|Verbascum thapsus L.|
|common or woolly
mullein, flannel or velvet plant
This woolly, biennial, rosette plant forms a dense ground cover displacing slower-growing native species. The seeds are wind-dispersed. Fires are retarded in stands of this plant under normal conditions. Mullein has been partially controlled by a gall-forming insect which has reduced population size and range significantly.
The plant is found between 2,200-3,100 m on Mauna Kea, Hawai'i.
