Taenidia integerrima, the yellow pimpernel,[1] is an herbaceous plant in the parsley family.

[2] Its natural habitat is rocky prairies and woodlands, often over calcareous substrates.

[5] It is listed as endangered in Connecticut,[6] as historical in Rhode Island, and threatened in Vermont.

[7] The Menominee take an infusion of root taken for pulmonary troubles, chew the steeped root for 'bronchial affections',[8] and use it as a seasoner for other remedies because of the good smell.

[9] The Ojibwe smoke the seeds in a pipe before hunting for good luck.
