It's not Black oak, it's either Scarlet Oak, Pin Oak, or Shumard Oak. My first guess would have been Pin Oak from the leaves. But some Shumard Oaks usually have that branch crown. Scarlet Oak usually has more dark colored and fissured bark, especially on branches and the leaves don't look as close to that IMO. So I think it's likely between Pin Oak and Shumard Oak. More likely Pin Oak because Shumard Oak usually has larger "bulk" at the top center of the leaf. Some Pin Oaks don't have great fall color and others can have great fall color. How big are the acorns? Pin Oaks have small acorns and Shumard Oak has large sized acorns.

whats hard about it... you have a living oak ... not much to complain about that per se ... if you feel yourself becoming a plant collector ... wanting true named plants.. just find better sources .. that was my point... not many years back.. most peeps couldnt get anything from AD to grow leaves [in other words dead stock] .. let alone be true to name... they have made progress in that regard ... ken

Lucky There are a few blackjacks in my area but southern red oak is the most common red oak species. I've got southern reds native on my place but no blackjacks native although I have a planted one. Southern reds are prolific, I find loads of volunteers. The first year seedling foliage on SOME CAN look like mature blackjack foliage, but I watched them for 30 years and they always turn into southern red oaks lol. The other day I found my first blackjack seedling. My planted tree has been fruiting for several years and I've had my eye out but this is a first. There is no mistaking, the seedling is definitely blackjack, its foliage looks exactly like the parent tree. Around here, southern red oak blooms way earlier than blackjack, some years getting frozen. I think the tree in the OP is probably falcata or a hybrid, but I'm no oak expert.

Oddly there aren't any oaks in the area that I know of, although on paper they should do great. The area used to be farmland, and the original developers planted mostly black pine and maple. The trees are mostly maple, locust, white pine, Norway Spruce, or trees with seeds delivered by small birds (eg. black cherry and eastern red cedar). No branches I can readily reach, due to this incident. I had been considering planting a Scarlet x Willow Oak Hybrid (Quercus coccinea x phellos) or buying a Red Oak seedlings from the NH state nursery. Interested in Scarlet Oak, but can't find a local source that sells them other then in bulk. (And I'm running out of room for bundles of ten or more trees).
