Thank you all for the input. I will share with my neighbor. Fortunately she doesn't live right next door or I might have some artichokes. Lol! This plant has obliterated her front yard and made the other prettier plants look like they're in a jungle. Guess that's why she's determined to get rid of it. (And yes, her front yard does look like a jungle!)
What part of the plant do you eat? Guess they're like greens?
Thanks again.
