Barrel cactus

Barrel cacti are a species of cactus comonly found in the southwestern North America, easily recognizable thanks to their distinctive shape and dense rows of needles. Relatively easy to cultivate, hardy, and long-living, barrel cacti have adapted well to the post-nuclear climate and have been cultivated by wastelanders for decoration and its fruit, which is used as flavoring in salads, home-brewed Nuka-Cola, and various tribal remedies.
