"Midnight sun, Taiga, True Colours and Tundra, all potato leaf hearts bred and stabilized by me, in Canada and released in 2019 and 2020.
They were bred and selected in zone 3 at around 2400 feet above sea level in Alberta Canada. They are fairly early for large hearts and unusual in their colouration on a potato leaf plant. They were specifically bred to do well in my own Canadian garden and they have shown themselves to be quite tolerant of most conditions in the short time since their release. "-Tells the author of this breed and breeder Karen Olivier.
