I am saving a bunch of potatoes, to become next year's potato plants. Potatoes can sprout and root, giving the plant the ability of asexual reproduction, Since a potato is an exact genetic clone of the plant that made it. This means all the russets that are sprouting in my closet have the EXACT same DNA as the russet I started in March. Potatoes also produce flowers and seeds, but most farmers start the next year's crop with the smaller potatoes from the previous year, called "seed potatoes" to ensure it has the same genes.
As well as russet, I am also trying "Yukon Gold". Yukon gold is a yellow flesh potato. I obtained mine from local grocery stores and Hanson's Farm. My largest one, for some reason, has been absolutely exploding with sprouts. All my other potatoes are slowly getting greener and greener, and are still pretty much dormant, While the "Yukon Giant" keeps progressing toward becoming a green, leafy plant. In November. I am worried that I will have a massive, demanding potato plant in the fall, And will not be able to take care of it all the way up to the spring. The smaller, more dormant potatoes in my closet are much more manageable. I will say, though, that watching the Yukon Giant develop has been interesting.
