is titled 'pumill and castor' is of course 'pumila'and the large one is 'sunningdale silver'. You are right that it's not hardy here in zone 4, but with a little extra effort and some finger crossing we've managed to get some through the winter for the past few years..

Amazing! Well done, kicker. I think I might just try it again. I did have some in Rockwood, at my old house, one summer. It was beautiful....sharp as a knife...but beautiful. All of it died in the winter.

What is the "little extra effort" that you do? I am VERY interested to know. Feel free to email me.
