This biennial or short-lived, semi-evergreen perennial forms rosettes of leaves densely covered with grayish-yellow hairs. In summer, its bright-yellow or occasionally white blossoms flower along erect, branching stalks up to 5 feet high. It has naturalized in regions of the U.S.

This is one of the few truly perennial species of mullein. Pale yellow blossoms with purple filaments bloom profusely on long flower stalks in mid- and late summer, reaching about 3 feet high. Individual flowers are short-lived but numerous, and flowering takes place over a long time. Verbascum chaixii's glossy, dark green rosettes are semi-evergreen. 

Long-lasting, terminal clusters of lime green bracts and flowers punctuate the meandering 'arms' of this ground-hugging species. The chalky seafoam foliage looks great spilling over a stone wall in a rock garden or at the edge of any bed.

This choice species makes a strong vertical statement with its large, smooth, sea-green leaves and towering stems to 6 feet tall. It bears short, yellow ray florets with giant, upright cones at the center. It prefers average soil with good drainage, and is excellent in native or wild plantings.
