Marsh marigold

Caltha palustris, commonly known as marsh marigold or kingcup, is a perennial wildflower native to temperate regions of the Northern Hemisphere. It is easily recognized by its glossy, heart-shaped leaves and bright yellow, buttercup-like flowers that bloom in early spring. The name “marigold” derives from “Mary’s gold,” a reference to its traditional association with the Virgin Mary in medieval Europe. Unlike many early bloomers, Caltha palustris thrives in wet environments such as marshes, stream edges, and wet meadows, where its vivid flowers signal the return of spring and provide early nourishment for pollinators.
