Whiteman's Foot is a term that refers to the invasive plant species named "celandine poppies." This plant has yellow flowers and long-stemmed leaves that resemble those of a poppy. However, it is categorized by invasive species because of its tendency to spread aggressively and suppress native plant species. Some synonyms for Whiteman's Foot include "celandine poppy," "yellow poppy," and "greater celandine." The plant originated from Europe and Asia and was initially used for medicinal purposes. However, its introduction in other parts of the world has resulted in a significant environmental problem that requires urgent attention.
