How do you identify male and female trees?

It depends on what type of tree it is.

“Plants with both male and female flowers on the same plant are said to be monoecious (in the same house). The botanical term for plants that have the female flowers and male flowers on separate plants is dioecious (in two houses).”

That can actually be incredibly difficult to do. Sexuality in trees is quite complicated. There are some species in which individuals are unambiguously male or female, but there are many others in which an individual has both male and female capabilities. Sometimes that actually does mean that this tree has both functions; sometimes, though it will be functionally only male or female, even though it has the necessary anatomy for both. And there are even instances when a tree will change its functional gender over time.

I have two young persimmon plants. These plants need a male and a female to reproduce. So I would say they are of the dioecious kind.

@livingchoice You’d have to see it in bloom. Male persimmons have small flowers in clusters. Females have larger, single flowers.

Male trees do the boogaloo.

Female trees shake their booty.

Who knows?

It’s easy with the female ginkgo tree. The ripe fruit smells like dog poop, overripe cheese or vomit, depending on whom you ask.

Even the august New Yorker has something to say about this tree, its ferocious advocates and equally fearsome opponents.
