Buttercup wildflower

The wild buttercup is a kind of flower. It has yellow, glossy petals, and grows wild in lots of different places. It thrives best in moist sites. The distinctive, shiny, waxy texture of Buttercup petals is caused by a special layer of cells just beneath the surface cells. As the species name implies, the juice from stems and leaves is acrid, discouraging browsing animals, and favoring the spread of the plant.
