(='Verbrig') Short spikes of soft violet-blue flowers are a wonderful contrast to the colourful foliage in late spring. Narrow dark-green leaves have a crisp golden-yellow edge, staying attractive all season long. Plants form a low, tight mat making this a beautiful edging plant, great when massed or grown in the rock garden. Tolerates heat and drought once established. Clip or mow after flowering to maintain an especially dense and compact habit. Quite likely hardy to Zone 3 or colder. Attractive to butterflies. From Blooms of Bressingham®.
