Common comfrey

Since knowing comfrey is a great fertiliser I’ve got mad trying to spot on my walks. Is it right that the purple Russian varieties don’t flower yet? I found these today
on my fitness walk and on looking up I think it is common comfrey. Do others agree? Thank you

There are also forms of comfrey with purpley flowers and others with variegated leaves. They all die down in winter unless it's very mild and they all tend to start growing early in spring.
It can be quite invasive in a garden if not controlled. The Bocking 14 variety is sterile which at least stops it seeding.
