Viburnum dentatum, southern arrowwood or arrowwood viburnum or roughish arrowwood, is a small shrub, native to the Eastern United States and Canada from Maine south to Northern Florida and Eastern Texas.
Like most Viburnum, it has opposite, simple leaves and fruit in berry-like drupes. Foliage turns yellow to red in late fall. Localized variations of the species are common over its entire geographic range. Common differences include leaf size and shape and placement of pubescence on leaf undersides and petioles.
Larvae of moths feed on V. dentatum. Species include the unsated sallow or arrowwood sallow (Metaxaglaea inulta) or Phyllonorycter viburnella. It is also consumed by the viburnum leaf beetle, Pyrrhalta viburni, an invasive species from Eurasia.<ref>Viburnum leaf beetle, Pyrrhalta viburni (Paykull) (Coleoptera: Chrysomelidae) : Dispersal pattern of a palearctic landscape pest in New York and its distribution status in the northeastern U.S. and eastern Canada.

The fruits appear blue. The major pigments are cyanidin 3-glucoside, cyanidin 3-sambubioside and cyanidin 3-vicianoside, but the total mixture is very complex.<ref>Food colorants: Anthocyanins. F.J.
