Coral vine is native to Mexico, regularly escaping into bushlands and creek edges in South-East Queensland. A perennial vine to 12 metres in length, climbs by tendrils. Attractive green heart-shaped leaves to 10 cm. In summer the vine produces large branching flower stalks (racemes) of small flowers the sepals of which provide the colour. It will propagate from seed or cuttings. It is a rampant weed, capable of suffocating native vegetation.
