PlantSnap identifies a Curlycup Gumweed (Grindelia squarrosa)

Grindelia squarrosa, also known as a curly-top gumweed or curlycup gumweed, is a small North American biennial or short-lived perennial plant.

It is native to western and central North America, from British Columbia east to Québec and New England, and south as far as California, Arizona, Chihuahua, and Texas. The species may possibly be naturalized in much of the eastern part of that distribution.

Grindelia squarrosa is often found in disturbed roadsides, streamsides; 700–2,300 metres (2,300–7,500 ft) in elevation. It is a decumbent to erect, much-branched perennial herb of subshrub up to 100 cm (40 inches) tall. The 1.5–7 cm leaves are gray-green, crenate with each tooth having a yellow bump near its tip, and resinous.
