Heptacodium miconioides is a large, fountain-shaped, multi-stemmed, deciduous shrub that typically grows to about 6 meters at maturity with a 3-meter spread. Irs smaller size makes it an excellent tree for a smaller property. It produces panicles of fragrant, creamy-white flowers in late summer to early fall. Flowers appear in flattened clusters of stalkless blooms within typically seven-branched clusters, hence the common name Seven Sons. Flowers are followed in fall by an equally showy (if not showier) display of small, purplish-red fruits (drupes) crowned by very showy, rose-pink calyces which elongate after bloom and last into late fall. Tan bark exfoliates to reveal attractive brown inner bark, which provides good winter interest. This plant, native to China, is now rare there and its wild populations are vulnerable to extinction. However, it has become better known in North America and more gardeners are enjoying its spectacular fall display. It is a good source of nectar for butterflies and other insect pollinators in the fall. The specimen is our garden has been thriving in part shade for at least fifteen years.

Growing and Maintenance Tips
This beautiful and unusual plant is very easy care. It isn't finicky about soils, though it does appreciate regular moisture and good drainage. It will not require any special pruning, though you may prune or train it to your liking if you prefer. Prune in late winter or early spring, as the flower buds begin to set shortly after the plant leafs out. It does not need special fertilizing, but if you wish to encourage more rapid growth, you may apply a granular fertilizer formulated for woody plants (like a rose fertilizer) in early spring or top dress with compost.
