Description
Rudbeckia subtomentosa
Also known as:sweet coneflower
,sweet black-eyed Susan
Description
Rudbeckia subtomentosa is a yellow coneflower. It grows to a height of 5 feet. The leaves are downy, green to gray-green. The yellow flowers are daisy-like, with a brown center, and exude a sweet fragrance reminiscent of anise, hence its common name.
Cultivation
Sweet coneflower is native to moist open prairies and streambanks. Moist, well-drained soils are best. This species is more shade tolerant than most of the genus, but is resentful of drought. Very easy to grow and low maintenance. Self seeds with ease without becoming aggressive. It will bloom for months, beginning in July and going until frost; October or later. Zones 5-8
Propagation
Propagate from seed, or by division in spring.
Additional Notes
Ideal for cottage gardens, where it will be a source for cut flowers until late in the season. Good for flower borders and naturalized areas.
