It is native to northern Alaska, much of Canada including the Arctic territories, and the northern United States as far south as northern California, Colorado and North Carolina.[4] Antennaria howellii is an evergreen perennial plant. The form is usually basal rosettes, largely clonally propagated. The basal rosette leaves are 2?4 cm long and 6?12 mm broad, light green and spatulate, with a thin arm and a broad tip with a point.
