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.

There are three subspecies included in this description.  Together, they are found in all coastal counties of Florida and many inland ones.  As a grass, it is likely undercollected and it has likely been excluded by many agricultural practices, so at least one of these subspecies is potentially native throughout Florida.  Muhlenbergia capillaris var. capillaris is the subspecies that is most commonly available from nurseries.
