Taxonomic notes

Synonym: Pluchea baccharis (Mill.) Pruski; USDA NRCS Plants Database


"Perennial or annual, erect herbs, stems erect, densely short pubescent, terete to obscurely angled, strict to freely branched. Leaves alternate, serrate, the teeth-callous-thickened, petiolate to sessile. Heads corymbose. Involucres hemispheric to campanulate, many flowered; bracts imbricate, in several series. Flowers all discoid, perfect, very small. Nutlets small, cylindric, 5-ribbed; pappus bristles whitish, capillary, minutely, antrosely barbed, 3-4 mm long."[1]

"Pubescent perennial, 4-11 dm tall, usually strict. Leaves oblong to elliptic-oblong, 3-9 cm long, 1.3-5 cm wide, obtuse to acute, auriculate-clasping sessile. Heads sessile or essentially so in glomerules in compact corymbs, the lateral branches usually overtopping the central. Involucres 3-6 mm long; bracts acute. Corollas pink. Nutlets black, 0.5-1 mm long, densely pubescent."[1]


P. rosea is distributed in the northern and central Bahamas, North America and the Caribbean.[2]



Habitats of P. rosea include swamp grasslands, river banks, edges of limestone sinks, and disturbed coastal prairies.[3][4] Associated species include Sapium sebiferum, Panicum virgatum, Symphyotrichum, Ludwigia linearis, Helianthus angustifolius, Rudbeckia nitida var. texana, Paspalum floridanum, and Rhynchospora.[4]

Pluchea rosea is an indicator species for the Peninsula Savannas community type as described in Carr et al. (2010).[5]


P. rosea has been observed flowering May through September.[6][7]
