Potatoes or taters in Hobbitish, were root vegetables that were apparently among the staple foods of the Hobbits (Hamfast Gamgee was recognized locally as an expert on growing potatoes). Samwise Gamgee expected to find them in Ithilien.
Since the potatoes are a New World plant (see below), it has been suggested that "potatoes" is perhaps a "translation" from a Westron name of a related but otherwise unrecorded plant of Third Age Middle-earth.
Fans have noticed that potatoes are a New World plant, not native to the Old World setting of Middle-earth. The pipe-weed (another New World plant) is referenced as having being brought from Númenor and fans have explored the possibility that this was also the case with potatoes.. The Children of Húrin mentions that the Dwarves of Beleriand boiled a white fleshy root similar to bread which could have been another instance of potatoes in Middle-earth, from the First Age.
