Macoun's buttercup is a delicate native wildflower suited to moist, boggy, or riparian garden settings across western and northern North America. It thrives in partial shade with consistently wet soil, making it ideal for rain gardens, pond margins, or naturalized wet meadows. Handle with care, as like most Ranunculus species it contains irritating sap that can cause skin and digestive irritation.
