Creating a stunning garden display with vibrant colors can be a delightful and fulfilling endeavor. One of the easiest and most rewarding plants to include in your garden is verbena. Known for its ability to thrive in various conditions and produce abundant blooms, verbena is a favorite among gardeners. This article will guide you through the process of growing verbena from seeds and how to create a mesmerizing garden display.

Understanding Verbena

What is Verbena?

Verbena is a genus of flowering plants in the Verbenaceae family, with over 250 species. These hardy perennials and annuals are prized for their prolific blooms and aromatic foliage. Verbena comes in a variety of colors, including purple, pink, red, and white. Its flowers can attract pollinators like bees and butterflies, making it a fantastic addition to any garden.

Varieties of Verbena

There are several types of verbena you can grow from seeds. Some popular varieties include:

• Trailing Verbena (Verbena canadensis): Ideal for hanging baskets and containers, with a cascading growth habit.
• Garden Verbena (Verbena x hybrida): Known for its vibrant blooms and adaptable nature, perfect for adding color to borders.
• Lemon Verbena (Aloysia citrodora): Though primarily grown for its leaves, which have a strong lemon scent, it can also produce small purple flowers.

• Seed trays or biodegradable pots
• Seed starting mix
• Watering can or spray bottle
• Labels for identifying varieties
• A clear plastic cover or plastic wrap (optional)

Step 2: Start Seeds Indoors

Growing verbena from seeds typically begins indoors, particularly in cool climates.

1. Timing: Start your seeds 8-10 weeks before the last expected frost date. Check your local extension service for specific dates.

2. Fill Containers: Fill your seed trays or pots with a light seed starting mix. Moisten the mix lightly to ensure it’s damp but not soggy.

3. Sow Seeds: Scatter verbena seeds on the surface of the soil, aiming for a spacing of about 1 inch apart. Lightly press them into the soil or cover them with a thin layer of soil mix, as they require light to germinate.

4. Label: Use labels to indicate the variety and date of planting.

Step 3: Create the Right Environment

1. Light: Verbena seeds need plenty of light for germination. Place your trays in a sunny window or under grow lights. Ensure they receive 12-16 hours of light daily.

2. Temperature: Maintain a temperature of 70-75°F (21-24°C) for optimal germination. If your home is cooler, consider using a seedling heat mat.

3. Humidity: Covering the trays with a clear plastic cover can help maintain humidity until germination occurs. Remove the cover once the seeds sprout.

Step 4: Watering

Keep the soil consistently moist but not oversaturated. Using a spray bottle can help prevent disturbing the seeds. Water carefully from below by placing the trays in shallow water and letting the soil absorb moisture.

Step 5: Thin Seedlings

Once your seedlings develop their first true leaves, thin them out to avoid competition for nutrients. This usually means selecting the healthiest seedlings to keep and removing the weaker ones. Aim to provide each remaining seedling with at least 3 inches of space.

Step 6: Transplanting

1. Harden Off: About 1-2 weeks before transplanting outdoors, start hardening off your seedlings by gradually exposing them to outdoor conditions. Begin with a few hours in a shaded area, slowly increasing their time outside over several days.

2. Select a Planting Location: Verbena prefers full sun (at least 6-8 hours of sunlight daily) and well-draining soil. It can thrive in various soil types but benefits from soil rich in organic matter.

3. Transplanting: After the last frost date, transplant your seedlings into prepared garden beds or containers. Space them about 12-18 inches apart to allow for growth. Water well after transplanting.

Creating a Colorful Garden Display

Design Principles

When arranging verbena in your garden, consider the following design principles:

1. Color Harmony: Use a color wheel to choose complementary colors that will create a harmonious display. Mixing different verbena species can add variety and intrigue to your garden.

2. Height Variation: Combine verbena with plants of varying heights to create visual interest. Taller plants can serve as a backdrop, while verbena can fill in front spaces.

3. Texture and Form: Incorporate plants with different textures and forms alongside verbena. Plants with broad leaves or spiky blooms can enhance the overall aesthetic.

Companion Planting

Verbena pairs well with several other plants, including:

• Petunias: Bright and cheerful, petunias can complement verbena’s flowers beautifully.
• Marigolds: Their vibrant orange and yellow hues provide a striking contrast.
• Salvia: This hardy perennial can add height and structure to your garden while attracting pollinators.

Arrangement Ideas

1. Borders: Plant verbena along pathways or garden borders for a colorful edge.

2. Containers: Create stunning container displays by combining verbena with other annuals and perennials. Use trailing verbena in hanging baskets for a cascading effect.

3. Mixed Beds: Plant verbena in mixed flower beds alongside other perennials and annuals to create a diverse landscape.

Maintenance

1. Watering: Verbena is drought-tolerant once established but requires regular watering during dry spells, especially for young plants.

2. Deadheading: Remove spent blooms to encourage more flowering, thereby extending your verbena’s blooming period.

3. Fertilizing: While verbena doesn’t require excessive fertilization, a balanced, slow-release fertilizer in early spring can promote healthy growth.

4. Pest Control: Keep an eye out for aphids and other pests. Using insecticidal soap or neem oil can be effective in managing pest populations.
