Introduction
This native verbena is well suited for along the coastal areas of Florida but is now in danger of extinction in the wild. Its tolerance to salt air and water makes it a great perennial dune stabilizer. It adds color to the ground year-round. Purple or lavender flowers borne in clusters at the top of this 12-inch-tall ground cover stand out against the fine-textured foliage. Stems creep along the ground and root to bind the sand together. Sand builds up around the stems and foliage, helping prevent wind from blowing it back from the beach.

Use and Management
To establish a solid ground cover, plant about 4 feet apart. Stems creep along the soil and plants will form a complete cover 18 to 24 months after planting. Plant in the full sun for fastest growth and best flowering. Foliage remains dark green with little or no care once plants are established. Although the plant is native to beaches, it should perform well in dry, inland landscapes in full sun.
Pests and Diseases
Few problems should impact this native verbena, provided it is not irrigated too much.
