Caryopteris × clandonensis ‘Grand Bleu’ (also known as ‘Grand Bless’) is a compact, deciduous shrub celebrated for its vibrant blue flowers and aromatic foliage. Growing to a height of 60-90 cm, this plant features clusters of deep blue flowers that bloom from late summer to early autumn. For optimal growth, plant Caryopteris ‘Grand Bleu’ in well-drained soil in a sunny position, making it perfect for borders, containers, or as a low hedge.

Flowering from August to October, Caryopteris ‘Grand Bleu’ offers a stunning display of color when many other plants have finished blooming. Pruning should be done in early spring—cut back the previous year’s growth to a low framework to encourage vigorous new shoots and maintain a compact shape.

Feeding Caryopteris ‘Grand Bleu’ is straightforward. Apply a balanced, slow-release fertilizer in spring to support healthy growth and abundant flowering. Additionally, mulching with organic matter can help retain moisture and improve soil fertility.

Caryopteris ‘Grand Bleu’ is particularly beneficial for bees and other pollinators. Its late-season flowers are rich in nectar, providing an essential food source when other nectar-rich plants are scarce. By adding Caryopteris ‘Grand Bleu’ to your garden, you not only enhance its visual appeal but also support local pollinator populations, contributing to the overall health of your ecosystem. This easy-care, drought-tolerant shrub is perfect for adding both beauty and ecological value to your outdoor space.
