Fill your summer with fragrant flowers with the Superbena® Imperial Blue™ Verbena. Tiny blue-purple blooms grow in clusters and feature scalloped petals that create a feathered appearance. Green foliage fills the spaces between the flowers and balances out the vivid blue blooms. This plant is not fussy and is rather adaptable. Verbena can effortlessly handle the challenging conditions of summer and continue to thrive and push out new blooms. This mounding Verbena makes a great spiller in containers as the blooms will cascade over the sides throughout the spring, summer, and fall.
The Superbena® Imperial Blue™ Verbena can be used in containers or as a groundcover while also working very well in borders, landscapes, and mass plantings. This is a versatile plant that can be used on its own or planted in combination with other plants to create a striking look. This disease-resistant plant will draw butterflies to your yard but is deer-resistant, making it a great option if you live in an area with a large deer population. This Verbena is a perennial in USDA zones 8, 9, 10, and 11.
Superbena® Imperial Blue™ Verbena Plant Care
Plant in part sun to sun, so at least 4 to 6 hours of sunlight is necessary for best results. Soil should have a pH of 5.8 to 7.2. Newly planted Verbena needs consistently damp soil, but established plants only need water when the top couple of inches of the soil dry out. Container-grown Verbena will dry out more quickly and will need water more often. Soggy conditions can lead to root rot and pests, so wait until the soil is dry to water and always opt for well-draining soil. Verbena plants are not heavy feeders, but a monthly fertilizer application will promote new growth and keep the plants healthy.
Prune the plant if it looks overgrown or tired. Verbena is a vigorous grower that can look ragged partway through the summer. Trimming back up to ⅓ of the growth can kickstart new growth and promote more branching and flowers.
Superbena® Imperial Blue™ Verbena Plant Spacing
Make sure to give this plant room to spread out because not only does it need the space, but this way, you’ll be able to appreciate the abundant blooms. This mounding Verbena can be 6 to 12 inches tall and spread out 18 to 30 inches. Leave 10 to 14 inches between plants in the ground. A container or hanging basket that measures 12 inches can handle 2 plants, and the Superbena® Imperial Blue™ Verbena can trail up to 24 inches.
