These lively and colourful annual plants have small bright green to bluish-green leaves. Clusters of small flowers in dazzling shades of white, pink, red, purple and blue appear over a long period during the hottest months. Verbena produces flower stalks that continue to grow up, producing more buds from the centre. The result is a continuously blooming circle of flowers.
There are many varieties, including: Verbena “Homestead Purple”, a hardy, trailing ground cover with dazzling, rich purple flowerheads; Dwarf Verbena, a sensational ground cover with fragrant bright blooms over many months; Verbena “Peaches and Cream” with pink, peach and white flowers. New varieties are constantly being developed and added to the range.
The hardy verbena is great mass-planted as a ground cover or border plant in a sunny garden. It also looks striking in a pot or a hanging basket. Some varieties have a trailing habit, while others are more upright. Verbena is a fantastic plant for attracting beneficial insects to your garden. Butterflies love it! There’s sure to be a variety of this hardy little plant that suits your garden.
Annual verbenas are generally propagated from seed in trays filled with a good-quality seed-raising mix. You’ll find a great range of verbena seeds in store.
Although verbena is tough and drought-resistant, a regular deep watering once a week in summer will improve flowering. Take care not to wet the foliage. Using a good-quality, controlled-release fertiliser in spring and again after trimming will help keep your plant strong and healthy, producing plenty of colourful flowers.
Powdery mildew is the most common disease affecting this otherwise hardy little plant. Often this is caused by overcrowding, overhead watering and humidity. Treat it with an organic fungicide and be sure to clean up any dead leaves or stems around the plant to help prevent reinfection.
Watch out for snails and slugs, particularly after rain. Snail traps are a great safe solution, or if you’re a coffee drinker, save your coffee grounds and sprinkle them around the plant as a barrier to keep them from feasting on your precious plants.
