ksgobbler... Had a fellow from Osage City KS send me scions of a Swamp White X Overcup hybrid (Q.x humidicola) that I grafted onto SWO understock many years ago (later got another one from Columbia MO)... would suspect that it would fare well in a flood-prone setting... mine is in a low wet spot in the yard, but I've mostly been planting out bur and bur-hybrids around the farm for wildlife purposes. Did pick up a few sprouting acorns from the x humidicola this spring and potted them up for a buddy who's got a swampy spot that he wants to plant some oaks in, for trial.
