About

Rudbeckia Summerdaisy's Bronze Bicolor is a herbaceous perennial in the Asteraceae that forms a clump of deciduous foliage and flowers from July to October. It suits full sun to partial shade and favours moist but well-drained soils. The plant tolerates a wide range of soil types and pH levels and will stand in south-, west- or east-facing positions.

About the genus

Rudbeckia is a plant genus in the Asteraceae or composite family. Rudbeckia flowers feature a prominent, raised central disc in black, brown shades of green, and in-between tones, giving rise to their familiar common names of coneflowers and black-eyed-susans. All are native to North America, and many species are cultivated in gardens for their showy yellow or gold flower heads that bloom in mid to late summer.

In the garden

Rudbeckia Summerdaisy's Bronze Bicolor is a clump-forming herbaceous perennial in the Asteraceae grown for its summer to autumn flowering, which runs from July to October. It is deciduous and performs across a broad range of soils — chalk, clay, loam or sand — and copes with acid, neutral or alkaline pH so long as the soil remains moist but well-drained. Place it in full sun or partial shade on a south-, west- or east-facing site; it tolerates both exposed and sheltered positions. In UK terms the plant is H6, very hardy through typical winters; give established clumps room in borders or containers to avoid crowding. Its tolerance of different soils and exposures makes it suited to informal and cottage schemes, prairie or wildflower meadow mixes, wildlife gardens and mixed flower borders. It also works well in patio containers where regular watering keeps rootzone moisture steady. Use it where a reliable late-summer into autumn display is needed — it supplies stems for cutting and integrates readily with perennial borders and prairie planting schemes, extending seasonal interest into October.
