Herre is a list of Cold Hardy Peaches that we grow here at Royal Oak Farm in Zone 5(4b) that have survived -25 below zero and fruited:
Cold hardy peaches: (Ripe date: +/- from Red Haven)
Contender (+18) - has high chilling
requirement (1050 hrs) & very hardy
fruit buds.
Cresthaven (+24)
Garnet Beauty (-11)
Harcrest (+26)
Madison (+24) - buds very hardy, but fruit
is tender & does not pack/ship well.
Redskin (+29) - bloom (& harvest) is
spread out, providing more frost
hardiness.
Reliance (+3) - reliable cropping, but poor
quality fruit
Here are two new varieties that we have not tried yet:
Summer Serenade (sport of Garnet Beauty)
Autumn Star (+ 45) - new cultivar, 2003;
very hardy fruit buds, but very late!
