Often if I've eaten a particularly delicious Peach, I plant the stone. They grow very quickly.
There is no guarantee of success, but occasionally one comes up trumps.
I've had trees that produced almost identical fruit to the donor, and I've had others that produced nothing.
These Peaches above come from one such tree, and although they're very small, they are delicious.
They seem to be especially small this year, probably because we've had no rain, but their flavour beats almost all other peaches. No juice running down my bearded chin, but otherwise just about perfect.
If you have the room (and the climate), may I suggest you do likewise, apart from anything it's fun to see what they produce.
