Helenium chihuahuense is a branching annual herb up to 78 cm (31.2 inches) tall with thick rootstocks producing only one stem with a single flower head. The leaves are long, narrow and irregularly lobed. The head is spherical or egg-shaped, with many disc flowers, each yellow with purple tips. These are surrounded by about 14-15 yellow ray flowers.[1]
