The Black Knight butterfly bush displays a riveting summer color. It also has a light delightful fragrance and its dark violet-purple flower spikes are outrageously striking. It is a fast growing shrub that works well as a foundation shrub it can also be used as an accent plant or as a background in borders. It is slightly hardier than other varieties, it may wither during cold winters but will emerge vigorously once again in spring.
