The dark purple-violet flowers of the Black Knight Butterfly Bush Tree make this tree-form buddleia a knockout specimen. Growing to around 6 to 8 feet tall, the Buddleja davidii 'Black Knight' grows quickly and blooms from mid-summer until the fall. Gray-green foliage provides the perfect base to set off the canopy’s flowering spikes.
The Black Knight Butterfly Bush Tree is ideal for most locations, as it is easy to care for and both deer and rabbit resistant. A deciduous shrub, it is considered cold hardy in zones 5 to 9 and may die back in a harsh winter only to reemerge with vigorous new growth in spring. Black Knight is an ideal shrub for the back of a border or a wildlife area due to its appeal to butterflies.
Black Knight Butterfly Bush Tree Care
The Black Knight Butterfly Bush Tree performs best in full sun but can also tolerate partial shade. Water regularly for the first growing season, after which it can cope with dry spells. Plant in well-drained soil and avoid sites prone to waterlogging. The Black Knight Butterfly Bush Tree rarely requires any fertilization.
Deadheading the spent blooms will encourage reblooming into the fall. Prune to shape and size in late winter or early spring, cutting back growth to a pair of healthy new buds.
Black Knight Butterfly Bush Tree Spacing
The Black Knight Butterfly Bush Tree can reach a mature size of 6 to 8 feet tall and 3 to 5 feet wide. Multiple shrubs can be planted around 4 to 5 feet apart for a well-defined canopy.

Plant Addicts Warranty - 1 Year (Extra Purchase Required)
We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die. Hungry animals, drought, poor soil conditions, over watering, diseases & pests are all good examples of what can cause plants to die. The Plant Addicts Warranty is a 1 year warranty protecting you from all of the unknowns and will replace your plant if something were to happen to it.
The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability). We may ask for photos for documentation purposes, but we try to make the process as easy as possible.

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
