Q.What Is The Difference Between A Forest Fire Black Gum Tree And A Wildfire?
I can find little info on Forest Fire black gum tree. Is it male or female cultivar?

Wildfire seems to boast a slightly larger spread. They do not give the sex for either specimen, so they are likely not determined cloned. Unless you find and compare them in person, you will not likely know until it flowers. Usually, if it is from a known-sexed clone... They will list it.
