What is Verbena?
Verbena (Verbena hybrida) is a herbaceous trailing perennial. It is part of the Verbenaceae family which contains 250 species of annuals and perennials where the majority are native to the Americas and Asia. Verbena has a sprawling or spreading habit with erect stems. They have small dark to bright green foliage that are slightly hairy depending on the variety. The leaves mainly form on the lower half of the stem which allows the flowers to form at the tips. Compact clusters of flowers will form during early Summer through to early Autumn producing a mass of colour. The flowers typically come in vibrant shades of purple, pink, red, and white, and often flower prolifically over a long season. Some varieties have fragrant flowers. They prefer full sun in cooler regions to semi shade in warmer climates where most varieties are both heat and cold tolerant.

Verbena Plant Care
Water freely during the growing season but sparingly during Winter as water logging can kill the roots. They can withstand dry periods.
Fertilise annually in Spring with a long term slow release fertiliser.
Pinch out new shoots to promote bushy growth. Remove dead flower heads to encourage flowering.
Watch out for aphids and snails. Powdery mildew can also be a problem.
They do self-seed easily so be aware if you don’t want them spreading. Removing the flower heads before they drop their seed will prevent this.
