Description
The Sunswept brings a blazing display of yellow, orange, and reddish brown from July to September into perennial beds. Its basket-shaped flowers with a convex central disk are a magnet for bees and butterflies, especially when other perennials have already faded. Depending on the variety it grows 80 to 140 cm tall and requires a sunny, not too dry spot.
Care instructions
Plant it in fertile, fresh soil in full sun and water regularly during dry periods; it does not like dried-out roots. In May cut the shoots back by one third once, which keeps the clump sturdy and encourages bushier flowering. Divide the plant every three to four years in spring to keep it young and flowering. Regularly remove spent flowers to extend the bloom into autumn.
