Understanding the Verbena Plant

Here’s a short information chart about verbena:

Verbena is a diverse genus of plants that includes both annual and perennial varieties. Annual verbenas, such as the popular Verbena x hybrida, are prized for their prolific blooms and are often grown as bedding plants or in containers. Perennial verbenas, like the hardy Verbena bonariensis, are valued for their long-lasting displays and ability to naturalize in the garden.

Popular Varieties

With their wide range of colors, growth habits, and bloom forms, verbenas offer something for every gardener’s taste and planting need. Some popular varieties include:

• Lanai® Series: Compact, mounded plants with large, vibrant flower clusters.
• Tapien® Series: Trailing verbenas perfect for hanging baskets and containers.
• Endurascape™ Series: Heat and drought-tolerant varieties ideal for low-maintenance gardens.
• Bonariensis: A tall, perennial verbena with striking purple blooms and airy foliage.

Planting and Care

Choosing the Right Location

Verbenas thrive in full sun, requiring at least six hours of direct sunlight per day. They also prefer well-draining soil, as their roots can easily rot in overly moist conditions.

Soil Preparation

Before planting, amend the soil with compost or well-rotted manure to improve drainage and fertility. Verbenas prefer a slightly alkaline soil pH between 6.5 and 7.5.

Planting Techniques

For annual verbenas, plant them after the last frost date in your area, spacing them 8 to 12 inches apart. Perennial verbenas can be planted in early spring or fall, with a spacing of 18 to 24 inches.

Watering and Fertilizing

Verbenas have moderate water needs, requiring regular watering to keep the soil consistently moist but not waterlogged. Apply a balanced, water-soluble fertilizer every four to six weeks during the growing season for optimal bloom production.

Pruning and Deadheading

Regular deadheading, or removing spent flowers, will encourage verbenas to continue blooming prolifically. Pinching back the plants occasionally will also help promote a fuller, bushier growth habit.

Overwintering

Perennial Verbenas In colder climates, perennial verbenas may need to be protected or brought indoors during the winter months. Mulch around the base of the plants and consider covering them with a cold frame or burlap wrap when temperatures drop.

Designing with Verbena

Container Gardens

Verbenas are a fantastic choice for container gardening, spilling over the edges of pots and hanging baskets with their vibrant blooms and trailing stems.

Garden Beds and Borders

Incorporate verbenas into garden beds and borders for a stunning display of continuous color. Their mounded or trailing growth habits make them excellent edging plants or ground covers.

Companion Planting

Verbenas pair beautifully with a variety of other sun-loving annuals and perennials. Try combining them with upright plants like salvia, coreopsis, or ornamental grasses for a visually striking contrast in texture and form.

Cut Flowers

While not traditionally grown as cut flowers, verbena blooms can be used in fresh or dried arrangements for a whimsical, informal touch.

Troubleshooting Common Issues

Pests and Diseases

Verbenas are generally quite resistant to pests and diseases, but keep an eye out for common issues such as aphids, spider mites, and powdery mildew. Proper watering, spacing, and air circulation can help prevent many problems.

Fading Blooms

If your verbena blooms start to fade or become washed out, it could be a sign of too much direct sunlight or heat stress. Providing afternoon shade or increasing water during hot spells can help revive the plants.

Leggy Growth

If your verbena plants become leggy or straggly, it’s likely due to insufficient sunlight or overcrowding. Prune them back and move them to a sunnier location or thin out the plants for better air circulation.

Verbena is a true showstopper in the garden, offering a vibrant and long-lasting display of color that will brighten any outdoor space from spring until frost.
