Cissus verticillata (possum grape vine).
Cissus verticillata is a large, climbing species cultivated as an ornamental and medicinal plant around the world. It is native to Mexico, Central America and the Caribbean. Once established, C. verticillata grows climbing over the top of the canopy and supporting itself by means of coiled tendrils, or scrambling over the ground. It is common to find this species engulfing entire trees. If the plant is cut, the remaining branches and stems can develop aerial roots that will find their way to the ground, regenerating new. C. verticillata is regarded as a weed in areas within and outside its native distribution range. It was reported in the Lower Rio Grande Valley in Texas in 2003 and may pose a potential weed problem in the citrus groves there and in Florida.
