Verbena supina: complete guide

Overview

Verbena supina, commonly known as trailing verbena or procumbent vervain, is a charming, low-growing plant in the Verbenaceae family. This Mediterranean species is known for its delicate, spreading growth habit and abundant, fine white flowers. The plant typically reaches 20-30 cm in height and spreads to about 40 cm, making it ideal for borders, rock gardens, and as groundcover.

Native to South and Southeast Europe extending to India, in temperate climates Verbena supina is a valuable addition to gardens where soft, elegant texture is desired.

Appearance & bloom

Verbena supina features fine, narrow leaves arranged in opposite pairs along thin, much-branched stems. The leaves are narrowly lanceolate and usually glabrous to finely pubescent. The plant is chiefly valued for its many small, white flowers appearing throughout the summer months.

Flowers develop in small, dense inflorescences at the stem ends. They are very small but abundant, allowing the plant to flower from May through October. This extended blooming pattern makes Verbena supina exceptionally valuable in gardens.

Ideal location

Verbena supina grows best in a location with full sun, receiving at least 6 hours of direct sunlight daily. The plant tolerates partial shade but flowers more profusely in full sun. Plant where the specimen can dry well after rain.

Soil

The plant is not demanding regarding soil, as long as it drains well. Heavy clay soils should be improved with sand or compost. A slightly acidic to neutral soil (pH 6-7) is preferred. Avoid wet feet in winter.

Watering

Once established, Verbena supina is quite drought-tolerant. Water regularly during the growing season, especially during dry periods. Avoid watering after rain. In winter, watering can be greatly reduced. Ensure the soil dries between waterings.

Pruning

Pruning is not essential, but light pinching during the growing season helps keep the plant more compact. After blooming, lightly cut back the plant for a rounder, fuller appearance.

Maintenance calendar

Spring (March-May): Begin watering as temperatures rise. Apply a thin layer of compost around the plant for nutrition. Ensure old foliage and stems are removed. Summer (June-August): Water during dry periods. Remove spent flowers for extended blooming. Check for pests. Autumn (September-October): Reduce watering as temperatures fall. Blooming typically continues through October. Winter (November-February): Minimal care. Protect against intense frost periods. Pruning can be done in spring.

Winter hardiness

Verbena supina is moderately winter-hardy and can tolerate temperatures down to approximately -5 C. In colder climates, it is better grown as an annual or protected from frost. In milder climates it can overwinter outdoors if sited in a well-draining location.

Companion plants

Verbena supina combines beautifully with:

• Rosemary (Rosmarinus officinalis)
• Lavender (Lavandula angustifolia)
• Coneflower (Echinacea)
• Phlox (Phlox)
• Sunflower (Helianthus)

Closing
