Is comfrey supposed to look this happy?

I live in MN, and the picture was taken today. Should my Cumfrey look this happy where it's at?
It's on a pasture with a creek running next to it with super-black dirt, and the rhubarb near it isn't doing nearly this well.

The posts behind it are bird house posts that are maybe 8 feet tall.

The leaning post is probably only being held up by cumfrey roots.

Does anyone know what bocking this is?

My established comfrey is about 4 feet tall. I don't fertilize mine at all.  Mine is even wider than yours. I think comfrey just likes to get big? My plants are 11 and 8 years old (planted on my kids' first birthdays).

I'm not sure what type of comfrey mine is (mine is blocking and has purple flowers, and I got it from a local permie and didn't ask what type it was). Hopefully someone else knows comfrey better and can tell you what type you have!

I went and reminisced on my old thread, and noticed that, after just one year, my comfrey was already taller than my 2.5 year old!

My experience is that comfrey LOVES damp roots. I planted root cuttings from the same mother plant in my own garden on fast draining chalk soil, and at my in laws which is low lying flood plain with a very high water table. Their one needs to be cut multiple times per year and perfectly supresses the weeds around their apple tree. My ones limp along and get one cut. I think they would need irrigation grow vigorously.

Happy comfrey is okay ...

my comfrey seems to be happy out of sync with my other plants too. not sure why. I almost never water it, so it seems to be on its own time. it only really looks terrible when it's cold and dry.

Yeah comfrey really does love wet feet. Mine is in a spot that gets boggy after rain and it's enormous compared to the one I planted in a drier bed. The damp one just keeps going all season, the other one sulks a bit in summer.

Since I'm not really good at  the chopping bit of "chop and drop", my comfrey can get pretty tall also, and the bees are happy for the blossoms. The areas it's happiest have had slow by steady soil improvements with weeds/mulch/wood chips, but it rarely gets water.

It is least happy in a pot by the shed where it is not only not as tall, it can totally droop in an hour if I forget to water it for a day too long! I had left some in a pot in the hopes I could get another fruit tree planted, but that's not happened, so it will need to rely on me at least until the fall.

That's how big my comfrys get after 3 years of being left alone. Two years if i give them some half bucket of manure when i plant them out. I got a lot and use it as a border to keep grass from invading and i use 3 year old roots to make balms with together with rosemary, eucalyptus, mint, arnika, camomille, sage, ginger . It's a banger. Lately my friend hurt his wrist after overdoing rendering. We thought we'd lost him, he warned last time he injured himself like this it took 3 weeks of rest. We'd travelled a days drive to do a week of work, i gave him the balm, he put megadoses of it on and was back at it the day after. Finished the job. It's a miracle cure.
Best thing ever if you dig them up,i only use the big root to supply family and friends and more and more acquaintances they will leave roots in the soil and pop back up in a ring. 5 easily. Ready to transplant in autumn. I dropped some pieces of root on the path and they peek through the grass. Avoid self seeding ones and smaller runner ones and you're laughing the rest of your life.
