Artichoke or Cardoon

Hi, wonder if anyone could identify these for me. I have tried looking online but can't decide. I was told they were artichokes but to me they look more like Cardoons.There is a big bed of them in the garden but don't know anything about them. Anyone any experience of these?

I'm going with artichoke which also grow tall, both because of the leaves and the heads in your picture.

Both are edible though.

They're Cardoons. Good luck with them. I grew some a couple of years ago. It'd have taken a nuclear reactor to cook them to an edible state

I have both for decoration only, the chokes are up to 120cm high and 15cm diameter heads while the cardoons go up 2mtrs but are only 8cm in diameter .

I wouldn't even bother thinking about eating a cardoon
