WHAT FLORIDA NATIVE PLANT IS BLOOMING TODAY?: PARTRIDGE PEA (Chamaecrista fasciculata)
Great for wildlife: Birds eat the seeds, pollinators attracted to nectar/pollen.
larval host: cloudless sulfur (Phoebis senna), gray hairstreak (Strymon melinus), orange sulphur (Colias eurytheme), sleepy orange (Abaeis nicippe), little yellow (Eurema lisa) and ceraunus blue (Hemiargus ceraunus) butterflies.
