Caryopteris incana ‘Dark Blue’

We grow this species from seed because it produces such an opulent display of intense blue flowers late in the season. Whorls of flowers are absolutely irresistible to pollinators when it blooms from late July to September. A mostly herbaceous species that dies to the ground. Much more dense and compact plants than other Caryopteris which we find kind of sparse and weedy. To 2′ tall and as wide. Full sun, rich, well drained soil with regular summer water. Takes drier conditions in rich soil. Mulch in fall. Cut back dead tops in spring when you see new growth begin. Aromatic. Bee’s, you plant it for the big ol black wooly bumble bees.
