Verbena: Everything You Need to Know About Planting and Care
How to plant verbena
Verbena are sun lovers and should be planted in full sun (that’s at least six hours of direct sunlight each day) in plant hardiness zones 5–9, though exact growing zone will depend on the variety. With less than full sun, verbena will struggle.
Verbena thrives in a variety of soil conditions and don’t require much water, especially once established, but you will want to make sure the soil drains well. Additionally, avoid planting your verbena too closely together in order to keep them healthy and precent the spread of mildew.
How to care for verbena
- Verbena are fairly easy to care for and will thrive as long as they get plenty of sunlight and about an inch or so of water each week.
- Mildew is likely the biggest issue you’ll encounter when planting and caring for verbena. You’ll know it’s present if you notice a white, powder-like residue on the plant. As mentioned above, one way to avoid the spread of mildew is to leave space between verbena when planting so they have room to air out and so that mildew isn’t able to easily spread from plant to plant. When planted in soil that doesn’t drain well, root rot can also be an issue.
- Additionally, you’ll want to remove dead plants and debris from the garden or planter boxes as necessary, and remove dead flower heads to keep the plants healthy and encourage future blooms. If you happen to have an issue with insects, remember that spraying will likely have a negative impact on butterflies, which are attracted to this sprawling bloom, so non-chemical methods of pest control are best.
Groundcover Verbena Varieties – Can You Use Verbena For Groundcover
Verbena plants come in a variety of shapes and sizes. While some have an upright growing pattern, there are several that stay very short and spread quickly by creeping along the ground. These varieties are great for groundcover, and will fill in an empty space very fast with delicate, low foliage and bright flowers. Keep reading to learn more about growing creeping verbena plants and using verbena as groundcover.
How to Use Verbena for Groundcover
While some verbena varieties grow as bushes that can reach 4 to 5 feet (1.2-1.5 m.) in height, there are plenty of other varieties that stay low to the ground. Some are trailing plants that spread along the ground. They put out creeping stems that root themselves easily in the ground and establish new plants.
Others are just low growing, upright plants that top out at about
1 foot (30 cm.) high. These plants spread out via rhizomes underground that put up new shoots nearby. Both of these styles are very low growing and fast spreading and are great options for groundcover.
When opting to use these plants for ground coverage in the garden, plant them in triangular groups with about 12-inch (30 cm.) spacing between them. Of course, this will vary depending on the available garden space, so take this into consideration. Knowing the total square footage can help determine the amount of plants needed to fill the area, along with their spacing.
Popular Groundcover Verbena Varieties
Here are a few common groundcover verbena plants:
Trailing Verbena – Formerly called Verbena canadensis but now known as Glandularia canadensis, these creeping verbena plants make up a broad group that serves very well as groundcover. Some popular cultivars are “Summer Blaze,” “Snowflurry,” “Greystone Daphne,” and “Appleblossom.”
Rigid Verbena – Native to South America, these verbena plants spread quickly by underground rhizomes. They are very hardy and drought resistant. Some popular cultivars include “Polaris” and “Santos.”
Prairie Verbena – Reaching only 3 to 6 inches (7.5-15 cm.) in height, this plant produces vivid, deep purple flowers.
Peruvian Verbena – Under a foot tall, these plants produce pink to white flowers that bloom all summer long.
Goodings Verbena – These plants produce lots of lavender flowers in the spring. They need full sun and lots of water.
Sandpaper Verbena – Producing deep purple flowers in the spring, these plants self-sow and spread by seed very quickly and run the risk of becoming invasive.
Verbena is the ideal plant to cascade over retaining walls, containers, baskets, and window boxes. As long as its soil is well drained, verbena will reward gardeners with countless clusters blooms all season long. Verbena is also drought tolerant, making it a great choice for rock gardens and for planting in cracks between stones.
The more common verbenas are generally a hybrid of many different species to make the common varieties you see today. However, there is another commonly planted verbena, Verbena bonariensis. V. bonariensis or purpletop vervain, is a wonderfully versatile annual. Unlike the more common verbena, the purpletop vervain is very tall. These plants can get up to three to four feet tall. They make a great show in a garden setting, especially with other prairie type plants and grasses. The flowers of the purpletop vervain are much smaller than the more common verbena, but just as plentiful.

Flowers of verbena are held in continuously blooming circles atop the tips of all of the stems. These bloom stalks just keep blooming all season long and continue to grow up, producing new buds all the time. This also eliminates the need for dead-heading, as they continue to bloom on top of wilted flowers. Petals on the blooms of verbena can be quite varied, with fringed edges, stripes, white eyes, and even streaks of color.
Annual verbena makes a great accent in containers and has a couple of options. Some varieties are more of a trailing habit and are great spilling out of containers or in large groupings as a groundcover. Other varieties are more upright and a good option for smaller spaces and smaller containers.
Verbena Care Must-Knows
As far as problems go, verbenas are pretty free of disease. The biggest concern is mildew. This shows up on the plants as a powdery white residue on the leaves, and eventually causes the plant to slowly decline in vigor. Generally it will not kill a plant, but will stress it some and slow it down. This is a common problem with the purpletop vervain, especially on lower growth. The best solution for powdery mildew is to plant the plants in a well circulated area, making sure the plants leaves dry out well after a rain or watering. If this has been a problem in the garden in the past, make sure to clean up any old plant debris like dead leaves or stems on the ground. Cleaning up old material is the best prevention and rotating plantings so the same susceptible plants aren’t in the same spot each year.

If you’re interesting in growing annual verbena in your gardens or containers, they can easily be started from seed. The tall purpletop vervain will even re-seed itself year after year, if left undisturbed.

The pale and dark blues of larkspur are some of the prettiest you’ll find in the garden. And they come with little effort. Plant larkspur once and allow the flower heads to ripen, scattering their seed, and you’ll be assured of a steady supply of larkspur in your garden for decades. All you’ll need to do is pull out the ones you don’t want!Larkspur is basically an annual version of delphinium, an all-time favorite perennial. Larkspur produces lovely spikes of blue, purple, pink, or white flowers in spring and summer. They look best clustered in small patches.Like many cool-season annuals, it’s a good winter-blooming plant for the Deep South. Larkspur is so easy to grow that it often self seeds in the garden, coming back year after year. Plant larkspur from seed directly in the garden in early spring. Larkspur doesn’t like to be transplanted. It prefers rich, well-drained soil and ample water.When hot weather strikes and larkspur starts to brown and fade, pull out plants, but be sure to leave a few to brown and reseed.
Petunias are failproof favorites for gardeners everywhere. They are vigorous growers and prolific bloomers from midspring through late fall. Color choices are nearly limitless, with some sporting beautiful veining and intriguing colors. Many varieties are sweetly fragrant (sniff blooms in the garden center to be sure.) Some also tout themselves as “weatherproof,” which means that the flowers don’t close up when water is splashed on them.Wave petunias have made this plant even more popular. Reaching up to 4 feet long, it’s great as a groundcover or when cascading from window boxes and pots. All petunias do best and grow more bushy and full if you pinch or cut them back by one- to two-thirds in midsummer.Shown above: Merlin Blue Morn petunia
Few gardens should be without the easy charm of snapdragons. They get their name from the fact that you can gently squeeze the sides of the intricately shaped flower and see the jaws of a dragon head snap closed. The blooms come in gorgeous colors, including some with beautiful color variations on each flower. Plus, snapdragons are an outstanding cut flower. Gather a dozen or more in a small vase and you’ll have one of the prettiest bouquets around.Snapdragons are especially useful because they’re a cool-season annual, coming into their own in early spring when the warm-season annuals, such as marigolds and impatiens, are just being planted. They’re also great for fall color.Plant snapdragon in early spring, a few weeks before your region’s last frost date. Deadhead regularly for best bloom and fertilize regularly. Snapdragons often self-seed in the landscape if not deadheaded, so they come back year after year, though the colors from hybrid plants will often will be muddy looking. In mild regions, the entire plant may overwinter if covered with mulch.Shown above: ‘Rocket Red’ snapdragon
