Antennaria argentea grows in dry coniferous forests. This is a perennial herb forming a basal patch of woolly grayish oval-shaped leaves a few centimeters long and many slender erect stems up to 40 centimeters tall. It is dioecious, with male and female plants producing different types of flowers. Both flower types are clustered in many flower heads with whitish phyllaries. The female plants produce fruits which are achenes with a soft pappus a few millimeters long.[4]
