Isocoma pluriflora grows 1–3.5 feet (0.30–1.07 m) tall. Leaves are narrow, up to 5 cm (2 inches) long. The plant produces numerous flower heads in a cluster at the top of the stem, each head with 8-21 yellow disc flowers but no ray flowers. The species is named "pluriflora", 'many flowered', for its up to 25-50 vertical and approximately parallel stalks, tipped with yellow golden flower heads.[5]
