Arctic Summer Mullein
Arctic Summer mullein is a striking flowering plant. Since it is a biennial, it lives only for two years. The first growing season, the large, woolly silver leaves form a basal rosette.
The following growing season, a sturdy stem rises from the center and holds one or more flower stalks bearing round, yellow flowers. After flowering, the plant dies. Seedlings may grow and replace the original plant if the seed is allowed to mature and disperse.
This is a different plant than the weedy common mullein found throughout Colorado.
