Fun, weird, helpful, or little known fact
This beaming buttercup emerges along the edges of snowfields immediately after the snow melts, and sports fine, thread-like leaves (compared to its cousin, R. escholtzii).  The flowers of the Alpine buttercup display heliotropism; that is, they track the sun's movement from early morning until mid-afternoon.   Flowers aligned parallel to the sun's rays reach average internal temperatures several degrees Celsius above ambient air temperature, and attract more pollinators (in this case, flies) more often as a result.
