    Sewer vine is another non-native invasive vine in Florida, very similar to skunk vine, Paederia foetida, in smell, appearance, and behavior. This southern Asia native is is now locally abundant in Dade County. It flowers in the spring through the fall (Wunderlin, 2003).

    Appearance: Semi-woody, climbing, twining vine, sometimes shrubby.

    Leaves: Opposite, broadly lanceolate to elliptic, with relatively long petioles and smooth margins.

    Flowers: Tubular, 7–11 mm long; pinkish to pale lilac with a purple throat, 5-lobed.

    Fruit: A flattened, orange to yellow, papery berry, to approximately 1 cm (0.4 in) in diameter; seeds winged.

    Ecological threat: Dangerous to native species as it can out compete and shade out even large trees. Spreads readily by seeds and by rooting at stem nodes. Stems often run beneath leaves and surficial duff, rooting as it goes. FLEPPC Category I
