  • Question

    This sprung up at my bird feeder and I never seen it before. Dont know if its from birdseed or what. The panicles seem to be the male portion with green pods at their base. Just out of curiousity I'd like to know what it is. Thanks!

    Answer

    Dear majikman1, the plant you have photographed is Ambrosia trifida (giant ragweed). It is a common species of cultivated fields and agricultural areas and does sometime become a "contaminant" in bird seed. Best wishes.
