Caryopteris x clandonensis Heavenly Blue



Light blue flowers produced late in the season

A reliable older variety of Bluebeard which is still worth its place in any garden. This plant will reward for weeks in late summer with flat clusters of rich blue flowers that are a magnet to butterflies and bees.


Happiest grown at the front of a border in full sun and well drained soil.


Add grit to the planting hole if your soil is heavy and gets wet in winter. Cut back to tidy the ends of the twiggy branches in late spring once the new leaves are seen.

The silvery grey leaves of Caryopteris are pleasantly aromatic.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.

Planting site Gravel garden, Flower border and beds, Banks and slopes, Cottage garden, Informal garden, Coastal or drought resistant
