Pigweed grows in annoying abundance in my flower beds and garden every June and July. It's easy to pull up, but there is so much of it. I've never eaten any, but Old Pigweed tempts me to try. The species with the red flower head that grows upright, then droops from its own weight is a cultivated flower with the old fashioned name of "Love Lies Bleeding." There is also a variety with beautiful wine colored leaves and stems.
