== Description == ''Quercus bicolor'' grows rapidly and can reach {{convert|60|to|80|ft|abbr=off|sp=us|order=flip}} tall with the tallest known reaching {{convert|29|m|ft|abbr=on}} and lives up to 285 years.<ref>{{Cite web |title=Eastern OLDLIST of maximum tree ages |url=http://dendro.cnre.vt.edu/olds/detail.cfm?genus=Quercus&species=bicolor}}</ref> The [[Bark (botany)|bark]] resembles that of the white oak. The [[leaf|leaves]] are broad [[ovoid]], {{convert|12|β|18|cm|frac=4|abbr=off}} long and {{convert|7|-|11|cm|in|frac=4|abbr=on}} broad, always more or less glaucous on the underside, and are shallowly lobed with five to seven lobes on each side, intermediate between the [[chestnut oak]] and the [[Quercus alba|white oak]]. In autumn, they turn brown, yellow-brown, or sometimes reddish, but generally, the color is not as reliable or as brilliant as the white oak can be. The [[fruit]] is a [[peduncle (botany)|peduncled]] [[acorn]], {{convert|1.5|β|2|cm|in|frac=8|abbr=on}}, rarely {{convert|2.5|cm|in|sigfig=1|abbr=on}}, long and {{convert|1|β|2|cm|in|frac=8|abbr=on}} broad, maturing about six months after pollination.<ref name=tammy>{{eFloras|1|233501012|Quercus bicolor |family=Fagaceae |first=Kevin C. |last=Nixon}}</ref> Good crops of swamp white oak occur every 3 to 5 years, with light crops during intervening years. The minimum seed-bearing age is 20 years, optimum age is 75 to 200 years, and maximum age is usually 300 years. Because the seed of swamp white oak is not dormant, it germinates soon after falling. Seed collections should be made soon after ripening in order to delay early germination. These acorns are difficult to store without germination or loss of viability occurring. Sound acorns have a germinative capacity between 78 and 98 percent. Gravity, rodents, and water are the primary dispersing agents (4,10).<ref>{{Cite web|title=Swamp White Oak|url=https://www.srs.fs.usda.gov/pubs/misc/ag_654/volume_2/quercus/bicolor.htm#:~:text=The%20fruit%2C%20an%20acorn%2C%20matures,1.25%20to%203.25%20in)%20long.}}</ref> Swamp white oak may live up to 300 years. {{Gallery |Image:Quercus bicolor JPG1L.jpg|Leaves |File:Swamp White Oak Quercus bicolor Bark Closeup Vertical.JPG|Bark }}
