The genus offers a range of plant sizes and flower colours, from white to deep purple. Verbenas are deciduous, so will die back over the winter months and regrow the following spring.In summary, verbena is an attractive, long-blooming, and low-maintenance plant that supports pollinators and thrives in various garden settings.

Does verbena spread quickly?
Does verbena spread? Yes, many types of verbena spread, especially low-growing or trailing varieties, which can spread 18 to 25 inches in a single growing season. While verbena can be vigorous, it’s not considered to be invasive. Most varieties do, as they are perennials. They are herbaceous, so the tops will usually die back, re-emerging in the spring. Once these new shoots appear, the brown stems from last year can be cut back to ground level, usually in about March. Annual types of Verbena will not come back again.Annual Verbena plants can be cut back in the fall. Perennial Verbena will grow year-round in subtropical climates. In this type of environment, it is only necessary to trim back dead growth as it occurs. In most other regions, perennial Verbenas will need to overwinter.Verbena can be deadheaded throughout the flowering period, but it is best to wait until spring for a major cut back. Leave the seed heads in place to provide cover for wildlife and food for the birds, then once new growth begins to shoot from the base, cut back the old woody growth from the previous year.Propagating Verbena Take stem cuttings in late summer or early fall. Remove the bottom pair of leaves right at the stem. Dip the bottom of the stem in rooting hormone and plant about 1 inch deep in a container with moist potting soil. Place the container on a sunny windowsill to root.After the big flush of spring flowers you can do two to three periodic trimmings per summer, trimming your verbena’s branches/stems back by about one-fourth their length. Doing so encourages new growth and flowers. If plants look a little weak or like they could use a boost apply aflower fertilizer.
