collecting siberian peaches from various sources to trial. siberian c isn't exactly a cultivar, it's a seed strain with a certain set of characteristics like cold hardiness, late ripening, generally firm fruit with some yellow / green tinge to the skin. every source for these has some genetic variation depending on hybridization, and selection pressures. most sources for them are in warmer zones, 4-5. hoping to get a population growing here and really trial them in zone 3 to see if we can select for the best cold hardiness.
