Verbascum thapsus - Basal Rosette (Leaves) Basal Rosette (1st year plant)

"During the 1st year, this adventive or introduced biennial plant consists of a rosette of basal leaves about 1-2' across. During the 2nd year, it becomes 3-7' tall and is usually unbranched. Occasionally, one or two side stems may develop in the upper half of the plant. These stems are covered with downy white hairs. The alternate leaves are up to 12" long and 4" across, becoming progressively smaller and more narrow as they ascend the central stem. They are obovate or oblong-ovate, smooth or slightly crenate along the margins (which are sometimes wavy), and covered with fine downy hairs. The lower leaves taper gradually to a narrow winged base, while the upper leaves are partially decurrent against the stem. The dense branched hairs provide the foliage with a color that is whitish or greyish green. The central stem terminates in a dense spike of flowers about ½–2' long."
