Grindelia grandiflora, the manyray gumweed,[3] is a North American species of flowering plants in the family Asteraceae. It is native to the south-central United States and north-central Mexico, in the states of Texas and Coahuila.[4][5]
Grindelia grandiflora grows in grasslands, scrublands, ditches, and roadsides, and along streambanks. It is an annual herb sometimes as much as 200 cm (80 inches or almost 7 feet) tall. The plant usually produces numerous flower heads in open, branching arrays. Each head has 17-26 ray flowers, surrounding a large number of tiny disc flowers.[6][7]
