Jerusalem artichoke
Prior to the introduction of the Three Sisters, the Massachusett were part of the Eastern Agricultural Complex, which included the spread of domesticated varieties of several crops which include goosefoot, marsh elder, erect knotweed, little barley and maygrass. Only the sunflower, Jerusalem artichoke and tobacco, the latter used for important ceremonies, remained in cultivation, although wild-type variants of the former crops were still gathered from the forests and fields.
