General Comments:

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.
