Helianthus californicus is an erect perennial herb growing from a network of tough, woody roots with small rhizomes. It is a sprawling, gangly plant, sending a thin stem to heights between one and three meters (3-10 feet) or more. The lance-shaped leaves may be 20 centimeters (8 inches) long and are smooth or slightly toothed along the edges. The inflorescence holds several flower heads. Each head is supported by a base covered in long, pointed phyllaries that bend back as the head ages and develops fruit. The flower head has a fringe of golden yellow ray florets, each two or three centimeters (0.8-1.2 inches) long, and a center filled with curly yellow and brown disc florets. The achene is about half a centimeter (1.25 inches) long.
