Verbascum densiflorum R. W. Smith

Old fields and roadsides; first collected in 1945 in Barry Co.

Very similar to V. phlomoides in its large flowers and tendency to a much-branched candelabrum-like inflorescence on robust plants, but with strongly decurrent leaf bases, prolonged acuminate or caudate tips on the lower bracts of the inflorescence and the upper cauline leaves, and distinctly crenate leaf margins. Both this species and V. phlomoides are handsome tall plants in the garden, with a long blooming season. Apparent intermediates with V. thapsus, presumably the hybrid V. ×humnickii Franch., have been collected in Calhoun and Lenawee Cos.
