Although I have had Brown-Eyed Susan bloom the first year Rudbeckia Triloba. Very good for low table arrangements. There are many black eyed susan varieties and cultivars of this particular species.

Rudbecika is a large perennial that requires significant root development. Increasing the cold duration from 10 to 15 weeks resulted in more flower buds on Coreopsis Gaillardia and Heuchera but had no effect on Rudbeckia. For some reason rudbeckia were not very popular by the consumer The only rudbeckia that sold ok was Indian Summer in years past I have sold a lot more. It takes a lot of energy for a bulb to flower and small bulbs often do not have the energy and resources required for the lily to grow and display flowers in the first year.
