A garden classic since 1959, ‘Black Knight’ butterfly bush boasts some of the most dramatically colored flowers you’ll find in a butterfly bush. They aren’t quite black, but they are an intriguing deep purple-blue that few other plants can match. This butterfly bush looks fantastic paired with bright pinks, crisp whites, and cheery yellows. Deadheading is recommended for this old-fashioned variety to encourage continued flower production.

‘Black Knight’ received the prestigious Award of Garden Merit from the Royal Horticultural Society (RHS) in 1993. Cannot be shipped to OR or WA.

FAQs

Care & Planting Guide

After your plants have arrived:

The plants in this box have just spent a lot of time being jostled around in the dark and must be unboxed right away. Unpack the entire box, removing packaging material and plants. Remove any plastic covering the pot and/or soil surface and check if the soil is dry. Water anything that is dry or looks wilted. Any plants that have come unpotted during shipping can be replaced in their pots and their roots covered with soil.

Place plants in a cool, shaded spot out of direct sunlight for 24- 48 hours after unpacking them. This allows them a recovery and acclimation period before planting. If you must hold them longer, place them out of direct sunlight, wind, heat, and cold. Check daily for watering.

USDA Hardiness Zones

USDA Hardiness Zones Map

ZONE HARDINESS

The United States Department of Agriculture (USDA) has devised a system to provide gardeners with a basic guide to plant hardiness – how much winter cold a plant can withstand. The Hardiness Zone Map system divides the United States and Canada into numbered zones based on lowest average winter temperature. Even within a zone, different micro-climates exist, such as large urban areas which may be warmer or land situated at different elevations.

WHAT EFFECTS PLANT HARDINESS

The Hardiness Zone Map is a valuable tool but it is not foolproof. There are a variety of factors that can influence the hardiness of a given plant in a garden. These factors include: soil type, drainage, snow cover, exposure to wind, winter, rainfall (or lack of), as well as fluctuations in temperature.

dead

The Black Night was completely dry and dead from lack of water, in addition some of the branches were broken, however, Butterfly Bushes has promised to send a new one when the weather is cooler, my recommendation is to ship live plants overnight or 2 day to prevent this from happening

We apologize that you received plants that are not up to our standards. While we try our best to provide exceptional service, some factors, like shipping and handling, are outside our control, and issues like this can sometimes happen. We are glad to hear that our customer service team was able to help.
