FLIP: Florida Invasive Plants

Syngonium podophyllum

Common Name(s): American evergreen, arrowhead vine

Origin

South America

Ecological Impact

Can establish dense populations that displace surrounding vegetation. It has the ability to spread in the deep shade of intact forests, forming a dense mat on the forest floor as well as climbing trees. The stems by which it climbs are thick and fleshy giving them a weight much heavier than most native vines, thus potentially making trees top heavy and more susceptible to falling in a strong wind. Listed as a category I invasive species by Florida Exotic Pest Plant Council (FLEPPC).

Description

High climbing, epiphytic vine, stems 1-1.5 cm (0.5 in) thick. Creates a milky sap. Leaves alternate,  heart-shaped, to oblong, to ovate, to triangular. Mature leaves very deeply lobed. Flowers in a fleshy spathe, often several spathes clustered together. Flowers on a found column containing in the spathe and green in color. Fruits a red berry.

Identification Tips

History

Introduced to Florida for ornamental purposes.
