Winter hardy to USDA Zones 9-11 where it is grown in moist, organically rich, well-drained soils in full sun to part shade. In St. Louis, it is best grown in containers where it can be typically maintained as a small rounded shrub. Containers can be overwintered in bright sunny conservatory-like rooms or greenhouses, but in the absence of these facilities, plants are best forced into dormancy and stored in a cool, dark, dry location until spring.

Noteworthy Characteristics

Native to tropical Africa, blue glory bower is a sprawling evergreen shrub with a weak upright habit. It grows to 6-10’ tall in its native habitat, but more typically grows 2-4’ tall in containers in the St. Louis area. It is sometimes commonly called butterfly bush (though totally unrelated to Buddleja) because its bicolored light blue/violet flowers with long protruding purple stamens purportedly resemble butterflies in flight. Blooms in late summer to fall. Elliptic to narrow obovate glossy dark green leaves (to 4” long).


No serious insect or disease problems. Watch for aphids and whitefly.
