Anyone recognise these mints

1) variegated mint - I think that the leaves are too narrow for ginger
mint - being grown on an allotment

When I used to grow one like that, I knew it as pineapple mint. That
doesn't mean to say it was right!

The one I bought as ginger mint had leaves the texture of apple mint
(though a lot smaller) and white rather than gold variegation.
