Cultivars of Quercus palustris:

• 'Sovereign' has lower branches that do not droop.
• 'Crownright' is similar to the `Sovereign', but with a more narrow and upright shape.

Comments:

In about the first thirty years, the branching habit of the native pin oak is truly unique. The upper branches are ascending, the middle ones horizontal, and the lower ones drooping. The drooping lower branches make pin oak a poor street tree. It is better placed in locations where the lower branches will not be a nuisance.

Suitable for bonsai.
