Man they are just the ugliest flowers. But that is cool.
Didn’t realize they grew so well in pots.

What zone and hemisphere are you in? I’m guessing Northern and somewhere it gets cold(er)? We’re zone 6a and I left our first year globe artichokes in the ground more or less as is. They’re not brown, but they don’t look that happy after a few hard frosts. I’m surprised to see what looks like new growth on yours combined with the brown.

I can’t tell what I’m looking at. Did you get any artichokes?
