Rudbeckia maxima is a bold clump forming perennial wildflower. A super-sized black-eyed Daisy with sturdy upright stems and a strong architectural presence. The bold attractive basal leaves grow to around 40cm long and have a lovely bluish waxy patina. Stalks rise from the foliage to around 180cm tall and are topped in early summer by bright yellow daisies. Each daisy-like head consists of a beefy elongated dark brown cone and a ring of drooping clear yellow rays. This unique species thrives in sunny sites with deep moist soils or in average garden conditions and will tolerate drought conditions once well established. Slowly spreading by rhizomes to make a good sized clump. A perfect addition to a naturalistic planting scheme.
