SUNFLOWERS

Sunflowers are known as hyper-accumulators

Like many other hyperaccumulating plants, sunflowers remove metal compounds from deep in the soil and transport them into the stem, leaves and, flower head.

They can take up high concentration of toxic materials and are adept at extracting radioactive metals from a particular place in a period of 3-4years.

Hyperaccumulating plants are used to clear up waste during a process called phytoremediation.

P.S-A hyper-accumulator is a plant capable of growing in soil or water with high concentrations of metals, absorbing these metals through their roots, and concentrating extremely high levels of metals in their tissues.
