This is one of my favorite plants. They are extremely prolific, frost and drought hardy and easy to grow. I also love to eat them, they happen to be a fantastic forage plant because the goats love to eat the stalks but they don’t really damage the roots if you rotate them properly. The only con is they are a bit tenacious if you want to remove them from an area but it’s not that hard. Don’t plant them in your intensive garden because they are too huge and shade everything out
