This willowherb has petals hardly a quarter inch long. The tube behind the petals is the ovary. The seeds will have reddish hairs that enable distribution by wind. Those hairs account for the name. The plants get around two feet tall, and provide food for some moth caterpillars and for herbivores. They have gotten little attention from humans.
