Curlycup gumweed

Description:

from Native Plants Database of the Lady Bird Johnson Wildflower Center: "Stout erect stem bears several branches with yellow daisy-like flower heads. This tough but short-lived perennial, a common invader of overgrazed rangeland in the West, has now spread to dry waste places in the East. Because of its bitter taste it is not eaten by cattle."

Habitat:

from Native Plants Database of the Lady Bird Johnson Wildflower Center: "Native Distribution: Native in western and southwestern North America, ...Native Habitat: Prairies and waste places."

Notes:

Growing sandy/gravelly poor soil in my native shortgrass prairie yard in Estes Park. Buds and flowers have a sticky substance, therefore the 'gumweed' name.
