Rocky Knoll Farm
Caryopteris Dark Knight
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 and 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.
