Varieties: none[1]


Penstemon multiflorus has cauline leaves with basal leaves that are petioled. The inflorescence of many nodes with anther cells dehiscing by short proximal slits.

The root system of Penstemon multiflorus includes root tubers which store non-structural carbohydrates (NSC) important for both resprouting following fire and persisting during long periods of fire exclusion.[2]. Diaz-Toribio and Putz (2021) recorded this species to have an NSC concentration of 109.5 mg/g (ranking 49 out of 100 species studied) and water content of 57.9% (ranking 37 out of 100 species studied).[2]


This plant ranges from south-central Florida and southern Alabama, south to southern Florida.[1]



P. multiflorus occurs in sandy or loamy soil, preferring areas with high light levels.[3] It can be found in oak-pine-palmetto flatwoods, cabbage palm hammocks, and open stands of longleaf pine and scrub oak.[3] It can also occur in disturbed areas, including slash pine plantations, firebreaks, and roadsides.[3] Associated species include sand oak, live oak, saw palmetto, longleaf pine, scrub oak, and slash pine.[3]
