Progressive is an ever-bearing strawberry listed in the South Dakota Fruit Garden recommendations with Gem, Mastodon, Wayzata, Lockhill, and Dry Weather.[S1] [S2] In these sources, it appears in the strawberry section rather than in a full cultivar profile. The surviving evidence here identifies its fruiting habit more clearly than its breeding history or fruit details.[S1] [S2]
The strongest context for Progressive is regional adaptation. The South Dakota circular was written to guide home fruit planting in demanding prairie conditions, with repeated emphasis on hardiness, local suitability, and dependable performance.[S1] [S2] In that setting, Progressive was included among the ever-bearing strawberry varieties considered suitable enough to recommend or discuss for South Dakota growers.[S1] [S2]
These sources do not give parentage, breeder, place of origin, fruit size, flavor, season beyond the ever-bearing habit, or plant habit details for Progressive.[S1] [S2] They do place it in a mid-century northern fruit-growing context focused on practical garden performance rather than catalog romance. That helps explain why its documented value here is simply that it was recognized as an ever-bearing sort worth naming in a cold-climate extension guide.[S1] [S2]
