Slender Sunflower blooms throughout summer, brightening the typically dry landscape of this time with its showy yellow flowers. It is similar in appearance to Common Sunflower, but smaller and less full.

The flowers are solitary on long stems, up to 3 inches in diameter with yellow ray flowers and in the center, yellow to red-purple disk flowers. The flowers can be found in bloom from May to October. Leaves are lance-shaped, rough and hairy, and 1 to 5 inches long. The plant has an erect and shrubby appearance.

The genus name Helianthus is from two Greek words meaning "sun" and "flower". The species name gracilentus means "slender".
