Characteristics:

Snow Buttercup is an extremely attractive buttercup, often found in dense clumps, with somewhat succulent leaves and stems. It frequently may be found blooming in areas recently uncovered by snow melt.

The leaves are mostly basal and are ternately (3-times) to palmately divided. The leaf lobes are wedge shaped, and are often 3-lobed. The stem leaves are divided into narrowly elliptical-shaped segments.

The bright yellow flowers are found singly at the tips of the stems. The five shiny yellow petals are up to 2 cm long and wide. The sepals are green. Numerous yellow stamens and numerous, tiny green pistils are found at the center of the flower.
