Strangely I never compost potato peelings, my mothers advice
some 55+ years ago. She said that potatoes would grow from
them. I'm sure it is one of those old wives tales, but such
long held habits are hard to break.

Years ago we had a huge compost heap used for any garden or kitchen
waste. Potato peelings often resulted in some potatoes growing on the
heap. The tubas they produced were perfectly edible.

Did they play a tune as well?

Potatoes would be a pernicious weed if they were not edible!
Not quite in the league of horseradish but not so far off.

Apart from volunteers on the site of former potato crops, potatoes are a
relatively infrequent casual, and in my experience tend not to persist
on any one site. So, I don't think that they would qualify as a
pernicious weed.
