Butterfly Bush ‘Black Knight’ flowers are a rich deep purple and very fragrant! It will bloom from early summer into fall, attracting butterflies like no other bush can!

On its own it can grow 6-8 feet tall and 3-5 feet wide, but pruning it to within 1 or 2 feet of the ground in the early spring will control the height and keep it from getting too woody.

It will do best in full sun. Plus, it is adaptable to a wide range of soil types.
