This wetland plant gets its name because it has a powdery yellow bloom that causes water to bead. The roots of this plant can be dried and ground into a flower that is said to be delicious. The seeds can also be dried and eaten like beans. However, eating this plant raw can be poisonous. Boiling the plant does not take this away, only drying.
Scientists suggest that the plant is water repellent to wash off disease-causing fungi.
