Lotus Flowers Challenge – Rising From the Mud

The sacred lotus is an aquatic plant native to Asia, with large round leaves and pink or white flowers held above the water. Its roots grow in mud, yet its leaves and petals stay clean thanks to tiny wax-covered bumps that repel water and dirt.

The lotus is deeply symbolic. In Hinduism and Buddhism it represents purity and enlightenment, and deities are often shown seated on lotus flowers. India adopted it as its national flower. In ancient Egypt, the blue water lily, also called lotus, symbolized rebirth.

Lotus plants have surprising abilities, including warming their own flowers and producing seeds that can stay alive for centuries. Lotus roots, seeds and leaves are eaten across Asia, and the self-cleaning lotus effect has inspired new materials.
