Heptacodium miconioides or commonly referred to as seven son flower is a wonderful deciduous shrub with distinct three veined leaves that are retained into early winter. The small, white, fragrant flowers are followed by showy bright red calyx in fall. When you include the unusual peeling bark you have a plant that is appealing in all four seasons.

This is essentially a large, fountain-shaped, multi-stemmed, deciduous shrub that typically grows 15 to 20 feet at maturity with a 10 foot spread (select your site for this plant carefully). You can also shape this plant into a single-trunk tree. Terminal clusters of fragrant, creamy-white flowers begin to appear in late summer and continue to early fall. Within each whorl are 7 tiny flowers (hence the common name of seven son flower). Flowers are followed in fall by an equally showy (if not showier) display: small, purplish-red fruits (1/2 inch long drupes) crowned by five very showy, sepal-like rose calyces which elongate after bloom and last into late fall.  You will come to really appreciate the tan bark that exfoliates revealing attractive brown inner bark, which provides outstanding winter interest.

Leaves are narrow, shiny, ovate-oblong, and are medium-green in color.  Heptacodium miconioides is rapidly increasing in popularity as an ornamental shrub. As an added bonus if your goal is to attract butterflies the plant is a good source of nectar.
