Casuarina glauca is widely cultivated in many parts of the world. Pistillate trees are very infrequent in the flora.

It is now considered a pest species in Florida because of root suckering. Its identification may be confused by the practice of some Florida nurserymen of grafting scions of Casuarina glauca onto rootstocks from the other two species.
