Why Grow Verbena Bonariensis?

Few perennials offer as much impact for so little effort. Verbena bonariensis is long-flowering, low-maintenance and self-seeds gently to fill gaps in the garden year after year. Its tall, slender stems weave beautifully through other planting, and it is widely regarded as one of the finest plants for attracting butterflies to the garden. A deserving holder of the RHS Award of Garden Merit, it is a reliable and rewarding choice for gardeners of all experience levels.
