Seeded in muddy waters, the lotus rises above the mud and produces beautiful and fragrant flowers. The big showy bloom may be 8-12 inches (20-30 cm) in diameter. The flowers open for just three days. Then each petal falls silently into the water, one by one, over a short period. The large green seed head or pod remains on the top of the stalk for a long time, and gradually turning to dark color and ripe. The seeds grasped in the cone-shape pod with flat surface at the top. The pod then reverts to the water, where it floats face down, allowing seeds to take hold in the mud. The seeds then germinate in the following Spring and give rise to new lotus plants.
