About Common Woolly Sunflower (Eriophyllum lanatum) The Common Wooly Sunflower (Eriophyllum lanatum), also known as Oregon Sunshine, is a widespread, herbaceous dicot of the sunflower family Asteraceae. It is native to western North America, commonly growing in dry, open places below 10,000 feet, but it also grows on rocky slopes and bluffs. It is most common in California, primarily in the mountains of the northern part of the state where it is widespread. This perennial plant grows from 1 to 2 feet (30 to 60 centimeters) in height. Flowers are yellow and composite, looking much like true sunflowers, and sometimes grow to 2 inches wide. Both the ray and disk flowers are yellow, with one flower head on each flowering stalk. The leaves are linear on the upper stems; the lower portions of the stem have slender, pinnately lobed leaves. The species exhibits great variability. There are many recognized varieties, and some are classified as rare.
