Viburnum rufidulum is noted as a food source for most birds, some mammals, even including foxes. The fruits, leaves, and twigs can be eaten by herbivorous animals such as the white-tailed deer (Odocoileus virgianianus) in upland forested areas (Sallee, 2002: 15).
Historically the Plains Apache utilized the plant as a food source (one of 48 plants documented in the study), though it is unclear exactly what part of the plant was used (Jordan, 2006: 28).

Viburnum rufidulum can reach 3.5 m in height and produce seeds after 5 years (Bonner et al., 2008: 1163). The leaf petioles and undersides have rusty hairy. The oval leaves are dark and shiny on the upper surface and can grow up to 10 cm long (Hunter, 2000: 174). The flower buds are a reddish brown and the flowers are white and occasionally even pinkish. The flowers are arranged flattened, rounded and in convex cymes (a flat-topped cluster of flowers in which the central or terminal flower opens first)(Bonner et al., 2008: 1163). The flowers can grow up to four inches across. (Hunter, 2000: 174) The flowering dates are primarily from March to June depending upon the region. (Bonner et al., 2008: 1163). Pollination is by insects (Bonner et al., 2008: 1163). The dark blue fruits are approximately 13 mm in length, elliptical (oval) and slightly flattened (Hunter, 2000: 174). The fruit ripens September to October (producing 5,200 kg dried fruits/kg) and seed dispersal can occur in December (Bonner et al., 2008: 1163, 1165).

Viburnum rufidulum does not tolerate water with a high concentration of chloride. In one experiment, Viburnum rufidulum suffered 80% leaf burn when watered with reclaimed water, although the roots were not affected (Parnell, 1990: 378).

Viburnum rufidulum, also known as the rusty blackhaw, blue haw, rusty nanny-berry, or southern black haw, is a flowering species of shrub or small tree that is common in parts of the Eastern and Central United States. It produces attractive flowers and fall foliage, as well as fruits that are popular with some species of bird.
Description[edit source | edit]
Leathery deciduous leaves are simple and grow in opposite blades ranging from 0.5-3 inches in length and 1-1.5 inches in width. Petioles are "rusty hairy" with grooves and sometimes wings. Leaf margins are serrate. Autumn leaf colors are bronze to red.
Distribution[edit source | edit]
The Rusty Blackhaw prefers dry habitats with elevations generally below 750m.
It grows in Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Kansas, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, Ohio, Oklahoma, South Carolina, Tennessee, Texas, Virginia, and West Virginia.
