Rocky Knoll Farm
Caryopteris 'Dark Knight' (Bluebeard)
This excellent shrub is often hard to find and we usually only have a few at a time when available. Vibrant purple-blue blossoms are out throughout summer and adorn rich green and fantastically shaped foliage. Make sure to plant in well-draining soil.
We recommend that you prune every year to promote healthy, full growth. Excellent for beds, mass planting, hedgerows, or even urban growing. It likes full sun and is hardy to -20°F when protected from windchill. Can grow to about 3' tall and 3' wide when planted individually.
