Seeds float and can be dispersed by water. Noted as a sand stabilizer being one of the first plants to colonize active dunes. Pan-tropical. Makes a nice groundcover in an informal dry yard. In nature, it is an important stabilizer of beach dunes.

Shade tree.  Narrow crown is said to make it a good choice for avenues, narrow entryways, and areas between houses.  Can be used as a large container plant.

This species is more common in adjacent states and occurs broadly in mid-western prairies.  Its range barely makes it into Florida.   The southern end of the range is likely determined by lack of winter cold.  The seeds germinate better with winter stratification. Delphinium caroliniana is listed as state Endangered in Florida.  It is not commercially available in Florida.  It might best be purchased from Alabama or Georgia seed sources. Wildflower gardens.

Range includes areas usually relatively near the coast in Southeastern United States west to Texas, north to North Carolina, and south to the Monroe County Keys; and Mexico,  the Neotropics and Bermuda. Rare in the northern parts of its range and in the Florida keys. Naturalistic areas especially near the coast.
