Buttercups are a bright yellow flower with five petals. The flowers usually grow at the top of a long stem. The leaf shape depends on the species, but they usually have wavy edges that zig and zag deeply back and forth.
There are nearly a hundred species of Buttercups growing in the United States, and four hundred species world-wide. All Buttercups are poisonous when eaten fresh by cattle, horses, and other livestock, but their acrid taste and the blistering of the mouth caused by their poison means they are usually left uneaten.
