Nahanni Aster is a perennial wildflower. Its flowers have yellow centres and white to pale pink or purple petals. It typically grows in clumps of about two to ten stems which are green to reddish and often have fine woolly hairs towards the base. The stems are branched to form an open cluster of flowers. Nahanni Aster is similar in appearance to the Rush Aster (Symphyotrichum boreale) which also occurs in the Nahanni area.
