This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: full sun or partial shade
  • Soil: fertile, well-drained soil
  • Rate of growth: average
  • Flowering period: July to October
  • Hardiness: frost hardy (will need winter protection in cold areas)

    Elegant spikes of small, tubular, foxglove-like flowers appear from July to October among lance-shaped, bright green leaves. This easy-to-grow perennial will quickly form large, leafy clumps and is perfect for adding a splash of colour to the middle of a sunny, well-drained border. If you deadhead regularly, the flowers will persist until the first frosts. The flowers of this penstemon can vary in colour (from magenta- violet with purple undertones, to soft violet-blue.

  • Garden care: Remove the faded blooms regularly to prolong flowering. Apply a dry mulch around the base of the plant to protect the roots from frost damage and cut back in spring when new shoots appear low down on the stem. Lift and divide congested clumps in spring.
