Wild potatoes are species other than the common potato (Solanum tuberosum) that can be used in breeding work with common potatoes. Some of them impart pest or disease resistance when crossed to S. tuberosum. Most are not edible, at least not without processing. They aren’t particularly dangerous, but contain high levels of glykoalkaloids, which are the same substances that make potatoes bitter and poisonous when they turn green. Some of them, such as S. acaule and S. chacoense may hold some potential as foods with some breeding work, but most are only used for cross-breeding with the common potato. In most cases, we sell the species, not any particular variety. You may get tubers of different phenotypes in the same packet.
