I have a peach of unknown origin growing here in zone 3. I plant every
peach pit I get a hold of and this one has withstood -35 degrees. It hasn't
produced any fruit yet and I'll let you know what it does, when it does.
I have grown Sib-Cs here all of which have been plagued with Peach Leaf
Curl, a problem not affecting this new mystery peach.
