Verbena

Verbena spp.

flower

Verbena is a vibrant flowering plant known for its clusters of small, colorful flowers that bloom prolifically throughout the growing season. It comes in annual and perennial varieties, offering a wide range of colors from purple and pink to red, white, and blue. Verbena is prized for its low maintenance, drought tolerance, and ability to attract pollinators.

Growing Conditions

☀️
Sun: Full sun, 6-8 hours daily; tolerates partial shade in hot climates
💧
Water: Moderate water needs; drought tolerant once established. Water at soil level when top inch is dry. Avoid overwatering, especially in humid conditions, to prevent mildew and root rot.
📏
Spacing: 12-18 inches
📅
Days to maturity: 60-90 days from seed to first flowers
🌱
Planting depth: Surface sow or barely cover seeds (they need light to germinate); transplants planted at same depth as nursery containers

Soil

Type: Well-draining sandy or loamy soil
pH: 6.0-7.0
Amendments:
Compost Peat moss Perlite for drainage Aged manure

Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with first true leaves appearing; very delicate and prone to damping off

Maintain consistent moisture without waterlogging; provide bright light and good air circulation; thin seedlings if overcrowded

2

Vegetative

4-6 weeks

Plant develops bushy foliage with multiple stems; leaves are typically lanceolate to ovate and slightly textured

Pinch back growing tips to encourage bushier growth; maintain moderate watering; begin fertilizing bi-weekly with diluted balanced fertilizer

3

Budding & Early Flowering

2-3 weeks

Flower buds form in dense clusters at stem tips; first blooms appear

Continue pinching if you want fuller plants, though flowering will be delayed; increase fertilizer slightly if using bloom-boosting formula; ensure consistent moisture

4

Full Flowering

8-12 weeks (or until frost for annuals)

Plant covered with vibrant flower clusters; blooms densely packed and colorful

Deadhead spent flowers to encourage continuous blooming; reduce nitrogen fertilizer to promote more flowers; water deeply but infrequently; watch for mildew in humid conditions

5

Seed Development & Decline

Variable, extends through fall

If not deadheaded, flowers fade and develop seed capsules; plant growth slows

Allow some flowers to set seed if you want self-seeding or to collect seed; stop fertilizing; reduce watering gradually; prepare for end of season (annuals) or dormancy (perennials)

Common Pests

  • Improve air circulation; avoid overhead watering; apply sulfur dust or neem oil; remove affected leaves; choose mildew-resistant varieties

  • Spray with strong water stream; increase humidity; apply neem oil or insecticidal soap; ensure adequate moisture in soil

  • Use yellow sticky traps; spray with insecticidal soap; apply neem oil; remove heavily infested plant parts

  • Remove affected leaves; reduce nitrogen fertilizer; encourage natural predators; apply neem oil if severe

  • and

    Hand-pick early morning or evening; use beer traps; apply diatomaceous earth; encourage predatory beetles

Harvest Tips

Verbena is primarily ornamental and not harvested for crops. For seed collection: allow flowers to dry on plant, then cut seed heads and dry indoors in paper bags. For cutting flowers: harvest in early morning when stems are turgid; cut just above a leaf node to encourage branching. Flowers last about 5-7 days in a vase with fresh water.

Fun Facts

  • 🌱 Verbena was sacred to ancient Romans and Greeks, who used it in religious ceremonies and believed it had protective and purifying powers.
  • 🌱 Some verbena varieties, like lemon verbena (Aloysia citrodora), have fragrant foliage that releases a pleasant scent when brushed or touched—making them popular for sensory gardens.
  • 🌱 Verbena can self-seed readily, returning year after year in garden beds and serving as a reliable perennial or annual volunteer depending on your climate zone.
