Epipremnum

Epipremnum aureum is a climbing aroid in the genus Epipremnum (Araceae), sold under the name pothos. It is native to Mo'orea in the Society Islands and climbs trees by clinging with aerial roots. Plants sold as houseplants are in their juvenile stage, with heart-shaped leaves often variegated with yellow or other colours. Once a stem climbs and matures, the leaves reach 30 to 40 cm long and develop pinnate divisions, and outdoors the vines can grow to about 12 m. It was formerly treated as Scindapsus aureus, and some authors treat it as a cultivar of E. pinnatum. All parts contain needle-like calcium oxalate crystals, and chewing the plant causes pain and swelling of the mouth, drooling, vomiting and difficulty swallowing, so keep it away from pets and children. It has naturalized in many tropical regions and is listed as a Category II invasive species in Florida.
