Description
C. florida is a perennial shrub/tree of the Cornaceae family native to North America and Canada. [1]
Distribution
C. florida can be found in the south- and mid-eastern United States, as well as the Ontario region of Canada. [1]
Ecology
Habitat
C. florida thrives in dry to moist forests and wetlands [2], and does well in understories. [3]
Phenology
C. florida flowers February-April, October, and November. [4] Bark is grayish brown, reddish brown, or black, rough, broken into square blocks; leaves deciduous, opposite, simple, nearly hairless and smooth to touch on upper surface, finely hairy on bottom surface; inflorescence is many flowers crowded into a head, subtended by 4 large and showy white-pink petal-like bracts; fruit is an elliptical drupe, 1-2 seeded, bright red or yellowish at maturity, usually several are crowded together. [5] C. florida is a bird-dispersed species. [6]
Fire ecology
C. florida is not fire resistant, but has a medium fire tolerance. [1]
Use by animals
C. florida is somewhat palatable to browsing animals, not highly palatable to grazing, and inedible for humans. [1]
Diseases and parasites
C. florida has been impacted since the 1980s by widespread infection by the dogwood anthracnose fungus (Discula destructive). [2]
Conservation and Management
C. florida is listed as endangered by the Maine Department of Conservation Natural Areas Program, exploitably vulnerable by the New York Department of Environmental Conservation, Division of Land and Forests, and threatened by the Vermont Department of Fish and Wildlife Nongame and Natural Heritage Program.
