It took a while but I was finally able to locate a UFBest peach on floriguard rootstock.
I'm reasonably confident that this is the real deal.
I found three tags with the same name between the tree and the soil.
Got it from home depot a few years back.
I'm probably going to get rid of this in a year or two, even it took a while to find.
The reason is fruit fly larva.
Anyways the tree is budding out now so if anyone wants some LMK
$2 per scion, minimum is 10 pieces.
shipping is $8 for a flat rate box.
US only.
