"Downward dropping petals known as falls dangle beneath the standards. Falls petals function as a landing pad for pollinating insects. These petals feature markings that help direct insects toward the flower’s reproductive parts. On bearded iris, the beards—a series of hairs arranged in a line—act as a gripping agent, giving pollinators a surface to grab and hang onto as they ascend the falls petals toward the flower’s center."
