Bur Buttercup-Ceratocephala testiculata

This pretty little yellow flower is in the Buttercup Family (Ranunculaceae--from Latin for frog)--also called the crowfoot family because of the divided leaves. The pretty flower transforms into a sticky bur, thus the common name, bur buttercup (Ceratocephala testiculata). 

It's a tiny plant, usually growing no more than a few inches high, in close proximity to other bur buttercups. It often grows along roadsides and waste areas, but I also found quite a few growing under pinyon pines and Utah junipers.

This annual flower is native to southeastern Europe. It contains a compound that is poisonous to sheep.

Bur buttercup is one of the earliest bloomers, usually showing its color when temperatures reach 45-50 degrees. Although the plant is small on the surface, its root more than doubles the length of the plant. For more information about bur buttercup, click here.
