Lamiastrum galeobdolon, not one you want to introduce into your garden unless you have a lot of space and don't mind a thug in the shrubbery.

Thanks for the info... It's in a pot will discard since it is invasive & I don't have the space on my balcony ;)

And not a vine at all but a member of the mint family with a rather lax habit. Spreads by root and stem fragments, rooting at nodes and by seeding.
