Quercus macrocarpa
bur oak

Notes:

Faster-growing than Q. bicolor, though Dirr/Warren seem to contradict this. Symmetrical, uniform crown even when young (though columnar in youth). Good root behaviour is conditional on soil not being compacted. May establish slowly after transplanting.

Resistant to oak wilt. Branch strength debated (UFL vs. Cal Poly). Good compartmentalizer of decay.

Hybridizes with Q. robur to form Q. × macdanielli; in particular, 'Clemons' (Heritage) is noted for dense habit and unusually vigorous growth for an oak.

'JFS-KW3' (Urban Pinnacle) is upright pyramidal and narrower than the species, with notably small acorns (an important consideration when acorns of the species can be as big as golf balls) and particularly clean and disease-resistant foliage.
