Caryopteris × clandonensis 'Heavenly Blue'
bluebeard
Clusters of piercing, slightly fluffy, dark blue flowers appear in August and 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.
Caryopteris × clandonensis 'Heavenly Blue' 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.

How to care for Caryopteris × clandonensis Heavenly Blue:
Plant Caryopteris in a sunny, well-drained spot—it's not tolerant of wet or heavy soils, especially in winter. Improve drainage before planting if needed by adding grit or organic matter. These small, deciduous shrubs prefer a sheltered site and do best against a warm wall or in a border that gets plenty of sun.
Once established, they’re drought-tolerant and low maintenance. In early spring, cut back all flowered stems hard to a low, woody framework to encourage strong new growth. After pruning, apply a 2-3in (5-7cm) mulch of well-rotted compost to help retain moisture and boost soil nutrients.
