Cornus amomum Cornus amomum

Cornus amomum, commonly called silky dogwood, is a medium-sized deciduous shrub that is typically found in moist lowland areas, swamp borders, floodplains, shrub wetlands, and along streams and ponds in Eastern North America (New Foundland to Ontario south to Missouri, Mississippi and Florida). Twigs and leaf undersides have silky hairs, hence the common name. This dogwood typically grows to 6-12’ tall with an open-rounded form.

The bark in young trees is red-purple and smooth.  As the tree/shrub ages, the bark turns brown and develops shallow fissures.

Genus name comes from the Latin word for horn (reference to hard wood). This shrub is also commonly called swamp dogwood in reference to habitat and kinnkinnik (tobacco) in reference to a prior use of shrub bark by Native Americans as tobacco.
