The lotus effect refers to self-cleaning properties that are a result of ultrahydrophobicity as exhibited by the leaves of Nelumbo, the lotus flower. [1] Dirt particles are picked up by water droplets due to the micro- and nanoscopic architecture on the surface, which minimizes the droplet's adhesion to that surface.

In plants world, the lotus leaf is not the only example of natural superhydrophobic surfaces. For instance, taro (Colocasia esculenta) leaves were found to exhibit self-cleaning behavior, too. [19] They have a binary roughness built up by averagely 10 μm elliptical protrusions in diameter and nano-sized pins.
Epicuticular wax is a waxy coating which covers the outer surface of the plant cuticle in land plants. It may form a whitish film or bloom on leaves, fruits and other plant organs. Chemically, it consists of hydrophobic organic compounds, mainly straight-chain aliphatic hydrocarbons with or without a variety of substituted functional groups ...

In India, lotus root (also known as kamala kakaṛī in Hindi) is cooked as a dry curry or Sabzî. [48] Japan is one of the primary users of the rhizomes, representing about 1% of all vegetables consumed.
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless".

The Jingtang lotus root has three distinct features that differ from the common lotus root. Firstly, the lotus root grown in the pond is thin and long, while the common lotus root is thick and short. Secondly, after the lotus root harvest in winter, people do not need to plant it again. As long as there is water, the lotus leaf grows every spring.
American lotus is an emergent aquatic plant. It grows in lakes and swamps, as well as areas subject to flooding. The roots are anchored in the mud, but the leaves and flowers emerge above the water's surface. The petioles of the leaves may extend as much as 2 m (6.6 ft) and end in a round leaf blade 33–43 cm (13–17 in) in diameter. Mature ...
