Verbena bonariensis is one of the most popular and elegant garden perennials, prized for its tall, wiry stems topped with clusters of small, vibrant purple flowers. This stunning plant creates a wonderful see-through effect in borders and mixed plantings, adding height and movement without blocking the view of plants behind. A magnet for bees, butterflies and other pollinators, it is an essential addition to any wildlife-friendly garden.

Supplied as a set of three established plants in 1 litre root-balls, ready for planting straight into borders, beds or large containers. Verbena bonariensis is a reliable, low-maintenance perennial that often self-seeds gently, rewarding you with new plants year after year.
