Tall buttercup (Ranunculus acris) is a perennial forb that is native to central and northeastern Europe. It's found throughout the United States, particularly in damp meadows, grasslands and overgrazed pastures. R. acris flowers in late spring, with peak growth during the early summer months.
Toxic components
All parts of R. acris contains ranunculin, a type of glycoside that is able to convert into protoanemonin, which is toxic to ruminants.
