WHY IS IT GREEN? Elephantopus scaber, like all plants, appears green due to the presence of chlorophyll. Chlorophyll is a pigment found in the chloroplasts of plant cells and is responsible for capturing sunlight and converting it into chemical energy through the process of photosynthesis. The green color arises from chlorophyll's ability to absorb light in the red and blue regions of the electromagnetic spectrum, while reflecting green light.

However, as with any plant species, its introduction to new habitats outside its native range could potentially lead to unintended ecological consequences.

FUN FACT: The common name "Elephant's Foot" is inspired by the shape and appearance of the plant's basal leaves, which resemble the foot of an elephant. This unique characteristic gives the plant its distinctive and memorable name.
