Supplied as 6 x plug plants ready for potting up and growing on before planting out.
Leave faded flower heads on the plant over winter, to provide structure in the garden as well as shelter for hibernating insects.
Grow in well-drained, moderately fertile soil in full sun. In cold areas, protect with a dry winter mulch.
Verbena bonariensis can suffer dieback in harsh winters if cut back in autumn, so it's best to leave the plant until spring and cut back the old growth when you see the new shoots emerging at the base.
