Palmer amaranth shrub

By Bob Hartzler and Mike Owen, Department of Agronomy


Numerous weedy species in the pigweed family (Amaranthaceae) are found across Iowa, including waterhemp, redroot pigweed, smooth pigweed, Powell amaranth and others. At this time, Palmer amaranth has not been confirmed in the state, but because of its presence in surrounding states we suspect it may be here, or will appear in the near future (see April 24 ICM article).
