Picture a medium sized mound of lavender-blue flowers with silver-gray foliage in front of your favorite pink rose bush and you are probably seeing ‘Walker’s Low ‘ catmint.  Beloved by bees and butterflies, the loosely packed flowers are borne on arching stems with aromatic, intricately veined leaves, adding a wispy, nostalgic aura to the scene. If grown in a cool climate and it will bloom from late spring into fall if sheared after the first bloom. Although related to catnip, it is not attractive to cats or deer and has no serious pest or disease problems. No wonder it was the Perennial of the Year for 2007!
