I'm sure it would love to be in an unheated greenhouse. Ours are all planted out and they come through winter, without any extra protection but we have very mild winters in North Norfolk
Thanks for the video. Not many UK ones on artichoke. I am growing from seed for the first time. Leaves have gone big but there are not many and wind snapped a few leaves. I was looking for the other video you mention here during the growing season of artichoke- couldn't find it. Any suggestions would be much appreciated, thank you.
