How to Grow
Verbena Bonariensis seeds can be started indoors from February to June or sown outside once the risk of frost has passed. They thrive best in sunny locations with well-drained soil, making terraces, containers, and garden beds ideal planting spots.
Sowing
Scatter the seeds on firm, damp soil and pat them down gently before covering with a light layer of soil. Place the container in a sealed clear cover in a sunny position to encourage germination during the early sowing months.
Growing
Once seedlings have emerged, thin them out or pot on to a 25 cm pot size to accommodate their growth. Providing adequate spacing supports their tall, airy structure, ensuring healthy development through the growing months of June to October.
Plant care
Water Verbena Bonariensis plants regularly during establishment but reduce watering once mature, as they look after themselves well. After the first flush of blooms in spring, trim back the top quarter to promote a second flowering, and deadhead spent flowers to encourage continuous bloom and attract pollinators.
