Time and Color:
Dark purple flowers summer through fall.
Perennial. The Black Knight butterfly bush variety is
nectar source to attract butterflies with. It is the darkest flowered
of all the buddleias, almost a grape-violet, and always one of the most
popular. This plant is awesome in front of gold foliaged plants. The
smaller foliage and shorter stature give Black Knight the effect of
being more graceful and airy. Grows 15ft by 10ft.
Keep cut faded flowers cut off bush regularly to keep
throughout the summer. This plant blooms on new growth and should be
pruned back to the ground in spring.
