Botanical Name:

Caryopteris has blue flowers that bloom late in the season on silver green foliage. It should be treated as an herbaceous perennial and cut to the ground in winter, and a light pruning after the first bloom will often stimulate another flush.

Caryopteris ‘Dark Knight’ is a small shrub with attractive, narrow, grey-green foliage and during the late summer months masses of pretty dark blue flowers. It’s a tough shrub, capable of taking dry conditions in its stride once established.
