Noteworthy Characteristics

Verbena is a genus of about 250 species of annuals, perennials and subshrubs from temperate and tropical areas of the Americas with a few from Southern Europe. They are grown for their showy flowers that are attractive to hummingbirds, butterflies, and other pollinators.

Genus name comes from a Latin name used for some plants in religious ceremonies and also in medicine.

‘Imagination’ is a verbena cultivar that is grown in St. Louis as an annual. It is noted for its profuse bloom of violet-blue flowers, its spreading-trailing stems and its deeply cut foliage. When grown as an annual, it flowers freely from late spring to fall. Violet-blue flowers in umbels (2” diameter) appear throughout summer. Although a hybrid plant, ‘Imagination’ is often commonly called moss verbena because of its similarity to Verbena tenuisecta.
