Wild Geranium

Another name for this flower is Cranesbill, which refers to the seed case that develops and protrudes from the center of the flower. It does look rather like a Crane's bill. It is another one of those flowers that catapult their seeds. The seed case drys becoming like a tightly wound watch.... the spring holding a lot of energy. When the conditions are right all five sides of the seed case spring, curling backwards ... at the same time hurling the seeds upward and outward. This is not the only surprising trait this plant has..... the seeds are able to crawl ! The seeds have a tail which when it is dry the tail curls, and when the conditions are wet it uncurls. This motion causes the seed to move about until it becomes blocked by another plant or twig .... and then it is believed that this crawling motion pushes it into the soil where it can eventually germinate.
