Celery-leaved Buttercup, also known as Cursed Buttercup (Ranunculus Sceleratus) is an annual or short-lived perennial forb in the Buttercup Family (Ranunculaceae). It’s native to North America and Eurasia, blooms Jun-Aug and grows 1-2 ft. It’s commonly found in wetlands, swamps, around ponds, wet meadows and streams in forests. Tolerates standing water to moist soils and partial to full sun exposure.
Celery-leaved Buttercup is the most toxic buttercup due to a 2.5% concentration of protoanemonin; which causes sores and blisters on human skin when leaves are crushed.
