Abstract
The flowering dogwood (Cornus florida L.) is an important understory tree native to south and east pine and deciduous forest ecosystems of the United States and Canada (Jenkins and White 2002). This tree species has important cultural values associated with its use by Native Americans in natural remedies from bark and root extracts, dyes, and arrow shafts (Little et al. 1980; King 2003), and it is a popular ornamental landscape tree planted in the southern and eastern United States. Studies have reported localized decline of dogwood populations due to the introduction of the fungus Discula destructiva Redlin, the causal agent of dogwood anthracnose in the eastern United States (Daughtrey et al. 1996; Oswalt et al. 2012).
