Potato 'Cups'

Medium - small, round tubers, white flesh, silvery-pink skin, originally from William Woys Weaver, of Devon, PA and author of "Heirloom V...Read Moreegetable Gardening." Weaver indicated his source was the Beamish Museum in County Durham, England. Rare variety, pre -1770. GREAT GARDEN POTATO! I particularly like the crop of this cultivar - most tubers are in the 2" across size, few grow to 3" - out of my standard 3 ft. row I harvested half a 5 gallon pail of tubers. The tuber in the picture was harvested the first week of July but the vines were done in October, when I found lots of small tubers and very few larger than 2". The perfect small potato. In 2009 I've received a few tubers of Black Mignion from AgriCanada. Seems to be identical to Cups. More information can be found by googling Kenosha Potato Project.
