According to the Athens Science Observer, sunflowers are "a hyperaccumulator of dangerous heavy metals," which means they can draw out metal toxins from the soil and clear up environmental contamination.

Other potential applications include phytomining - growing hyperaccumulator plants on nutrient-poor but metal-rich soils to extract the elements they take up.

The tree's unusual affinity for nickel first came to light in the 1970s, and research into other hyperaccumulator plants has increased since then.
