way too early for S officinale - and also seems too short. S officinale v rarely occurs over in the east: more of a fen edge thing with us.
... aren't the calyx lobes too shallow for Symphytum officinale?
but yes, they are.
Going through the old records it is very interesting to see how much better we are all getting at plant ID as the years go by!
I saw your comment and agreement because I'd added this one as a favourite because I didn't know what it was back in 2013. I still find comfreys reasonably difficult, but I know to take a note of the calyx lobeing and leaf decurrence to check against a book when I get home. (Symphytum orientale is one of the easier ones, but there's is a colony of white comfrey with deep lobes and non-decurrent leaves not far from my home that has been puzzling me. Inconveniently it usually gets swallowed by a colony of bracken before maturity, but this summer I found that some of the plants did have mildly decurrent leaves, so I'm tentatively concluding a white form of Symphytum x uplandicum, rather than something as novel as Symphytum asper x officinale x orientale.)
post pics if you can this summer - one of my friends is the national referee so could get him to look at them. He is very interested in seeing specimens of any of the larger white/cream comfreys of possible asper-officinale parentage which might have yellow or cream-coloured buds. S x uplandicum does cover a multitude of colours, but isn't often white, so it might be an interesting hybrid/back-cross.
Maybe you'll have to trim round it this year and see if you can get it to reach maturity unimpeded.
