One of the most fuss-free flowering plants, verbenas require little care in the garden. Plant them in containers, hanging baskets and in the ground. Trailing types look good in rock gardens and cascade over short retaining walls.
verbena
Whether used as a container plant or in garden beds, verbena plants offer endless color, from the first warm whispers of spring through the frosty gloom of fall. Its lush, long blooming season outshines many other flowers, ensuring your gardens are always covered in cheerful hues.
Verbenas are easy to grow, especially in sunny or partially shady spots. They do best in well-draining soil, and they tolerate heat and drought. They also attract butterflies and other pollinators, making them a valuable addition to your garden.
A wide variety of verbenas are available, ranging from trailing groundcover to upright perennials and shrubs. Some examples include ‘Greystone Daphne’ with pinkish lavender flowers, ‘Homestead Purple’ with deep violet flowers and ‘Snowflurry’ with white flower clusters.
The flowers and leaves of verbenas are often used to impart a lemon flavor to desserts, baked goods and tea. Early research has found that the essential oils of some varieties, particularly lemon verbena (Aloysia citrodora), have anticonvulsant and anxiolytic properties, and may also act as a mild sedative. However, further advance molecular studies are required to validate these claims.

VERBENA CARE
The bright flowers of verbena make it a beautiful addition to the landscape. These easy-to-grow flowers are suitable for a wide range of climates, and most varieties can be grown as either perennials or annuals. They can also be used in containers. Annuals need to be replaced each year, but perennials often reseed themselves and can come back year after year.
In the garden, verbena tolerates most soil types, though they do best in rich, well-draining soil. It can even thrive in sandy soils, which may benefit from the addition of compost or fertilizer. When growing in containers, use a well-draining potting mix.
Verbena plants have few problems with pests and disease, but if you see signs of stress, such as leggy growth or sparse flowering, it could be due to lack of sunlight or poorly drained soil. Move the plants to a sunnier location, and give them a good watering.
If your verbena plants are not thriving, consider propagating them from 3-inch cuttings taken in late spring. Remove all but the top one or two sets of leaves, dip them in rooting hormone, and plant them in a pot of moist, loose, well-draining planting medium. Put the pot inside a plastic bag, and keep it in a warm, sunny location for about six weeks.
TROUBLESHOOTING VERBENA
One of the easiest flowers you can plant Verbena has a minor diseases or pests. When problems do arise it is mostly due to lack of sunlight or a poorly-drained soil. Here are a few stress indicators to look out for and possible solutions.
Spider mites are among the few pests that cause an issue. If you see netting that resembles spider webs on your plants, and leaves are discolored, spray leaves with a powerful stream of water, or using the insecticide soap. Beware of chemical insecticides that could cause harm to pollinators. See: How to Control Spider Mites
The sagging plants and the sparse flowers usually result from too much shade. Transfer them to a place in your garden where they receive 6 or more hours of sunlight. Verbenas can recover quickly when transplanted, and so do not be afraid to move your plants into the best location.
The mildew that is powdery is the largest and most prevalent issue. Make sure your plants have enough space for air circulation and to avoid watering the overhead. Don’t water your plants in the evening so that the foliage isn’t damp all night. See: How to Get Rid of Powdery Mildew.
Leaves that are yellow, insufficient flowering and root Rot are all indicators that your drainage is poor. It is possible to keep your plants alive by moving them to an area with better drainage or raised beds. If you have plants that are grown in containers make sure you have drainage holes.
