Palmer's Amaranth, agricultural weed, may be in contaminated pollinator seed mixes

Palmer's amaranth, Amaranthus palmeri was recently discovered in Malheur County. Palmer's amaranth is a problematic agricultural weed in much of the southern and mid-west US. Recently the Weed Science Society of America reported that Palmer's amaranth is suspected to have contaminated seed mixes marketed as pollinator seed mixes. Given each plant can produce from 100,000 to 500,000 seeds a year, it isn't surprising these seeds could find their way into unwanted places!
