Description
Caryopteris × clandonensis is a compact, summer‑green dwarf shrub that produces dense clusters of bright blue, slightly ruffled flowers from August to October—a late nectar source when most other shrubs have faded. Its grey‑green, aromatic foliage and rounded growth make it an elegant companion in rock and dry gardens. Butterflies and bees are attracted to it.
Care instructions
Plant in well‑drained, low‑fertility soil in full sun; wet, heavy soil in winter is its greatest danger. Watering is rarely needed after establishment. Prune heavily each spring in March, cutting back to about 15–20 cm, as it blooms on the fresh growth of the current year and this keeps it dense and floriferous. In harsh conditions, a mulch layer over the root zone protects it in winter.
