Dark Knight Blue Mist spirea (Caryopteris clandonensis) blooms with a profusion of dark blue flowers in late summer when few other shrubs are flowering. Its modest size makes it very useful in smaller yards. A fantastic nectar source for bees and butterflies. Drought resistant/drought tolerant plant (xeric).
