Comfrey or Borage?

[InfraDig]

I think this is "Russian" comfrey:



and I always thought that this was a comfrey too:



but a friend is telling me it is borage. Any ideas? Thank you very much.

I'm confused the blue flower says borage to me but my comfrey has a purple flower  ???

our borage has star shaped flowers, the leaves taste of cucumber, don't know if it helps  ;D

I've got lots of borage seedlings coming up and the leaves are lighter green and more rounded than my comfrey, but I guess varieties vary?

the blue flower is Alkanet, or rather Green Alkanet. In the Borage family, along with Comfrey

That's definitely Not borage. This is borage: http://en.fotolia.com/id/4170200

Comfrey is very free in its colour of flowering.   It grows wild around here and comes in all shades of pink, purple and blue and the occassional white.  Often they change colour as they open so the young flowers are pink and the older ones blue.

The white flowered plant in the first photo looks like comfrey but it does not look like russian comfrey it is more like either Symphytum Album or possibly Symphytum Orientale.
The blue flowered plant in the second photo is almost certainly green alkanet.
