Caryopteris 'Dark Knight', has a deeper bloom color than the popular 'Longwood Blue' with the same silver colored foliage that makes the bluemist shrub a spectacle out of bloom. Perfect for hedges, the mixed border, specimen, and mass plantings. Loved by butterflies, bees, hummingbirds, and disliked by deer. Drought tolerant once established.
