The US may not have the climate, but Mexico might.

Interesting tree, Jerry. Looking up the flowering ash, we are told its cold hardiness zones are 6 to 9 and its heat zones are 4 to 9.

Looking at the overlap, we find the Sacramento Valley (Northern California) Oklahoma/Kansas east through Missouri to Virginia/North Carolina (except for colder Appalachia).

Zone 4 for cold in my area, so no chance here near Canada. More concerned about the longer term water and soil moisture issues being faced in the US. We tried ash trees here (to replace the elms), but all cut down due to emerald ash borer killing them. Lost majestic elms to Dutch Elm disease (insects bore into tree and kill it). So still looking for trees that can provide a good canopy–in order to get natural AC outdoors along streets and over sidewalks.

Hickory does well here In the upper Midwest. I’m partial to the shagbark hickory.

The ancient forests in the State of Guanajuato, where I live, were Encino robusta and Encino Laurel, glorious big canopy trees. 95% of them were cut down to fuel the smelters of the mines of Guanajuato, the source of most of the wealth that powered the Spanish Hapsburg empire. I am regrowing them.
These ash trees are fascinating, I will consider introducing them after I get their seniors in priority going!
Thanks.

Near as I can figure, those are oak trees related to the California live oak. Does this sound right?

Yes, they are very distant cousins, one at the northern end of what USAians call the Mohave Sonora desert, and the other at the far southern end of the same huge arid zone they call the Bajio.
