You can do a COMBINATION SEARCH in our Native Plant Database to see vines native to Florida by choosing "Florida" from the Select State or Province slot, "Vine" from Habit (general appearance) and "Pink", "Blue", "Purple" and "Violet" from Bloom Characteristics.

For non-native invasive vines please check the webpage for Center for Aquatic and Invasive Plants from the University of Florida.

You can see more vines, some native and some non-native, on the Florida's Nature page.

If you don't find your vines in any of the above sources, please visit our Plant Identification page to find links to several Plant Identification forums that will accept photos of plants for identification.
