Common names include blue butterfly bush, blue glory bower and butterfly bush. This is one of the few non-natives we carry that has a native range of tropical eastern Africa. We carry it since it has a light blue to violet flower-shaped like a butterfly and we love butterflies! Each flower has a darker blue lower petal. This is an evergreen shrub that can be 6-10' tall and up to 8' as wide. It can be propagated from cuttings. The plant grows easily in soils that are moist, well-drained, and have plenty of organic matter. It requires consistent watering and tolerates full sun to part shade, but performs best in part shade.
