Butterfly bushes are known for their prolific blooms and attraction of butterflies. Black Knight takes it to a higher level. An extra-heavy producer, its purple-black flowers are particularly striking in direct sun. This beauty is also one of the hardiest cultivars of this group. In fact, it has been rated by the Arnold Arboretum as the best Buddleia of all. All butterfly bushes have an exceptionally long blooming period that lasts from summer to early autumn.

Black Knight Butterfly Bush Feeding Instructions

Feed in Spring and then on an as needed basis through late Summer. We generally recommend a slow-release granular flower food, higher in the middle number: this is phospherous, which helps to promote strong root systems, strong stems and plenty of flowers. Alternatively, you may use a natural or organic, non-burning plant food. Refer to product label for application rates and instruction.

Black Knight Butterfly Bush Pruning Instructions

Spent flowers and/or stems can be deadheaded or sheared throughout the active growth period to encourage new growth and bloom. During the dormant season the bush can be cut back by up to 2/3 its size.

Black Knight Butterfly Bush Pest Instructions

This plant typically encounters very few pest or disease problems. If a pest or disease problem is identified, treat with an insecticide product, preferably one containing "Neem oil". Neem oil is a safe, triple-action product that can be used to control insects, mites and diseases. If your plant appears seriously stressed or diseased, consult with your local nurseryman, arborist, professional landscaper or local extension agent.
