Eastern North American Neolithic
Archaeological evidence shows that eastern North America (often abbreviated ENA) was a separate place of origin for the invention of agriculture. The earliest evidence of low-level food production in ENA begins between about 4000 and 3500 years ago, during the period known as the Late Archaic. People entering the Americas brought with them two domesticates: the dog and the bottle gourd. Domestication of new plants in ENA began with the squash Cucurbita pepo ssp. ovifera, domesticated ~4000 years ago by Archaic hunter-gatherer-fishers, probably for its use (like the bottle gourd) as a container and fishnet float. Seeds of this squash are edible, but the rind is quite bitter.

Iva annua (known as marshelder or sumpweed) and Helianthus annuus (sunflower) were domesticated in ENA by about 3500 years ago, for their oil-rich seeds.

By 2000 years ago, Polygonum erectum (knotweed), Phalaris caroliniana (maygrass), and Hordeum pusillum (little barley), Amaranthus hypochondriacus (pigweed or amaranth) and perhaps Ambrosia trifida (giant ragweed), were likely cultivated by Archaic hunter-gatherers; but scholars are somewhat divided as to whether they were domesticated or not. Wild rice (Zizania palustris) and Jerusalem artichoke (Helianthus tuberosus) were exploited but apparently not domsticated prehistorically.

Maygrass and little barley ripen in spring; chenopodium and knotweed ripen in fall. By mixing these seeds together and sprinkling them on fertile ground, the farmer would have a patch where seeds could reliably be harvested for three seasons. The domestication would have occurred when the cultivators began selecting the chenopodium seeds with the thinnest seed covers to save and replant. By the Middle Woodland period, domesticated crops such as maize (Zea mays) (~800-900 AD) and beans (Phaseolus vulgaris) (~1200 AD) arrived in ENA from their central American homelandsÃ and were integrated into what archaeologists have termed the Eastern Agricultural Complex. These crops would have been planted in large separate fields or intercropped, as part of the three sisters or mixed cropping agricultural technique.
