Definition
A buttercup is a bright yellow flower, often seen in meadows and fields. Its petals have a characteristic glossy sheen. The flower's name comes from the belief that the yellow color of butter was due to cows eating buttercups. Buttercups are typically small, cheerful flowers that bring a pop of color to grassy landscapes. They are a symbol of charm and simplicity. However, don't be fooled by their cuteness; buttercups contain a toxin called ranunculin, which can cause skin irritation.
