Great Mullein is an imposing plant with interesting foliage and form. The flowers seem small and inconspicuous in comparison with the rest of the plant. This is an easy plant to identify, although there are other Verbascum spp. (Mulleins) in the Old World that have a similar appearance. Of these, only Verbascum phlomoides (Orange Mullein) is known to occur in Illinois, although it is rare within the state. This latter species has larger flowers (at least 1" across) that range in color from pale yellow to orange-yellow. While Great Mullein has dense spikes of flowers, the flowering spikes of Orange Mullein are more interrupted and less dense. The leaves of Orange Mullein are less hairy and more green on the upper surface, and its upper leaves are only slightly decurrent against the stem. There are other introduced Mulleins, but they are smaller and less hairy plants that produce panicles or racemes of flowers, rather than spikes. At one time, the dried stalks of Great Mullein were dipped in wax or tallow and used as torches.
