Ancient Seeds are rare artifacts that can be found by digging up artifact spots, as well as in treasure chests or by fishing. Once donated to the museum, players receive a plantable version and a recipe to convert any further seeds into plantable ones. When cultivated, these seeds grow into Ancient Fruit plants, which bear fruit every seven days and can be harvested in all seasons except winter if grown in the greenhouse.
