Dieteria canescens
Also called Hoary Aster, Hoary Tansyaster, Canescent Aster
Hoary tansy aster is a gray-hairy wildflower of western and central North America, usually an annual or short-lived perennial, found in dry open ground and prairie. It is a wild native rather than a common garden plant, so growing it means matching it to dry, sunny, well-drained conditions.
Dieteria canescens (formerly Machaeranthera canescens) is an annual plant or short lived perennial plant in the family Asteraceae, known by the common names hoary tansyaster and hoary-aster.
"Canescens" means "gray-hairy".
Dieteria canescens is native to western and central North America, from the Pacific Coast to the Western part of the Great Plains, from British Columbia south to California, Sonora, and Chihuahua, east to Saskatchewan, the Dakotas, and Oklahoma, with a few isolated populations in Iowa and Minnesota.
The Zuni people take an infusion the whole plant of subspecies canescens, variety canescens and rub it on the abdomen as an emetic.
