Caltha palustris
Caltha palustris, commonly known as marsh marigold, is a native bog plant found in temperate regions of the Northern Hemisphere. It thrives in marshes and wet woodlands, producing bright yellow flowers from April to August. This perennial herbaceous plant can grow up to 18 inches tall and wide, with round, textured green leaves. While its raw form is toxic, it becomes edible when cooked. Marsh marigold is often confused with invasive species but is a valuable addition to bog gardens and wetland areas.
