Grindelia howellii, or Howell's gumweed,[1] is a North American species of flowering plants in the family Asteraceae. It is native to the northwestern United States, in the States of Idaho and Montana.[2]
Grindelia howellii grows in open, sunny sites on rocky slopes and in alluvial deposits. It is a perennial herb sometimes as much as 150 cm (5 feet) tall. The plant usually produces numerous flower heads in crowded, flat-topped arrays. Each head has 18-25 ray flowers, surrounding a large number of tiny disc flowers.[2][3][4]
