Upright Prairie Coneflower
Ratibida columnifera
Aster family (Asteraceae)

A tall finger-like column with a bottom fringe of yellow petals identifies the Prairie Coneflower at a distance. The yellow petals can also have rich red-brown tones. Its appearance lends it a rich assortment of names including "Thimbleflower" and "Mexican Hat."
