Cooks and gardeners alike are indebted to this evergreen perennial for the unique, pungent flavor and aroma that its gray-green leaves produce. This charming cultivar has green leaves with irregular yellow margins. It forms a 1.5- to 2-foot-tall and 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 occasionally sends up lavender-purple flower spikes; it has both ornamental and culinary qualities in an herb garden. It tolerates alkaline soils, but not wet winter conditions.
