Eriophyllum Lanatum, Woolly Sunflower

Plants > Wildflowers > Asteraceae > Eriophyllum Lanatum

The yellow, sunflower-like blooms of eriophyllum lanatum are about 2 inches in diameter and consist of 8 to 12 ray florets (usually 8) and many tiny disc florets, which when mature form a semi-sphere at the plant center. Flowers grow singly on stems that may be branched or unbranched and have a few small, ovate, undivided leaves at intervals; most leaves grow at the base of the stems and are pinnately divided. Leaves and stems are covered by fine, woolly hairs. This common plant is widespread across the Pacific and northern Rocky Mountain states, and has 12 recognized varieties.
