Verbascum phoeniceum (Purple mullein, Mullein)

Cooks and gardeners alike are indebted to this evergreen perennial for the unique, pungent flavor and aroma that its gray-green leaves produce. S. 'Berggarten' is more compact than the species, forming a 2-foot tall by 3-foot wide bush with woody stems that may be trimmed back to newly emerging growth or strong stems in spring. In early to mid-summer, it sends up purple flower spikes. It boasts attractively rounded leaves and, like the species, has both ornamental and culinary qualities in an herb garden. It tolerates alkaline soils, but not wet winter conditions.

This woody-stemmed perennial produces sticky spikes of deep violet or, rarely, white to pink flowers. It blooms from early summer to autumn; reblooming is most reliable if spent flowers are deadheaded promptly. It has wrinkled leaves and forms an upright clump 3 feet tall by 1 foot wide. This salvia is most noted for its many hybirds with S. nemerosa.
