A tall and slender-stemmed perennial. It can grow to 180 cm tall and can spread to 90cm wide. At maturity, it will develop a woody base. Fragrant lavender to rose-purple flowers are in tight clusters located on terminal and axillary stems, blooming from mid-summer until autumn frost. It’s perfect for bringing height to an ornamental border and also works well in prairie-style planting schemes with ornamental grasses. Verbena bonariensis will self-seed freely and naturalise in borders. Grow Verbena bonariensis in moist but well-drained soil in full sun. Leave dead stalks to provide winter interest and mulch annually with well-rotted manure or compost.

Verbena seeds can be sown directly into the garden or seedlings can in containers and transplanted to the garden once established. Sprinkle seeds on top of soil and water. Kepp damp but not wet. Seeds should germinate in around 20-25 days at a soil temperature of 21-24C.
Also known as Purpletop vervain.
