Isocoma humilis, common names Zion goldenbush[2] or Zion jimmyweed,[3] is a rare North American plant species in the family Asteraceae. It has been found only in southern Utah in the United States. Some of the populations lie inside Zion National Park.[4][5]
Isocoma humilis is a low, branching shrub rarely more than 8 cm (3 in) tall. Herbage is covered with copious hairs. Leaves are narrow, oblong to oblanceolate, up to 50 mm (2.0 in) long, deeply lobed. Each flower head is up to 7 mm (0.28 in) wide (fairly large for the genus) and has 19-28 disc flowers but no ray flowers.[3][5]
