About Silver Pussytoes (Antennaria argentea) Antennaria argentea is a North American species of flowering plants in the daisy family known by the common name silver pussytoes or silvery everlasting. It is native primarily to Oregon and to northern and central California with additional populations in Nevada, Idaho, Montana, and Washington. 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.
