Peaches: Will they ripen in a paper bag?

My supermarket had peaches on sale for 99 cents a pound, but as I sorted through them I noticed that they were all hard. I bought some anyway, and because I know that some types of unripe fruit will ripen more quickly if placed in a paper bag that is then sealed I put the peaches in a bag and left it on my kitchen counter.

Are peaches among the types of fruit that will ripen if stored this way?

My experience has been-it depends.

If the fruit wasn't picked too green the bag/ethylene gas trick works-if it was picked too soon it rots before ripening.

More and more here we're seeing fruit that was picked too soon-sad.

Peaches

I have heard that if you want fruit to ripen store it next to ripe bananas.
Don't know the science involved.

...if you want fruit to ripen store it next to ripe bananas

I wish I had known! I have some ripe bananas in the kitchen right now.

If there is science behind it, I bet that ripe bananas emit ethylene.

Yes Bananas emit ethylene gas but ripen very fast in a paper bag while Apples ripen slowly.

Heard that bit about placing them near bananas too.

How did it work out?

I put the peaches in a paper bag on July 1, the day I purchased them. I opened the bag on the 3rd, and noticed that they had a fragrance and "gave" slightly when pressed. I will use them later today as ingredients in a coffee cake. Had I known or suspected that bananas might have accelerated the ripening process, I would have put the bananas in the same bag. Instead, the bananas were on another part of the kitchen counter.
