Very common in France if you ever drive by. Usually sold as a small 30cm^3 plant which will probably grown up to 1.5m in diameter the first year. I used to have 7 in 12m2. It’s also possible to grow from seeds, which you can buy online. It will require some dedication.

IME a very easy perennial, if you can prevent drought. Plant and forget. Like artichokes.

From what I know, not everywhere in France but in the north. It was impossible to me to find this month in Occitane, at least.
