The bees here seem to be hunting for pollen on the middle male section of the spadix of this calla lily, but female pistillate flowers in the lower portion of the spadix may still be receptive, meaning that the male staminate flowers in the middle portion are not yet producing pollen. (Simple, right?) This prevents the calla lily, and all aroids, from self-pollinating. #aroids #callalily #honeybees #thehorticult
