Here's an elm tree growing in our back woods. It just started blooming in the past couple days and I'm wondering which one it is so I can add it to the DB. I'll get pictures of its leaves later in the season.

These days, you are more likely to run across Slippery Elm (Ulmus rubra) in the woods than American Elm (Ulmus americana), but it's pretty difficult to tell them apart in the winter. The easiest way to separate them is by looking a the samaras, which should be developing in a few weeks.

The samaras of American Elm have fuzzy hairs along the edges of the wings, while the samaras of Slippery Elm are relatively smooth.

Ok, that should be easy enough. Thank you Kent! I will keep an eye on this tree and will be glad to get a confirmed ID in a few weeks.

Whichever Elm it is, those are great photo's!

Thank you.

Looks like what I have is the American Elm. Thanks Kent!
