Summary:

Verbascum thapsus was introduced to the island of Hawaii around 1900 and has since spread into dry montane environments on the slopes of Mauna Kea, Mauna Loa, and Hualalai volcanoes. A quantitative survey of roadside mullein populations along the Saddle Road ascending the slopes of Mauna Kea and Mauna Loa resulted in determination of the morphological variation along steep topo-climatic gradients. Over the elevational range of mullein on Mauna Kea, the species exhibits striking variation in gross morphology and life history, showing mean rosette diameter, plant height, and woodiness increase with elevation.
