Discussion
Of conservation concern.
Vegetative reproduction is predominant, forming large clones from adventitious buds on shallow roots. Large, old plants ("small trees") are apparently rare in the field. Florida plants begin growth about a month before Missouri plants (J. W. Day 1975). Leitneria floridana is successfully cultivated as far north as Chicago, Rochester, and Boston.
The wood (sp. gr. 0.21) is lighter than cork (sp. gr. 0.24); it is used locally for fishnet floats or bottle stoppers.
