I believe you, but I don’t see Fraxinus that look like THAT... all mine are compound-leaved... not ideal...Fraxinus sp., ash tree. Depending of your location, it can be a species from the american part of the genus (section Melioides or Pauciflorae)...
If you can take a picture of the flowers, it could help ;-)
Absolutely, the things I’ve seen done with Fraxinus is amazing! I, also, LOVE the bark.Pretty confident that will be ash. The leaves pictured are not entire leaves which is probably causing some confusion.
Ash are usually dismissed as bonsai because of the larger compound leaves but some growers down here have made some really great bonsai. The bark gets character quite quick and trunks and branching develop fast here. They are defoliated before a show and shown just as the new leaves are emerging and can look stunning.
Google Lens (baked into the Android camera app) is also remarkably effective.Hey for those on this thread and OP, there's a really cool free app called LeafSnap I found out about a few months back that I use all the time. It's pretty accurate and can locate based off leaf, flower, bark, or fruit. It will also give you alternate plants it could be!
