"Google" a photo to be sure, but around here red root pigweed is wild
amaranth. The leaves are edible like spinach and in the fall the grain is
very healthy. I always leave one or two in the garden.

Yes, it is edible, even fairly tasty when young and tender. However,
like rhubarb leaves pigweed has oxalate crystals and I don't want much
oxalate in my diet. Also, this pigweed accumulates nitrates, which I
also don't want to eat much of, and in light of the fact I am adding
so much manure to the soil the available nitrates are likely to be high.

Purslane is edible too, and tastier than pigweed. So are the mustards.
