Rudbeckia laciniata 'Herbstsonne'
Coneflower or Black eyed Susan
One of approximately 20 species of annuals, biennials and perennials from moist meadows and light woodland in North America. 'Herbstsonne' is an upright, rhizomatous, clump-forming perennial with oval, toothed or slightly lobed, prominently veined, glossy, mid-green leaves to 15cm (6in) long. From midsummer to early autumn, branching stems bear daisy-like flowerheads 10-12cm (4-5in) across, with bright yellow ray-florets and high, conical centres of green disc-florets, becoming yellowish brown with age.
Site and Care:

Slugs may damage young growth. Propagation is by seed or division in autumn or spring.
