Sun-loving verbena (Verbena x hybrida), a butterfly favorite, is sometimes described as a see-through plant, because its long flowering stems do not obstruct the view of other bedding plants and flowers. Depending upon the variety, verbena grows in U.S. Department of Agriculture plant hardiness zones 7 through 10 as a perennial, and in USDA zones 6 and below as a tender annual outdoors or in containers. Verbena does best in a sunny and well-drained spot. Considered a low-maintenance plant, it generally requires little care beyond the basics.Garden verbena, or landscaping vervain, is a simply beautiful flower and will be a perfect match for gardens and container-based growing alike.
