The cedar-hawthorn rust is common all across the Midwest and Eastern United States. Its overwintering capability allows it to thrive in seasonal climates with harsh winters. The pathogen that causes it, Gymnosporangium globosum, prefers humid and cloudy conditions for developing growth and the spores depend on rain and wind to be dispersed to its alternate host.
