Flavourless mint

I have inherited an existing mint plant growing in the ground. The problem is the mint flavour is barely detectable. I've had look around the Internet and there is a possibility that cross pollination at some stage has caused this. Before I get rid of it does anyone else have another suggestion?

Mint is so easy to grow that I too would not bother trying to rescue one that I didn't like the flavour of. Most gardeners have mint, I would try and find a neighbour who will let you try theirs for flavour and then give you a root. It will establish in no time.
