Sweet Violets was apparently recorded by Mitch Miller and went something like this:

There once was a farmer who took a young miss
In back of the barn where he gave her a
Lecture on horses and chickens and eggs
and told her that she had such beautiful
manners that suited a girl of her charms,
A girl that he wanted to take in his
washing and ironing and then if she did
They could get married and raise lots of --

Chorus: Sweet violets, sweeter than the roses
Covered all over from head to toe
Covered all over with sweet violets.

(Guess I didn't misremember all that much after all!)
Didn't find the second or third verse on a brief Google, though.
The original song is, not unexpectedly but not very helpfully either, "traditional."

Did find that, while it's gently misleading to the hearer as to what the next word will be, it's really _very_ much cleaned up (had to be, I guess, to be a Hit Parade song aroung 1950) and what the violets were Covered All Over with was much stronger indeed...
