Culture area

In the Northeast culture area, the agricultural base for many Indigenous peoples consisted of a combination of crops known as the "Three Sisters": corn (maize), beans, and squash.12

In addition to these primary crops, farming groups also cultivated weedy seed-bearing plants such as Chenopodium. This agricultural system was particularly essential for groups in the central and southern parts of the region, where wild food resources were less abundant than in the northern or coastal areas.12

The Three Sisters were often planted together in small mounds, a practice that allowed the plants to support one another: the corn provided a natural trellis for the beans, the beans helped restore soil nitrogen, and the large leaves of the squash plants helped retain soil moisture and suppress weeds. These crops were vital for food security, as they could be dried and stored for winter consumption.32
