Coral Vine is an invasive species on St. John. It's extremely hard to get rid of because it can grow up from its network of thick underground tuberous roots, so you would need to get a hoe pick and dig out all the roots. It goes though cycles whereupon the vegetation is tick and then it dies back to where it is hardly evident. The good news is that it has a pretty flower and it only seems to grow along roadsides and at the periphery of cleared areas.
