From the website Potato Garden, the early rose potato is described as, A true vintage potato from the 1860s that has stood the test of time and loved and enjoyed by gardeners for over a century. Early Rose has smooth pinkish skin and delicious white flesh streaked with red. Selected from self-pollinated seedlings of Garnet Chili by Vermont farmer Albert Bresee. The parent to the now world-famous Russet Burbank.

The reason you have just received this mini-lesson on the potato is because I happened along the following blurb published in The Fowlerville Review:
Daniel VanRiper exhibited some mammoth potatoes that he has grown this season, of the improved Early Rose variety. They are beauties.
