Sadly mine is a bocking variety so not invasive, I would love the invasive kind, it is one of the best high protein forage for chickens and rabbits!!!! I would want it to take over the whole 1/3 acre the chickens and rabbits inhabit.Beautiful photos. I have ranted about my battle with comfrey before. It is horribly invasive. I know there are some varieties that are not. I hope that is what you have. Cut the blooms quickly after they bloom and do not let it reseed. Never till it. each bit will turn into a new plant. It is enticingly lovely.
Yes I will post a pic of the whole plant but it will be later this afternoon at the earliest
I ran out of time and steam today, here is a link w/ info and pic of the full plant. https://en.wikipedia.org/wiki/Comfrey
