Butterfly Bush, sometimes called Black Knight, is a perennial plant which grows in a shape and form similar to a shrub, around 1.2 to 2 metres in height. It produces aromatic multi-coloured flowers that collectively make magnificent forms that resemble spikes. Butterfly Bush has a relatively long flowering period which spans from July to October. This exceptional variety is highly recommended for large perennial beds, lawns, or for a cut flower.
