With native American Cottonwood trees is there a female and male tree and if so how do you tell the difference

Answer 1

The first answer is correct. There are over 300 species of Populus, including cottonwoods, poplars and aspens.

I would say, however, that it is really not that difficult to tell them apart with flowers. Look closely at the catkins... (you may need a hand lense) if you see tiny stamens with anthers you know you have a male; if you see only styles and stigmas, you have a female.

It should be noted that this family (Salicaceae) reproduces mainly vegitatively (not by seed).

Answer 2

yes, male and female trees
only a really good expert can tell the difference unless they are in bloom, then the one producing the cotton is the female tree!

Answer 3

at flowering stage it is easier to identify than at the vegetative stage
