I’m in zone 5b in Illinois. I see you’re in Scarborough but I don’t know if that’s Maine or Canada. You might clarify that on your profile for everyone.
Here is that list of peaches:
Peach Picks for Aledo Illinois from Mark/Olpea August 2017
Considering you are farther north than I, my recommendations might be a bit different for your area, vs. what I might consider “must haves” for someone farther south.
If I lived in central IL, I’d probably plant peaches fairly hardy. The following peaches I consider hardy, produce the best in frosty springs, and taste good. From earliest to latest. Some of these are patented.
Earlystar- There are hardier early peaches (like Harrow Diamond) but I’ve found Earlystar somewhat hardy in my area and tastes considerably better than Harrow Diamond. Earlystar also performs fairly well in challenging spring weather
Surecrop- Good hardiness and excellent performance in poor spring weather.
Risingstar-Ripens a few days after Surecrop and tastes better. While Risingstar has performed well for me in frosty springs, it’s not performed as well as Surecrop after a cold winter.
Saturn-If you like white peaches, this is a sweet white donut I’ve found a hardy and regular producer
Clayton- I don’t have much experience with this peach, so any concrete recommendation would be pre-mature, but so far this one looks promising.
Redhaven- Hardy and reliable. This would qualify as a “must have” in my opinon.
Challenger-Not a lot of experience on this one either, but so far looks very good and it reported to be very hardy.
Allstar- Hardy here and very productive every year.
Glohaven- Ripens with Allstar, but not as hardy. Tastes better than Allstar.
Intrepid- I have very little experience with this one. I have about 5 trees of this one, but they are still young. I mention it because it may be a very hardy and productive selection. It was developed in the same breeding program as Challenger and Contender, and supposed to be as hardy. This may be a variety you would want to take a look at.
Contender-A must have for anyone in a colder environment.
Veteran-Ripens with Contender. Very winter hardy but not as big or red as Contender
Scarletprince-Not a lot of experience, but may be winter hardy and seems productive in frosty springs. High quality very tasty fruit.
Julyprince-A little more experience and ditto all the comments about Scarletprince.
Baby Crawford- Hardy and very productive here.
Madison-A lot like Veteran, but ripens a week later
PF25-Hardy and productive, larger than Madison.
Redskin-Lots of experience with this one. Hardy and very productive. Doesn’t color very well.
Encore-Hardy and fairly productive, but have had trouble getting this one to reach acceptable levels of sugar.
PF35-007-Hardy and very productive. Good flavor. A very quality late season peach.
Maybe that’s more recommendations than you wanted, but I think any of the above would be suitable for your area.
And edits to that list coming from Mark/Olpea
Glohaven Zone 6A or above. Too much bud kill in Kansas.
Clayton Zone 6A or above. Too much bud Kill in Kansas
