  • Position: full sun

  • Rate of growth: average to fast-growing
  • Flowering period: June to September
  • Hardiness: borderline hardy (may need winter protection)

    Tightly packed clusters of lilac-purple flowers top the tall branching stems from June to September. This stylish perennial has been enjoying a resurgence of interest in recent years. It is perfect for a sheltered, sunny spot with well-drained soil and its open, transparent shape means that it can easily be used at the front, middle or back of the border.

    This plant will help to sustain bees and butterflies into autumn with its tall wiry stems of purple flowers. It makes a good filler, because the upright stems support neighbouring plants. Plant it among the warm-red Dahlia ‘Bishop of Llandaff’ and it will act as supports, negating the need for staking, whilst providing a dazzling display.

  • Garden care: In cold conditions Verbena bonariensis can suffer dieback 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. Also it's a good idea to mulch around the base of the plant with a deep, dry mulch in winter to help protect the plant. Where the plant is grown in partial shade the stems may need to be supported - if this is necessary use natural materials such as brushwood or twiggy pea-sticks.
