Although naturally found on low moist sites, this tree will also perform well on moist upland sites. We have a few of these trees growing in our town park and they survive the droughts with no problem. Overcup oak has a nice form with a rounded canopy. The acorns resemble those of Bur oak.

Found almost always mesic, poorly drained sites / wetlands. Here in Florida, it's native range includes mostly the panhandle region.

I guess the reason for the name varies... My source the word lyrata refers to lyre shaped leaves.

Rounded growth shape. Fall leaf colors vary, yellow, red, brown.
