Because of limited seed quantities from these hybrids, L. leucocephala K67 is used as a model for the genus. In Florida, white leadtree is a prohibited species and therefore is not used in commercial applications in the state.

[25], In urban areas, it is an especially unwanted species, growing along arid roadsides, in carparks, and on abandoned land.
