Caryopteris is a tough, easy-to-grow shrub that attracts butterflies and bees and is popular in parks and gardens throughout the UK. Shrubs are ideal for hot, sunny borders and awkward garden spots. Caryopteris 'Kew Blue' is a compact, neat, and low-maintenance plant. From late summer to autumn, the foliage is lightly aromatic and appears slightly silver, and the inky-blue flowers are a welcome sight. Height: 1m (36). Spread: 1.5m (59).
