Yes, here it is also the most usual method of planting - from seed tubers. Only in recent years (Thanks, Tomatoville et al!) have I begun to learn about the benefits of true potato seeds. I might get some for my mom as a Christmas present - she, as most Finns of older generations, loves potatoes and would eat them every day ... (Low carb dieting never has a chance with her, not that she needs to lose any weight with the active lifestyle and gardening!)
Our varieties this year: Van Gogh (an oldie goldie)
