These have been healthy and hardy in zone 4, ND. Sometimes I overwinter the plants for spring and fall production. Sometimes I just save the runner plants to replant the following spring, for fall berries. I was concerned about hardiness, but they have been fine. I mulch with straw and put spruce boughs over the bed for further protection. Soil pH is about 7.5 and these are not chlorotic here like Honeoye. Best flavor w 2-3 days of ripening once they turn red. But sometimes SWD fruit flies limit that. A CSA farmer told me they were too soft when grown near Minneapolis, but they are a very firm berry here in high Ca/Mg soils. I bought these from Pinetree after seeing good production notes from UMN trials at Grand Rapids research station, 4 or 5 years ago. Thx!
