Siberian Elm is not Chinese Elm
It happens all the time, people call me and tell me about trees that are so big that they can’t get their arms around them and, unrelated but still slightly humorous, they tell me about their Chinese Elms. For the record, I have seen many trees that you can’t get your arms around (which doesn’t make that nutty measuring system any less ambiguous), but the Chinese Elms that I hear about have never, ever, ever, not once, actually been Chinese Elms – they have always been Siberian Elms.
I have gotten used to it now. If someone says they have a Chinese Elm, I just assume that it is a Siberian Elm. It isn’t that big of a deal, except that there really is a Chinese Elm and I often wonder if the next call about a Chinese Elm will, in fact, yield a Chinese Elm. I like both American Elm and Siberian Elm and assume that I would like Chinese Elm as well, and I don’t want to miss my chance to mill one if it ever comes along.
The elm issue moved to the forefront after a recent trip to the Missouri Botanical Gardens when I ran across an actual Chinese Elm conveniently marked with a little official sign. I have never seen one in real life, at least that I know of, and this was a great opportunity for a close-up view of a confirmed Chinese elm tree. I took that opportunity to snap some photos for comparison. Nonetheless, just assume that your Chinese elm is actually a Siberian elm, unless it looks a lot like the photos below.
