  • There has been a lot of conflicting information / confusion about the origin of this tomato.
  • First offered in the Seed Savers 2005 Yearbook by Dorothy Beiswenger, Crookston, Minnesota (MN BE D), who said she got the seed from a seed saver, who discovered this yellow large tomato on a Pruden's Purple plant. Dorothy did not mention leaf type.
  • Up to date (2011), no other SSE members re-listed this tomato in the SSE Yearbooks, but many growers obtained the seed from Dorothy Beiswenger, including Bill Malin of New Mexico, who later shared it with others describing it as a 'potato leaf' variant of Black Krim, and that Dorothy discovered it and named by her for the Flathead River in Montana where her grandparents homesteaded in the early 1900s. This story does not match Dorothy Beiswenger's SSE listing.
  • Some growers who got seeds from Bill Malin reported black fruits, and some reported orange and pink fruits. Either the original seeds have been crossed, or a new cross appeared in Bill Malin's garden.
