Titi swamp is a swamp habitat in Florida and Georgia where species of Cliftonia monophylla ("Buckwheat tree" or "Black titi") and/or Cyrilla racemiflora ("Ironwood" or "white titi") predominate.
The town of Ty Ty in Tift County, Georgia is named after one of the numerous small creeks named, in turn, for the presence of these scrubby trees in their boggy fringes.
