An article I read in the Smithsonian Magazine stated that: “Flowers sway in the breeze to beckon pollinators, a study from Wales’ Aberystwyth Univeristy suggests. Sea campion plants with slim stems flutter the most and attracted the most insects. (Flowers with average stens set the most seeds though, apparently because pollinators visited more stable flowers longer.) The study is the first evidence that “waviness,” like color and scent, influences a flower’s attractiveness.
