Erodium cicutarium “Stork’s Bill” Geraniaceae
April 23, 2015
Erodium is famous for its fascinating dispersal mechanism. Their fruits are shaped like a stork’s bill (hence the common name) and separate into five seeds with a wirey tip upon maturity. As the seeds dry out, they begin to curl up into a corkscrew-like shape. If they are resting on soil as they begin to dry, this curling process will drive them into the ground. You can watch this self-planting mechanism here or check out the GIF below. It’s really freaking awesome!
