(Verbena) Give your annual combinations a bold splash of royal blue with SUPERBENA® COBALT™. As close to blue as they come, the clusters of small deep purple flowers make up the bloom of COBALT™. Standing 6-12 inches tall and spreading/trailing up to 18-36 inches, SUPERBENAS® make a great selection for hanging baskets and container combinations. The SUPERBENA® series of verbena are the most vigorous in our collection. These drought-tolerant, heat-loving annuals bloom from early summer well into fall. Planted in full sun to part shade locations with regular watering. SUPERBENA® COBALT™ verbena has been bred for excellent disease resistance and continuous blooms with no deadheading required. Fertilize with a continuous release fertilizer when planted and repeat about every 6-8 weeks. Container plantings require more fertilizer than landscape plantings. COBALT™ may benefit from a light trim every 4-6 weeks promoting more branching for a fuller plant. Enjoy the butterflies and hummingbirds that visit your flowers of SUPERBENA® COBALT™.
