Growth

In the wild, it commonly grows in areas of damp soil, such as wetlands. It is a medium to tall deciduous shrub, growing 1.5-4 m tall and 3-5 m wide, spreading readily by underground stolons to form dense thickets. The branches and twigs are dark red, although wild plants may lack this coloration in shaded areas. The leaves are opposite, 5-12 cm long and 2.5-6 cm broad, with an ovate to oblong shape and an entire margin; they are dark green above and glaucous below; fall color is commonly bright red to purple. The flowers are small (5-10 mm diameter), dull white in color, in clusters 3-6 cm diameter. The fruit is a globose white berry 5-9 mm diameter.

Uses

Cornus sericea is a popular ornamental shrub that is often planted for the red coloring of its twigs in the dormant season.

Species

It is a variable species, with two subspecies commonly accepted:

  • Cornus sericea subsp. sericea - throughout the range of the species. Shoots and leaves hairless or finely pubescent; flower petals 2-3 mm.
