Coneflower Herbstsonne The name means ‘Autumn Sun’, perfect for the yellow-rayed flowers of Rudbeckia laciniata Herbstsonne. It’s a tall, imposing, clump-forming, herbaceous perennial which grows up to 6’6”/2m tall, ideal in drifts at the back of a large border or beside a pond. The leaves are divided, and mid-green. In August and September, and often into October, large, single, citrus-yellow flowers are borne singly at the top of the branching stems; the slightly drooping, ray florets (petals) surround a bright-green cone of fertile florets. The flowers are good for cutting, and are very attractive to butterflies. The conical seed-heads, which are very ornamental, are a magnet for goldfinches. A tough, low-maintenance perennial which will make a big clump where it’s happy, coneflower Herbstsonne holds the RHS Award of Garden Merit.
