"The Butterfly Bush 'Royal Red', Buddleia 'Royal Red', is not quite a true red color, but purple-red flowers are borne on this beautiful upright growing shrub. It is a vigorous growing shrub that boasts purple -red flowers from mid-summer and is a butterfly magnet. This bush flowers summer and fall and is easy to grow. Plant it near a path or patio and the shrub will provide a delightful fragrance for you, too. It's generally pest-free. This plant blooms on new growth and should be pruned back to the ground in spring."
