What Is Verbena Bonariensis?
Verbena is a genus of flowering plants that includes over 250 species. Most varieties produce vibrant clusters of flowers that come in colors such as purple, pink, white, and red. Native to the Americas and Europe, verbena has been historically used in traditional medicine, often valued for its supposed healing and calming properties. Today, verbena is appreciated both for its visual appeal and its potential health benefits.
Types of Verbena
Verbena Officinalis (Common Vervain): This species is best known for its medicinal properties and subtle lavender flowers. It has a long history in herbal medicine and is often used in teas or supplements for its calming effects.
Verbena Bonariensis (Purpletop Vervain): Tall and elegant, this variety produces clusters of purple flowers that attract bees and butterflies. Its height makes it a striking addition to any garden.
Trailing Verbena: Known for its cascading growth, trailing verbena is a favorite in hanging baskets and borders. It blooms in various colors and adds a pop of color to garden arrangements.
Garden Verbena: This type is popular in home gardens and is known for its resilience and vibrant flowers, which bloom throughout the summer and into the fall.
Planting and Growing Verbena
Ideal Growing Conditions
Light: Verbena thrives in full sun, needing at least six to eight hours of sunlight daily.
Soil: Verbena prefers well-draining soil with moderate fertility. Amending soil with compost can help improve its health.
Water: Though verbena is drought-tolerant, it should be watered regularly when first planted. Once established, it requires only occasional watering, especially during dry spells.
Planting Tips
Timing: The best time to plant verbena is in the spring after the last frost. This gives it time to establish roots before the hot summer months.
Spacing: Space the plants 12–18 inches apart to allow room for growth and airflow, which helps prevent disease.
Mulching: Applying a layer of mulch can help retain soil moisture and suppress weeds.
Maintenance and Care
Pruning: Regular deadheading encourages prolonged blooming. In late summer, trimming back leggy stems can lead to a fresh bloom in the fall.
Fertilizing: Verbena benefits from a balanced fertilizer applied in spring and mid-summer. Avoid over-fertilizing, which can lead to more foliage and fewer flowers.
Pest and Disease Management: Verbena is relatively pest-resistant but can be susceptible to powdery mildew in humid climates. Ensuring good airflow and avoiding overhead watering can help prevent this.
Health Benefits of Verbena
Verbena has been traditionally used in herbal medicine for various ailments. Here are some of the potential health benefits attributed to verbena, particularly Verbena officinalis:
Antioxidant Properties: Verbena is rich in antioxidants, which help combat oxidative stress and may protect cells from damage.
Anti-inflammatory Effects: Verbena may help reduce inflammation, which is beneficial for those with arthritis or inflammatory conditions.
Calming and Sedative Properties: Verbena officinalis is often used in teas to promote relaxation, reduce anxiety, and aid sleep.
Digestive Health: Verbena is thought to have a mild laxative effect, which can help ease constipation. It’s also used to soothe stomach discomfort.
Immune Support: Due to its antiviral and antimicrobial properties, verbena may support immune health and assist in fighting off colds and infections.
How to Use Verbena
Herbal Tea: Verbena tea is one of the most popular ways to enjoy its health benefits. Simply steep dried verbena leaves in hot water for 5–10 minutes.
Essential Oil: Verbena essential oil, known for its fresh and lemony scent, is used in aromatherapy to reduce stress and uplift mood.
Topical Application: Verbena extracts are sometimes used in creams and ointments to relieve sore muscles and joint pain.

Common Issues When Growing Verbena
Powdery Mildew: This fungal disease appears as white powder on the leaves, usually due to high humidity and poor air circulation.
