This summer while hiking on Cliff Creek Trail toward Beckwith Pass in the Gunnison National Forest, I photographed several Case’s Fitweed (corydalis caseana) plants. It was the only spot during my trip that I saw the Case’s Fitweed – and it took me a while to identify what this unique looking plant was.

Case’s Fitweed is poisonous to livestock. The alkaloids in the plant causes fits in sheep – which led to it’s common name of Fitweed. As with many plants that are toxic to livestock, people should avoid consuming Case’s Fitweed since it may be toxic to humans as well.

In 1874, the plants were named after Professor Eliphalet Lewis Case, a school teacher and plant collector.
