The vibrant, hairlike strands of the pistil used to collect pollen from males. The stigmas of the pistil begin with a white coloration and progressively become yellow, orange, red, and brown throughout the plant’s maturation. They play a critical role in reproduction by providing a passageway for the genetic material to pass from a pollen grain that has landed on a stigma, to grow and fertilize the ovule, which contains the reproductive cells.
