Buddleia Flower Power A distinctive hybrid buddleia or butterfly bush, Buddleja Flower Power is a fast-growing, medium-sized shrub with arching branches and long, deep green leaves. From July to September, purple buds open to spire-shaped panicles of sweetly scented tri-coloured flowers in brilliant shades of purple, pink and caramel-orange, which later fade to bronze; these are wonderfully attractive to butterflies, which can cover the bush in summer. Buddleia Flower Power is an easy, low-maintenance shrub; simply prune back last year’s growth to 3-4 buds in March.
