Red-root Amaranth
Amaranthus retroflexus
Atriplex/Chenopodium family (Amaranthaceae)

This is a common weedy plant of gardens and open ground through much of North America. The tiny green flowers are densely packed in heads. This was apparently a favorite with some Native American tribes. Seeds were parched and eaten whole or ground into flour. The plant is most well known as a spinach-like with a mild and pleasant taste. There are a number of similar Amaranthus species.
