Description

Rudbeckia fulgida var. deamii is a naturally occurring variety of R. fulgida, with a small native range limited to IL, IN, and OH. It is similar in many ways to the straight species, and can be difficult to differentiate without a side by side comparison. At 5" long and up the 3" across, its conspicuously toothed leaves tend to be larger than those of the straight species and, along with the stems, are also hairier. It is also slightly taller and with smaller flowers (1" to 2" across). These are however borne in profusion and the overall effect of the plant is more elegant than the straight species as well as tits most common cultivar 'Goldstrum'.

Cultivation

This variety of orange coneflower is easy to grow, very adaptable, and low maintenance. Its preference is full to part-sun, but it is not particular about soil. This plant is very robust and, once established, will tolerate extended dry spells with ease. Good air circulation should be provided if grown in areas with high heat and humidity, however, it is far less susceptible to foliar disease than is the commonly sold cultivar R. fulgida 'Goldstrum'. It benefits from a long blooming period of up to 3 months, which can be extended by deadheading, from July to October. Although its native range is very limited, its performance in cultivation has been remarkable from zones 4 to 9.

Propagation

Although it does not self-seed aggressively, it is easy to propagate from seed. Clumps can be divided in spring, after new growth emerges.

Additional Notes

Rudbeckia fulgida var. deamii is very attractive to a number of pollinators, and the seeds are favored by songbirds. Deer tend to nibble on the plants early in the growing season, but generally leave them alone once they begin to set flowers.
