Beauty on the Dunes: What are those beautiful funnel-shaped lavender flowers with bright green foliage spreading out from the dunes with their long runners? It is a Florida native vine (Ipomea pes-caprae) and part of the Morning Glory family. They attract pollinators such as bees and butterflies. Sometimes you’ll notice a runner reaching more than 20 feet from the dunes. On the dunes, they form a large mat of green foliage with its roots helping stabilize the dunes and preventing erosion.
