There used to be a clump of cardoons that would come up every year in front of a restaurant in this area. I just found 2 plants at a nursery and am wondering how I can protect them over the winter.

You can cut them down to the ground and put some mulch on over them... if it warms up in the winter be sure to give it some water. You can also dig them up in the fall and pot them, then plant in the spring. I found a video on you tube that talked about saving seeds for Cardoons and Artichokes but it had lots of other great info like digging them up and potting.
