Taxonomic notes
Synonyms: Petalostemon carneus Michaux[2]
Varieties: none[2]
There are three varieties. Dalea carnea var. gracilis and D. carnea var. alba have white flowers, while Dalea carnea var. carnea has pink flowers. The most widespread variety is D. carnea var. carnea.[3]
Description
Herbaceous plant with several elongate, radiating branches spreading through grasses, not erect. Decumbent. It has a turbinate lignotuber.[4]
Distribution
D. carnea occurs from central Georgia south to southern peninsular Florida.[1]
Ecology
Habitat
It is found in wet pine flatwoods, edges of cypress swamps, edges of pine palmetto habitats, Longleaf pine uplands, and in dry pine woods and savannas. It is also found in human disturbed areas such as open fields, embankments, and areas that have been logged and clear cut. It is associated with areas that have drying loamy sand, loose sand, where limestone underlies the surface in flatwoods, and well-drained slopes of Longleaf pine forests.[4]
D. carnea was found to decrease its occurrence or become absent in response to soil disturbance by agriculture in southwest Georgia. It has shown resistance to regrowth in reestablished pinelands that were disturbed by agriculture.[5] Additionally, D. carnea was found to be a decreaser in its short-term response to single mechanical soil disturbances as well as in its long-term response following cessation of repeated soil disturbance.[6]
Associated species includes Myrica cerifera, Eupatorium, Polygala, Clematis, Asclepias, Liatris, Indigofera caroliniana, cowpeas, and others.[4]
Dalea carnea var. gracilis is an indicator species for the Panhandle Silty Longleaf Woodlands community type as described in Carr et al. (2010).[7]
Phenology
D. carnea has been observed flowering from June to November with peak inflorescence in July.[4][8]
Seed dispersal
This species is thought to be dispersed by gravity. [9]
Fire ecology
Populations of Dalea carnea have been known to persist through repeated annual burns.[10]
Pollination
Bumblebees and honey bees has been observed on D. carnea.[4]
Conservation, cultivation, and restoration
D. carnea should avoid soil disturbance by agriculture to conserve its presence in pine communities.[5]
