Ive had this plant for about four years. Its also sometimes called a Naked Coneflower. It is an unusual plant, but not at all showy. It has done fairly well for me, but not as well as my other Rudbeckias. I moved this plant three times before I found a place for it where it was happy; it seems to like partial sun and moist soil. It also shows up better when planted in front of a white or light colored plant.

I had two of black beauties for the past 5 years, but this year neither one made it through the winter. They always did well and required no maintance. They didn't show any signs of stress last summer so I'm not sure what happend as we had a mild winter this year.

I've sown seeds at 20C indoors...seeds germinated very slowly so I guess it's best to sow the seeds in pots and leave it on a safe place where it has enough time to germinate. Intriging flowers...
