It grows mainly in coastal habitat and that of the hills and mountains overlooking the coastline. This is a generally erect but sometimes spreading or prostrate plant with stems up to half a meter in length. It is green to gray to red in color and usually hairy in texture. The leaves are located at the base of the plant; there are also bracts along the stem at the bases of the inflorescences which look like leaves. The inflorescence is a dense cluster of flowers, each flower surrounded by six white to pink hairy bracts tipped in hooked awns. The flower itself is only a few millimeters wide with jagged tepals.
