Is Verbena a Perennial

Some perennial plants practically live forever in one place, or in one family. Will you be able to see signs of Verbena in the wild for years to come?Verbenas are long blooming annual or perennial flowers that possess the virtues of heat tolerance and an extremely long bloom season. Many perennial verbenas are relatively short lived, but their vigor and heavy flowering make up for this defect. They do well grown as annual flowering plants also, since they bloom quickly during the first season after planting.Bedding type annual verbenas raised from seed do not do well in hot, humid climates, while most of the perennial or vegetatively propagated types are well adapted to growing in South Carolina heat and humidity.

Verbena

In the fall you can trim back verbenas lightly to give a neater appearance to the garden, but do not cut severely until spring as new growth begins to appear. Overly severe fall pruning can reduce cold hardiness and plants may not survive a cold winter. Most verbenas are short-lived, so you should plan on replacing them after two or three years. However, some species can re-seed and naturalize in the garden. Purpletop Vervain (Verbena bonariensis): This 4 to 5 foot tall species is sometimes called “verbena on a stick.” Clusters of tiny lavender flowers appear above the tall, thin square stems in late spring and continue to bloom throughout the summer into fall. It is an excellent blender plant to fill in gaps in the back of the flower border, and will not crowd other plants because of its airy habit. Purpletop vervain is a short-lived perennial, but readily self-sows. It is drought tolerant. Cut plants back to encourage new blooms.

Homestead Purple’ has excellent heat tolerance, deep green foliage and is a profuse bloomer from early spring until fall frost. Plants grow up to 3 feet wide and 1 foot tall. Discovered growing on an old Georgia homestead. Verbena bonariensis is best cut down by two thirds at the end of the season to prevent wind rock and in the spring cut down further to a pair of strong shoots near the base of the plant. This will ensure good sturdy growth and the removal of apical tips around mid-May will encourage further branching, slightly shorter growth and more flowers through the season.Verbena {bonariensis} provide a bright spot of long-lasting color along borders, in cottage gardens or trailing out of containers. Several species of plants fall under the genus Verbena. Although a few of these are annuals and need to be replanted each year, many more are perennials and come back year after year. As a perennial, verbena grows well in zones 7-11, but as an annual in cooler climates and zones. (Source: homeguides.sfgate.com)
