I think it may be Salvia guaranitica.

It looks like Salvia patens, but it just as well could be another. Were the individual blooms rather large (for a Salvia)?

blue and black salvia ? not sure of the other name it starts with a "G" hope that might help

It doesn't look exactly like S. patens to me, but I'm not positive. I am sure, though, it's not 'Black and Blue', which has black sepals. Isn't 'B & B' a cv. of guaranitica?

I think it's Salvia Azurea. Check out this link and see if this is it.
