How to grow Verbena

Verbena bonariensis

If verbena plants get leggy, simply trim the stems with sharp scissors. Cutting back prompts repeat flowering.

Growing Verbena from seed

This plant readily self-seeds, and can quickly grow out of control in an area. Prevent this by dead heading constantly from blooming, to when the plant dies down/goes dormant.
Easy to germinate, pot up individually when leaves are large enough to handle.

Look to ensure a distance 1.24 feet (38.0 cm) between seeds when sowing - bury at a depth of at least 0.2 inches (0.5 cm) deep. Soil temperature should be kept higher than 12°C / 54°F to ensure good germination.

By our calculations*, you should look at sowing Verbena about 49 days before your last frost date .

Transplanting Verbena

Using a trowel dig holes 10 in. apart and as deep as the flat. Add water to the holes. Water plants in flat and remove with trowel. Loosen any matted roots on plants and set in holes at the same level they grew in the flat. Firm soil to eliminate air pockets. Water entire area using a hose with a nozzle. Water deeply, but keep blooming plants on the dry side rather than wet.

Choose a place towards the back of the border as the stems are very tall.1 Also nice as a ‘see through’ plant between walkways.1

Ensure that temperatures are mild (minimum night temperatures should be around -15°C / 5°F) and all chance of frost has passed before planting out, as Verbena is a half hardy plant.
