I heard a bawdy folk song at a Morris Ale in New England about ten years ago, about a gardener's wife. There were all sorts of vegetable metaphors, including one about "his raddishes" and "her turnips".

Sadly, I can't recall anything else. I can't remember any part of the chorus or even if The Gardener's Wife was the actual title. But if there's some other bawdy song with vegetable metaphors, I'd want to learnt about that too.
