Quercus bicolor
swamp white oak
Notes:
Leaves usually persist into winter, but 'Green Nova' (Sun Breaker) drops leaves cleanly.
Transplants best in spring (does not apply to planting from containers) and needs deep soil. No consensus on growth rate, with Stoecklein saying slow, JerseyYards.org and the USDA saying fast, and everyone else in between.
Stoecklein singles out this oak (and Q. macrocarpa) as tolerant of alkaline soils, but NCSU, JerseyYards.org, and the USDA contradict this.
