Overview

Tall branching stems carry dense clusters of violet coloured flowers throughout the summer and well into autumn. These are wonderful for adding height and structure to the border, while still maintaining a light and airy feel. Its long flowering period, statuesque habit and ability to blend into a wide range of planting styles, has made this beautiful perennial a firm favourite. 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 prop neighbouring plants. Plant it among the warm-red Dahlia 'Bishop of Llandaff' and it will offer support, negating the need for staking, whilst providing a dazzling display. Growing instructions: Early sowings can be started off in late winter in seed trays kept under glass before hardening off and planting out. Alternatively, after the worst frosts have passed, sow directly into a sunny, well-prepared seed bed, thinning the seedlings out to 45-60cm as they grow. Pinching out the growing tips will encourage bushier plants to develop. Taller plants may need supporting with brushwood stems in exposed positions. Sow: February to May Flowering: June to October

Care guide

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.
