Botanical Name: Verbascum densiflorum Common Name: Dense-flowered mullein, Large-flowered mullein Synonyms: V. thapsiforme Genus: Verbascum
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.
 Noteworthy characteristics: Plants are well-adapted to cottage, gravel, and rock gardens or naturalized areas. Erect stems bearing profuse saucer-shaped flowers are usually yellow, but also white, brownish-red, or purple. Individual flowers are short lived but numerous, and flowering takes place over a long time. This species will self-sow, but not as a nuisance, and many seedlings vary slightly from the parent cultivar, thus creating welcome surprises.
 Care: Provide any well-drained soil in full sun or part shade.
