The Red osier dogwood (Cornus sericea L.) is a popular North American ornamental shrub, often planted also in Slovenia. Subspontaneous occurrence of the species in Slovenia is known for two decades, but only in recent years, we can recognize it as an invasive species. The Red osier dogwood is currently known from numerous localities in the wider city area of Ljubljana and also from two sites in the Gorenjska region. It occurs in wetland habitats, particularly in the vicinity of settlements, where the shrub is planted for ornamental purposes. To limit the invasion of the Red osier dogwood, timely measures should be taken. We also publish the updated determination key for the genus Cornus in Slovenia.
