Bluebeard

Caryopteris x clandonensis Heavenly Blue

• Position: full sun
• Soil: moderately fertile, light, well-drained soil
• Rate of growth: average
• Flowering period: August and September
• Hardiness: fully hardy
  
  Clusters of piercing, slightly fluffy, dark blue flowers appear in Augustand September at intervals on long stems among pointed, aromatic, grey-green leaves. With its strongly upright habit, this lovely, dark blue form of 'bluebeard' is perfect for the middle of a sunny shrub or mixed border.  It is also a magnet for bees and butterflies and is drought-tolerant. Where temperatures fall below -15°C it's best grown against a warm, south or west-facing wall.
  
  
• Garden care: In March prune all of the flowered stems back hard to the permanent framework. After pruning apply a generous 5-7cm (2-3in) mulch of well-rotted garden compost around the base of the plant.
