Juncus Big Twister

This plant I found out Wal-mart a few weeks ago. I'd never seen anything like it, so decided that I would give it a try and plant it in our garden. It mentioned that it will survive to -10 degrees, so I'm not sure if it will survive winter. It has these long, green corkscrew type spindles--in other words, I'm not really sure what they are called (laughing)!! I tried to find out some information about this plant by doing an Internet search, but there was not much information out there. It sounds as if it doesn't necessarily do well as a houseplant, and does quite well in wet soil. We shall see if it comes back next spring.
