  Deep violet to lilac-blue summer flowers and aromatic mid-green leaves. This violet-lilac catmint makes excellent, long-flowering, groundcover for a sunny border. Clipped back after the first flush in June, it flowers through to early autumn. Useful as an informal, scented edge for paths as, when trodden on, the foliage releases a pleasant aroma.
  
  
• Garden care: Lift and divide large clumps in spring, replanting divided specimens with lots of well-rotted organic matter. If powdery mildew becomes a problem prune out the affected areas and treat the remaining plant with fungicide.
