Native to: Mexico
Coral vine was introduced into Florida as an ornamental around 1924 and is often grown as a landscaping plant in the southeast and Gulf regions of the United States. It produces beautiful light pink to dark pink flower clusters. Coral vine is used for its vining habit to cover fences or climb trellises. It tolerates poor soil and a wide range of light conditions, making it a very successful invasive plant species. Coral vine has become an invasive species and has increased in abundance in south and central Florida.Description
There are many methods of reproduction and dispersal that aid in the survival of coral vine. Not only is coral vine a prolific seed producer, but the seeds will float on water, dispersing the plant to new locations. Fruits and seeds are eaten and spread by wildlife such as birds, raccoons, and pigs. Coral vine also forms underground tubers and large rootstocks, which will resprout if the plant is cut back or damaged by frost. Antigonon leptopus is a smothering vine that invades disturbed areas and forest edges, quickly covering nearby plants and structures.
The first step in preventative control of coral vine is to limit planting and remove existing plants within the landscape. Remove existing coral vine and replace with native vines such as cross vine (Bignonia capreolata), Florida milk pea (Galactia regularis), Carolina jessamine (Gelsemium sempervirens), coral honeysuckle (Lonicera sempervirens), and purple passionflower (Passiflora incarnata).Cultural/Physical
If possible, removal should occur before seeds are produced. Care must be exercised to prevent seed spread and dispersal during the removal process.Mechanical
There is limited research and data on mechanical control of coral vine. Continuous cutting will be effective in depleting food reserves, but this process will take several cycles. If plants are physically removed, underground tubers must be removed or plants will re-sprout.Biological
There is limited research and data on biological control of coral vine.Chemical
