Verbena speciosa 'lmagination' 'Imagination' Verbena

Edward F. Gilman


This verbena is a perennial well suited for Florida landscapes, especially those that receive infrequent irrigation. It won the All American Selections award in 1993. Deep violet-blue or purple flowers borne in clusters at the top of this 12-inch-tall ground cover stand out against the soft, fine-textured foliage. They cover the plant with purple. Stems creep along the ground and root to bind the soil together, helping prevent erosion.

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. Occasional fertilizer applications will help keep the foliage green and will promote flowering.

Verbena tenuisecta is very similar.
