This year at the Iowa State University FEEL weed garden I've established a plot with nine weedy members of the Amaranthaceae family, including six pigweeds . The pigweeds were transplanted on June 9 and pictures taken on June 11. Species include redroot pigweed, tumble pigweed, Palmer amaranth, spiny amaranth, Powell's amaranth, and waterhemp. How many can you correctly identify?
