A description of Phytolacca americana is provided in The Flora of North America. It is a robust, perennial herb that grows 1-3 m tall. The roots are thick and fleshy. The leaves have an alternate pattern, glabrous texture, entire margin, and lanceolate to elliptic shape. They grow 3-12 cm wide and 8-30 cm long with a rounded base. The petioles are 1-5 cm long. Racemes are 5-20 cm with bracteate pedicels. The flowers are perfect, colored green to white, and 2-3 mm long. They include 5 sepals, 5-30 stamens, and a superior ovary. The berries are 5-12 carpellate, purplish-black, 4-6 mm long, and 7-10 mm in diameter. The seeds are lustrous black, 2.5-3 mm long, and flattened.[1]
Distribution
This plant is an abundant native weed that occurs throughout eastern North America.[1]
Ecology
Habitat
P. americana has been found in hydric hammocks, swamp edges, coral limestone, sandbars, mangrove swamps, and floodplain forests.[2] It is also found in disturbed areas including disturbed coastal hammocks, along canals, farmlands, orange groves, landfills, burned longleaf pine-wiregrass flatwoods, pine-hickory camping woods, and along roadsides.[2] Associated species: Sabal, Quercus, Elaphrium, Swietenia, Dalbergia, Gouania, and Schinus.[2]
Phenology
This plant has been observed to flower from March through November, with peak inflorescence in May through July.[1][3]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Phytolacca americana at Archbold Biological Station:[4]
