Won't bark on Zelkova be a give-away.
MAYBE in person. But I find that -if bare- the species are hard to keep apart. In fact, I recently dug a zelkova from my growing field for a friend. Told him to let me know once spring is around what came out: Was not sure whether siberian elm or zelkova, both of which I have in the field and in winter I am not convinced I can keep them apart!

I see a lot of Pumila..almost NO zelkova.

Pumila, to me... has a shinier, dark grey layer.. like UNDER where any "barking" takes place.

But you're right.. trying to do that IN PERSON in pretty tricky...

Using pictures?.... Only twice as tricky!!!

Ulmus parvifolia perhaps fares better in milder climates. Where you live, the temperatures rarely go below 0° C if I'm right.
Almost correct @AlainK Nights in winter regularly get down the -3C and occasionally -5C most winters, rarely a few deg lower. 9C below freezing is a record cold here.

I have seen some growers from much colder places saying that Chinese elm can be affected by colder temps. Does this mean that Zelkova is more cold tolerant?
I have also wondered if the problems of lack of ramification, long internodes, etc with my Zelkova might be related to the variety or provenance.
I see many great zelkova bonsai so I know it must be possible but nothing I've tried has worked with the trees I have which obviously leaves a negative impression. All my plants are descended from a single seedling I grew so maybe there are strains that are better for bonsai? Maybe it is just that I am not doing it right?
