Pumpkin is a gourd-like squash of the genus Cucurbita and the family Cucurbitaceae (which also includes gourds). It can refer to either species Cucurbita pepo or Cucurbita mixta, and sometimes to a specific variety of either the species Cucurbita maxima or Cucurbita moschata. The word pumpkin originates from the word “pepon” which is Greek for “large melon.” The French adapted this word to “pompon,” which the English changed to “pompion” and later American colonists changed that to the word we use today, “pumpkin.” The origin of pumpkins is not known, although pumpkins are thought to have originated in North America. The oldest evidence, pumpkin-related seeds dating between 7000 and 5500 B.C., were found in Mexico. Pumpkins are a squash-like fruit that range in size (less than 1 pound to over 1000 pounds), shape, color, and appearance (smooth or ribbed).
