i took 20, plastic bag with damp paper towel, sitting in frig. once cools down outside. thought would put in some soil in garage and see what happens. Thx for response.Davewp .... after seeing the acorns you removed from the tree I think your belief it is primarily SWO is a better call than my suggestion of .... English Oak (EO acorns are usually elongated - couldn't tell with cap on tree - as opposed to gum-drop shaped SWO). If it was in a parking lot island or in small area on edge of lot it could be a hybrid. I'd be starting some trees off that tree .... it appears to be a winner. Good luck! Also, I would watch the tree each year to determine it's fruiting frequency and I'd try to learn who/when it was planted (if the lot is new withiun the last 8-10 years, it might not be too difficult to learn who landscaped the lot). They should be able to tell you a lot more about the tree. Again, good luck ...that is an exciting find.
I have some seedlings from a tree that looked just like that. I was told they were columnar English Oaks. I have one growing on my land and 3 more in 1 gal pots that I'll plant this year. I found the trees outside the Federal courthouse in OKC when I was on jury duty. The acorns produced small seedlngs but the one at my land is tubed and it's about 18" tall. Those leaves don't look quite like the ones I have though because of the white on the back of the leaf and there are many more lobes on that leaf than on the ones i've got. Beautiful tree though. And good sized acorns shaped just like the ones pictured.View attachment 20529
