I recently bought a tree at Lowe's in Dallas. The tag said Texas Red Oak.
The tag also said Quercus borealis (Q. rubra). The tree can from a grower in East Texas. I know that only two red oaks do well in our alkaline soil, the Quercus texana, and the Quercus shumardii. So I don't know what I have. The Q. borealis or Q rubra is the scientific name for a red oak, but it could be one that won't grow here. For what is worth I planted it. It has nice red color.

I've got 3 well established red oaks and I asked a few months back about how to determine whether they were Texas or Shumard. I believe the answer I got was that Shumards typically have a deeper cut pattern in the leaves. Short of contacting the grower where your tree came from I'm not sure you'll ever get a definitive answer as to what exactly you have. Taking a leaf to a few nurseries that carry both in order to compare might be helpful. Hope you enjoy the tree as much as I do mine!

Quercus borealis is Northern Red Oak (unless I'm WAY off here) and those are bad news in our area. They don't do well in the long term in our alkalai high-calcium soils.

Texas or Shumard red oaks do brilliantly here. Northerns OR a cross-polinated hybrid of Texas or Shumard crossed with Northerns will also not do well.

Typically they grow for a while (a year or three), then start yellowing-out mid to late summer and eventually just get sick and die.
