a new seed lot of siberian c peach for our trial

a new seed lot of siberian c peach for our trial. now 5 sources of the cold hardy peaches have been collected, all growing in zones 4-5 from ontario and quebec, with a range of reported ripening dates, and some differences in the seed's appearance. we're hunting for the real deal, the most cold hardy peach. While these are around in Canada, I have yet to find a source that is known to actually survive -35 to -40C so this trial will grow out 25-50 of each source and see what happens, which ones handle our prairie winter. It's possible that you can only fruit them in zone 4, but given anecdotes and how variable winters can be, it's possible that in the right location they can fruit in Manitoba/Saskatchewan/Alberta. If you have a peach tree and you're in zone 3 reach out please we're interested to know.
