Garden verbena

Verbena × hybrida

In other languages: Verbena (Nederlands) · Verveine hybride (Français)

Garden verbena is a summer bedding plant bred from South American species. It grows trailing to semi-upright, 20–30 cm tall and up to 40 cm wide. From June to October it carries flat, rounded heads of small flowers in red, pink, purple, blue or white, often with a white eye. Bees and butterflies love it. It enjoys sun and warmth and copes with a dry spell better than many other bedding plants, which makes it ideal for containers, hanging baskets and sunny edges.

In your garden

Why grow it?

  • Flowers from June to October if you remove the spent heads.
  • Attracts bees and butterflies, even on a balcony or patio.
  • Copes with sun, heat and some drought better than many other bedding plants.
  • Trailing forms cover a sunny edge or spill nicely from a container.
  • Colourful flower heads, often with a white eye, in red, pink, purple, blue and white.

Garden verbena: where does it grow best?

  • Full sun: the more sun, the better it flowers.
  • Free-draining soil: sand, loam or clay, acid to chalky; in pots ordinary potting compost.
  • Rather slightly too dry than too wet: it dislikes wet feet.
  • An airy spot with some space around each plant helps against mildew; plant 25–30 cm apart.

Goes well with

  • Salvia: Blue spikes beside the flat flower heads, and also a bee plant.
  • Zonal geranium: A classic pairing in sunny containers.
  • Petunia: Large trumpet flowers beside the small heads.
  • Million bells: Together they spill over the edge of a hanging basket.
  • Blue fescue: Fine blue leaves as a contrast in a sunny, dry edge.

Maintenance

Garden verbena: when and how to plant it?

Plant in May–June.

  1. Plant out from mid-May into June, once there is no more risk of night frost.
  2. Harden off home-sown plants for a week first: outside by day, inside at night.
  3. Loosen the soil and mix in some compost; in pots use potting compost and a pot with a drainage hole.
  4. Set the plants at the same depth as in their pots, 25–30 cm apart, and firm in.
  5. Water in at once; after that only in dry spells, at the base.

Care

Watering
In dry spells water at the base, ideally in the morning. A plant that dries out gets mildew more easily.
Feeding
In pots a flowering-plant feed every two weeks from June to August; in the ground, compost at planting is enough.
Deadheading
Cut off spent heads just above a pair of leaves, and it will keep making new buds.
Spacing
Do not plant too closely: airy plants stay healthier.

Tip: In the ground, give one thorough soaking rather than a little water every day: it roots more deeply and copes better with a dry summer.

Garden verbena: when to prune it?

Pruning months: July–August.

When: Remove spent flower heads all summer. In July–August you can shorten stems that are too long or bare.

How:

  • Cut off spent heads just above the next pair of leaves.
  • Shorten long, bare stems by a third to a half; the plant will branch again.
  • After trimming, water and give a little flowering-plant feed.

Pruning: when and how · Pruning calendar and basic rules

Propagation

Seed
Sow indoors in February–March at 20–25 °C. Cover the seed lightly and keep the compost moist but not wet. Germination can be slow and erratic.
Cuttings
In late August: tip cuttings of 5–8 cm from non-flowering shoots in moist cutting compost. Overwinter the rooted cuttings in a bright, frost-free place.

Garden verbena: how does it get through the winter?

Hardy to 0 °C: protect in harsh winters.

  • Not hardy: it dies in frost.
  • Treat it as an annual and sow or buy new plants each year.
  • Keep a favourite colour through cuttings, overwintered bright and frost-free at 5–10 °C.

Diseases and pests

  • Powdery mildew: A white film on the leaves, especially when the plant is dry. Water at the base in good time and remove affected leaves.
  • Aphids: On young shoots and flower buds. Spray them off with water; ladybirds help.
  • Red spider mite: Fine yellow speckling and webbing in hot, dry summers. Spray the leaves with water.
  • Root rot: On wet soil or in a pot without drainage. Plant in free-draining soil and do not overwater.

Through the year

  • February: Sow indoors at 20–25 °C.
  • March: Keep sowing. Prick out seedlings.
  • April: Grow young plants on in a light, cool place.
  • May: After mid-May, harden off and plant out in full sun.
  • June: Flowering starts. Remove spent heads.
  • July: Shorten long stems. Water in dry spells.
  • August: Take cuttings to overwinter. Feed plants in pots.
  • September: Flowering continues. Remove spent heads.
  • October: Last flowers. Clear after the first frost.
