Distribution
L. diffusus ranges from southeastern North Carolina to southern Florida, and west to Mississippi.[1]
Ecology
Habitat
In the Coastal Plain in Florida, L. diffusus can occur in longleaf pine-scrub oak sand ridges, sand pine scrubs, deciduous scrub oak barrens, sand pine woods, and live oak-palmetto scrubs. L. diffusus has neither a significant positive or negative response to agricultural-based soil disturbance in South Carolina coastal plains communities.[3] Associated species include Carya floridana, Lechea, Chamaecyparis, Quercus virginiana, Q. laevis and Q. incant.[4]
Like many other legumes, L. diffusus has root nodules that contain nitrogen fixing bacteria that provide the plant with nitrogen, even in poor soils.[5]
Phenology
L. diffusus flowers from March through May and fruits from June to July.[1]
Seed dispersal
Seeds are dispersed by wind and animals.[6]
Fire ecology
Responds quickly to soil disturbance and fire.[7]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Lupinus diffusus at Archbold Biological Station:[8]
Apidae: Bombus griseocollis
Megachilidae: Anthidiellum notatum rufomaculatum, A. perplexum, Megachile exilis parexilis
Use by animals
The legumes are toxic to livestock[5]. Foliage is eaten by aphids and caterpillars.[6]
