Flower:

There are a few to several flowers at the end of long, naked, loosely branching stems at the top of the plant. Flowers are 1½ to 2½ inches across, have 8 to 15 yellow petals (ray flowers) and yellow center disk flowers.

Leaves and stem:

There is a rosette of long-stemmed leaves around the base of the plant, plus 1 to a few pairs of oppositely attached small leaves widely spaced up the main stem. Basal leaves are up to 4 inches long and 1½ inch wide that are oval to triangular in shape, with a blunt or pointed tip. The stem leaves are similarly shaped, with little or no leaf stem. All leaves are toothless or nearly so and are very rough to the touch. The main stem is covered in flattened hairs and is often reddish brown.

Notes:

Few-leaf Sunflower is easy to identify by the leaves.
