Description

Seven-son flower is a rare, ornamental shrub or small tree native to southeastern China and now extinct in the wild. It produces fragrant, creamy-white flowers in late summer, followed by persistent, rose-colored calyces and small purple-red fruits in fall, extending ornamental interest well into the colder months. Though rare in the wild, it is becoming increasingly available in horticulture and is valued for its resilience and multi-season appeal.

Hardy in USDA Zones 5–9, Heptacodium miconioides prefers full sun and well-drained soils, adapting well to urban environments and tolerating moderate drought once established. The genus name means “seven bells,” referencing the number of flowers arranged in each whorled cluster. As a monotypic genus and relict species, Heptacodium holds unique phylogenetic interest. Its late bloom provides vital forage for bees and butterflies, while the colorful calyces and fruits enhance its ecological and aesthetic contributions in fall gardens.
