Salvia or Nepetia?

in Plants
I wonder if anyone can identify this herbaceous plant I grew from a cutting. It's past my waist, very strong aromatic large leaves and not Nepetia 6 hills giant, it's taller and the leaves are a lot bigger too.

I think a nepeta. N. parnassica is very tall
In the sticks near Peterborough
Didn't Monty plant some of those in Friday's program?
Thanks everyone who replied so far. Unfortunately it's none of the above although it is most similar to N. Sibirica. With my plant the flowers grow upward like tiers on a cake and are present at a leaf joint. I've measured it and after 2 years it's just over 100cm
Wow how far out can I be, it was Borage that Monty planted
and to top it I' have it in the garden
