In 2007, I grew out some Green Giant seeds sent to me from Annie Neoh of California, but instead of getting a green when ripe potato leaf plant, the tomatoes ripen to yellow. Since the plant was potato leaf, I guessed that the plant mutated. I sent the seeds to growers in Australia, and their plants were also yellow fruited potato leaf. I named it Casey's Pure Yellow because it does not turn golden like many other yellow tomatoes. I believe there is only one other pure yellow, potato leaf beefsteak: Lillian's Yellow Heirloom. Sweet and incredibly juicy fruits can weigh up to 2 lbs. (900 g).

  • Discovered by Jeff Casey, Alberta, Canada in 2007 in a patch of Green Giant tomatoes that he grew from seeds sent to him by Annie Neoh, California. Instead of green fruits, the plant produced large yellow beefsteaks with clear skin, hence the name.
  • First offered in the Seed Savers 2009 Yearbook by Neil Gillard of Holland Landing, Ontario, Canada (ONT GI N), who received the seed from Jeff Casey of Airdrie, Alberta, Canada in 2008.
