Thanks. Just looked a bit like it was bolting.

It will do, it wont hurt it. bees like comfrey flowers, just make sure they are purple, and look like upside down trumpets.
Whilst it's establishing let it go through its life cycle. Don't harvest any this year. You'll want all that energy going into the root system.
It looks like Bocking 14, wild comfrey tends to be a bit stumpier.
