No, and sadly it hasn't survived the winter, but that was the name it came with, in the middle it was green(where leaf stalk ends in the leaf), and the veins were green, but just a few cm, the rest of the veins was black.
Name: Evan Pioneer Valley south, MA, USA (Zone 6a)
I'm sorry it didn't survive snarfie, unfortunately they don't develop large tubers for me either. That description does match one of the dark forms of Illustris. Thanks.
