Verbena plants are a favorite addition to many landscapes, due to their tendency to be heat- and drought-tolerant and their long blooming season. These sun-loving beauties come in just about any color. They can be annuals or perennials, depending on the type of flower and the climate where they are grown.
Moss verbena are native to South America and thrive in hot weather when given plenty of water and fertilizer. They are somewhat drought-tolerant, but flowering and growth will not be as vigorous during dry times. Moss verbena have fine, cut leaves and grow low to the ground. They can be found in many shades of purples, pinks, corals and blues. Sissinghurst, Imagination, Sterling Star and Edith are popular cultivars of moss verbena.
Annual verbena are found commonly in home garden beds with clusters of star-shaped blooms on the ends of their branches. Annual verbena grow well in full sun in well-drained soils, but they will bloom less in the hottest parts of summer. You can find annual verbena in a variety of colors, such as red, white, peach and salmon. Types of annual verbena include the Obsession series, Peaches and Cream and the Romance series.
Trailing or Clump Verbena
Trailing or clump verbena are a low, spreading form of verbena that will flower all summer long. It is heat- and drought-tolerant but will perform best when given enough water and fertilizer in well-drained soil. Blooms can be found in many colors, including purple, red, pink and white. Popular types are Silver Anne, Snowflurry, Taylortown Red and Homestead Purple.
Rigid verbena blooms in clusters of purple or magenta. Plant it in full sun in a moist, well-drained soil. It is heat- and drought-resistant and will bloom from June to September. Low spreading rigid verbena makes a good groundcover and is very effective at attracting bees and butterflies.
Brazilian verbena can reach heights of 4 or 5 feet. This drought-tolerant perennial has clusters of lavender flowers on the tops of its tall stems. It blooms from spring until fall and works well in flower borders.
