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.

This plant is a legume and its roots have nitrogen-fixing nodules on them. It is useful on nutrient poor soils. Baptisia simplicifolia is a Florida endemic and is listed as Threatened by the FDACS. Treat as a small shrub even though this is not woody or use as a background plant in a wildflower garden.

All perennial Dicerandra species in Florida a rare and endangered. They appear to be closely related and form hybrid swarms if grown in a common garden. To protect the genetic purity of these rare plants, please do not grown them. Wildflower garden.

If a single plant of similar stature and flowers is desired, consider flatwoods plum, Prunus umbellatus. Based on BONAP and ISB maps, the range of this species covers much of the southern and south central US with some outliers to the north and west. In Florida, it has been documented in many counties in the northern half of the state, and this author is aware of it being in others.  It appears to be appropriate to consider this species native throughout this part of the state. Plant as a screen where its suckers are welcome (woodland edges, casual but large garden settings)

Specimen plant, screen plantings, sometimes with unusual or weeping form.
